Page 17: Chapter 1 Overview Of The Ethernet Switch Blade
Chapter 1 Overview of the Ethernet Switch Blade The Ethernet Switch Blade is a 72-port AdvancedTCA® Hub and providing Gigabit Ethernet. Up to 14 ATCA node boards may be addressed via the PICMG 3.0 Base Interface and via the ATCA PICMG 3.1 fabric . The Base and Fabric switching domains are kept totally separate, both on the physical layer and the software layer.
Page 18: Openarchitect Switch Management
OpenArchitect Switch Management The OpenArchitect software component – open source Linux, IP protocol stack, control applications and the OA Engine – runs on two embedded PowerPC microprocessors.

Page 21 network-enabled Linux implementation. The purpose of the routing table is to tell the packet forwarding software where to forward the data packets. In Linux, the packet-forwarding algorithm is operated in software. Normally, the routing tables are maintained by operator configuration and the various routing protocols that run in the application environment of Linux.

The RS-232 configured RJ-45 connector console port on the front panel can be used to recover from a system failure. It is used for maintenance only, and is generally not connected. Use a HP console cable (P/N A6900-63006) provided with the HP bh5700 ATCA 14-Slot Blade Server, in combination with a Modem Eliminator cable, to access the switch software through the console port.

Page 27: Chapter 3 High Availability Networking
Chapter 3 High Availability Networking High availability networking is achieved by eliminating any single point of failure through redundant connectivity: Redundant cables, switches and network interfaces for hardware, combined with HA software solutions on both the hosts and switches to control the HA hardware and maintain connectivity.
Page 28: Vrrp
VRRP Since most end nodes use default router addresses, the change of the default router address during a switch failover would require the end nodes to reconfigure. Layer 3 switches that failover must maintain the default router address to maintain the end node's IP transparent failover. The Virtual Router Redundancy Protocol (VRRP, RFC 2338) running in the Surviving Partner switches provides transparent movement of the default router address.
Page 29: Switch Replacement And Reconfiguration
Switch Replacement and Reconfiguration When a switch fails, it must be replaced. The replacement switch will likely require proper configuration. For transparent switch replacement, the newly replaced switch must learn its configuration from its Surviving Partner. In a simple failover scenario, Host A and Host B are configured with failover between two host ports, one port connected to Switch A and the other connected to Switch B.
Page 30: Example Ha Switch Configuration
The configuration and runtime scripts created are as follows: S70Surviving_partner Switch initialization script that is run at boot time. This • script will restart the switch with the original configuration given to zspconfig. Optionally, zspconfig will run this script from the initial invocation. zsp.conf.<n>...
Page 31: Modifying Zsp.conf On The Base Switch
When using a Linux Bonding driver on the node card, the bonding driver should be configured for Mode 1 (active/standby). See the Linux Bonding documentation at http://sourceforge.net/projects/bonding/ for complete information. The two Base switches will be configured as Surviving Partners, using VRRP to form a single virtual interface to the hosts, as will the two Fabric switches.

Page 33 #vrrp_mode: block_crossconnect; The next sections determines the failover mode between the Surviving Partner switches. There are three modes: switch - Failover by switch. Failover from Master switch to Backup on any port • failure. The switch with the most links becomes the new Master. One port failure will cause the switch to failover.

Finally, it lets the currently saved S70Surviving_Partner script execute. This case would be the case of a power up of an already configured backup switch when the other HA switch is unavailable. This case could occur after losing power to the entire chassis. Central Authority Modifications can be made to the S60SP_startup script to use a third machine running DHCP that is not part of the Surviving Partner pair.

For example, the S60SP_startup script line that reads: echo y n | zspconfig -t 10 -su zhp0 >...
Page 46: Chapter 4 Fabric Switch Configuration
Chapter 4 Fabric Switch Configuration Two switches, two consoles There are two separate switch portions in the Ethernet Switch Blade units, the base switch and the fabric switch. The fabric switch handles the data traffic for the ATCA rack over ports 0-47. It runs the Ethernet Switch Blade software.
Page 47: Changing The Shell Prompt
Changing the Shell Prompt You may use standard bash shell procedures to change the prompts on your base switches. Many sites choose a system that distinguishes among the individual switches at their location. The same rules apply for saving your choice (zsync) as for all other configuration changes. Default Configuration Scripts As shipped the following scripts are run from as the switch boots up:...
Page 48: Overview Of Openarchitect Vlan Interfaces
Overview of OpenArchitect VLAN Interfaces A zhp device is associated with one VLAN. zhp may have one or more physical ports and their associated zre devices. A VLAN from the viewpoint of the switch is a logical mapping of ports based on intended use.
Page 49: Switch Port Interfaces
Switch Port Interfaces For each switch port, OpenArchitect creates a separate interface with its own MAC address called a ZNYX raw Ethernet (zre). After the initial power up, 48 zre interfaces are created, one for each in band port. You cannot directly access or modify the zre interfaces. During the initial power up of the switch, the default configuration creates a Layer 2 switch.
Page 50: Using The S50Layer2 Script
ifconfig zhp1 0.0.0.0 # At this point the system will act as a Layer 2 switch # across all ports. Also, the system will accept telnet() # connections on 10.0.0.43 on any port. Script(s) may then # be run to reinitialize the system and modify its # configuration.
Page 51: To Enable Rapid Spanning Tree
To Enable Rapid Spanning Tree: Create a VLAN containing the ports that will be a part of the Linux bridge running Rapid Spanning Tree. This example will use ports 0-3 (untagged): zconfig zhp0: vlan1=zre0..3 zconfig zre0..3=untag1 Create a bridge device from the zhp device, zl2d start zhp0 A Bridge device named bzhp0 should now exist consisting of ports zre0 through zre3 with Spanning Tree enabled.
Page 52: Layer 3 Switch Configuration
Layer 3 Switch Configuration The previous section outlines the Layer 2 switch configuration that is automatically configured when you initially bring up the OpenArchitect switch. In order to communicate between Layer2 interfaces, you must properly setup routing. The steps to build a Layer 2 switch involve creating a group of switch ports in a VLAN (or Layer 2 switching domain) and bringing that interface up.
Page 53 In the S50layer3 script separate VLANs are set up for each port. The VLANs, are labeled as zhp0..zhpn. Each VLAN is associated with an individual zre interface. There is always a one to one connection between VLANs and zhp interfaces. Remember, zre and zhp interfaces can begin with a zero value but a VLAN cannot (that is, zhp0 has zre0 on vlan1, zhp1 has zre1 on vlan2).

Page 58: Marking And Re-Marking
Marking and Re-marking The OpenArchitect switch can mark or remark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utility. Scheduling The servicing of configured queues by the switching fabric is referred to as scheduling. The OpenArchitect switch has three built-in scheduling algorithms.
Page 59: Restrictions On Implementation
you may want to move your set of iptables commands to a start up script to run upon initialization. This could be accomplished by creating a standalone "S" script and placing that script into / etc/rcZ.d. Restrictions on Implementation Several restrictions exist on the rules that can be implemented on the FFP hardware. These include: Actions DROP the packet.
Page 60: Iptables And Filtering
On the other hand, in the following sequence of rules, the position of the rule that drops SYN packets is important. Since the set of fields it examines is not a subset of the fields examined by the ACCEPT rules, and visa versa, the ordering rule given above does not apply. In this case, the order it is applied will be the same as its position in the FORWARD chain, and all packets which are TCP SYN packets from zhp5 for zhp3 will be DROPPED, even if they also match one of the ACCEPT rules.
Page 61: Packet Walk
By default, INPUT, FORWARD and OUTPUT chains are installed on boot up. Additional rules can be installed for the other chains. Additionally, one can write software extensions to add more chains. Figure 4.2 provides an illustration of the Firewall Flow. R o u t i n g P o s t F o r w a r d...
Page 62: Filter Rules Specifications
send to CPU action is specified, it is sent to the INPUT chain for further processing. If there is no valid way to forward the packet, it is dropped. If the switch is configured to forward the packet, it is sent to the FORWARD chain. Next the hardware FORWARD chain is walked.
Page 63: Specifying Tcp Or Udp Ports
The type can be preceded by ! to match any message except the type listed, for example, -- icmp-type ! 1 Specifying TCP or UDP ports If the protocol is TCP or UDP, the -s ( or --sport) and -d (or --dport) options specify the TCP or UDP ports to match.

This will force the full installed chains traversal in software --set-eport <val> Redirect the packet to port <val> --set-mport <val>...
Page 65: Tc And Zqosd
FORWARDING Chain supports all of them. tc and zqosd tc, which stands for Traffic Control, is a mechanism for enabling Quality of Service on Linux. tc uses three functional objects: queuing disciplines, which comprise queuing and scheduling algorithms such as FIFO queues, priority queues, RED queues, and token buckets; classes, which are leafs in queuing discipline hierarchies;...
Page 66 qdisc pfifo 100: dev zhp0 limit 32p The tc command is applied to a device, so dev zhp0 must be specified. Note that a VLAN, such as zhp0, and a port, such as zre0, are each treated as devices. Breakdown of the options: handle 100:0 Defines the handle for the queuing discipline.
Page 67: Prio And Wrr Queues
The byte-limited FIFO queue case differs only slightly from the packet-limited FIFO case. The syntax is almost identical. In hardware the limit is based on 128-byte cells. The specified byte limit is divided by 128 to determine the cell limit. Always specify a byte limit of at least 128 bytes to avoid setting the queue length to zero.
Page 68 index of the list element (numbering from 0) and q is the value specified by that element. So, this example would read: Priority 0 maps to Queue 1 Priority 1 maps to Queue 2 Priority 2 maps to Queue 2 Priority 3 maps to Queue 2 Priority 4 maps to Queue 3 Note that the tc priority map applies to a 4-bit field.
Page 69: The U32 Filter
The U32 Filter The U32 filter provides the capability to match on fields in the L2, L3 or L4 header of a packet. Each match rule gives the location of the field to be tested, which is always a 32 bit word, a mask selecting the bits to be tested, and a value which is to be matched by the packet field.
Page 70: Handle Semantics
Although the translation rules handle some inconsistency between software and hardware, a user must define a combination of rules that is reasonable in hardware, to ensure predictable results. Handle Semantics All examples have illustrated zqosd copying tc rules into hardware. In fact, the zqosd utility also enables the user to add tc rules that remain only in software.
Page 71: Protocol Architecture
The PDP sends that policy to the PEP. • The PEP installs the policy and applies it to future traffic. • As long as COPS is running, a connection between the PEP and PDP should stay open. A PEP could query a PDP at any time asking for a policy decision. Alternatively, an administrator could modify the policy on a PDP, which would then push any policy changes to its PEPs.
Page 72: Using Pepd
The pepd utility requires a PDP that has implemented the above RFCs and drafts. Until all draft standards are approved, the certain COPS-PR data types will not be assigned OIDs. pepd uses non-standard OIDs for the unassigned values. Using pepd The pepd utility works by connection to a PDP, informing the PDP of its roles, and installing any rules that the PDP has for those roles.
Page 73: Chapter 5 Fabric Switch Administration
Chapter 5 Fabric Switch Administration One of the main benefits of the OpenArchitect switch is that it runs Linux, so much of the switch administration is already familiar to most network or system administrators. It is a good idea to complement these instructions with a standard Linux reference guide, such as Linux Network Administrator’s Guide available from O’Reilly.

Marking and Re-marking The OpenArchitect switch can mark or remark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utility. Scheduling The servicing of configured queues by the switching fabric is referred to as scheduling. The OpenArchitect switch has three built-in scheduling algorithms.
Page 107: Running Zfilterd
Running zfilterd Before starting zfilterd, ztmd must be running. Your can start both from within a script, or directly from the command line. For example, ztmd zfilterd iptables rules can be entered at any time. If your iptables filtering rules set is extensive, you may want to move your set of iptables commands to a start up script to run upon initialization.

action that will take place. For example, the rules: iptables -a FORWARD -i zhp3 -j DROP iptables -a FORWARD -i zhp3 -o zhp1 -p tcp --dport smtp -j ACCEPT result in SMTP packets received on any port in zhp3 to be sent for any port in zhp1; all other packets from zhp3 would be dropped.
Page 109: Introduction
Introduction Firewall rules are stored in tables. These tables are sometimes also known as firewall chains or just chains. Tables normally store rules for what are known as hooks, which can be looked as packet-path junctions. There are five defined hooks: PRE-ROUTE, POST-ROUTE, INPUT, OUTPUT and FORWARDING.
Page 110: Packet Walk
Packet Walk When a packet comes in via one of the interface ports, the base switch makes a routing decision. If the packet was destined for the base switch itself or if the send to CPU action is specified, it is sent to the INPUT chain for further processing.
Page 111: Specifying Tcp Or Udp Ports
Supported Targets The following are the supported targets. The switch has many additional targets that are software based (example Network Address Translation or generic connection tracking). Please contact HP Technical support if you have additional questions on additional features. Classical Targets DROP This drops the packet.

handle 100:0 Defines the handle for the queuing discipline. This handle may be used to reference the pfifo queue. Note that the handle is included with the output of the qdisc ls command. (100:0 and 100: are equivalent in tc.) The choice of handle is significant for zqosd.

match ip tos 0xa0 0xe0 would match an IP precedence of 5. Specific fields can also be specified by giving their offset from the beginning of the IP header and a field name of u8, u16, or u32, depending on the width of the field. For example, to match the SYN bit in the TCP flags, the specification is: match u8 2 0x02 at 33 Several IP fields can be matched in the same filter by specifying multiple match operations.

and relaying those requests to its PDP. By contrast, the provisioning model is based on longer lasting policy. The expectation is that policy should be administratively defined at the PDP and pushed to the PEPs as needed. OpenArchitect is a COPS-PR client. The most common use of COPS-PR is for distributing Differentiated Services (Diffserv) policy.

Page 128: Chapter 8 Base Switch Administration
Chapter 8 Base Switch Administration One of the main benefits of the OpenArchitect switch is that it runs Linux, so much of the switch administration is already familiar to most network or system administrators. It is a good idea to complement these instructions with a standard Linux reference guide, such as Linux Network Administrator’s Guide available from O’Reilly.

This VLAN includes four switch ports, zre1, zre10, zre11, zre13. zhp0: vlan100 = zre1,zre10,zre11,zre13; The next statement adds two switch ports, zre1, zre2 and zre3, to an existing network interface and VLAN. zhp0: vlan100 = zre1..3; The next statement deletes two switch ports, zre1 and zre2, to an existing network interface and VLAN.
Page 204 zre1=untag1; If port 0 is also a member of VLAN 100, packets for VLAN 100 are sent from this port with a VLAN tag as part of their header. In the next example, the switch ports 10, 11, and trunk 2 are configured as untagged members of VLAN 100.
Page 205 The following statement creates 14 VLAN groups with VID numbers 1-14. Each VLAN contains the same switch port, port 1, represented as zre1. zhp0..13: vlan1..14 = zre1; The plus (+) wildcard can be used with the last port listed to auto-increment that port number before each VLAN group is created.

Page 274: Zconfig
zconfig NAME zconfig - Configures the OpenArchitect switch. SYNOPSIS zconfig [-h <host_name>] [-d <level>] [-a] [-t] [{-f <file>} | <configuration>] DESCRIPTION zconfig creates VLAN groups of switch ports or trunks. Each VLAN group forms a Layer 2 switching domain. Each VLAN group has a VLAN Identification number (VID) that can be carried in a tag field, located in the header of packets traveling on that VLAN.
Page 275 entered as parameters to zconfig. CONFIGURATION SYNTAX zconfig takes configuration data from standard input or from a file with the -f option. In either case, the configuration syntax is the same. The zconfig configuration data consists of a list of semicolon-delimited statements. Each statement specifies an action to take globally or on an interface.
Page 276 A port member is identified with the zre<X> format, where x represents a port number between 0 and 23 for the in-band ports. The Out-of-Band ports cannot be included in the List of ports. teardown Removes the trunk interface, making the ports which were part of the trunk available for configuration in other trunks or VLANs.
Page 277 Network Interface Statements The syntax for a network interface statement is the interface name followed by a colon and an action. Network interface statements are used to create or tear down a VLAN group and can consist of one or a list of network interface names; followed by a colon and then an action. For example: zhp0: <Network Interface Action>;...
Page 278 The next statement creates a VLAN group with the VID number 100 and the network interface named zhp1. This VLAN includes four switch ports, zre1, zre10, zre11, zre13. zhp0: vlan100 = zre1,zre10,zre11,zre13; The next statement adds two switch ports, zre1, zre2 and zre3, to an existing network interface and VLAN.
Page 279 tag are given the VLAN tag with the VID number 1, enter: zre1=untag1; If port 0 is also a member of VLAN 100, packets for VLAN 100 are sent from this port with a VLAN tag as part of their header. In the next example, the switch ports 10, 11, and trunk 2 are configured as untagged members of VLAN 100.
Page 280 network interface, and all ports listed after the equal sign are included in each group. The following statement creates 14 VLAN groups with VID numbers 1-14. Each VLAN contains the same switch port, port 1, represented as zre1. zhp0..13: vlan1..14 = zre1; The plus (+) wildcard can be used with the last port listed to auto-increment that port number before each VLAN group is created.
Page 281 The previous configuration can be used for creating a 14 port Layer 2 switch, all 14 ports assigned to the same VLAN. SEE ALSO zl3d Ethernet Switch Blade User's Guide release 3.2.2j page 281 Downloaded from www.Manualslib.com manuals search engine...

Page 328: Zspconfig
zspconfig NAME zspconfig - configure and start surviving partner SYNOPSIS zspconfig [-d <level>] [-p <directory_path>] [-u <dhcp_interface>] [-c <dhclient.conf>] [-t <timeout>] [-s] [-v] -f <file> DESCRIPTION zspconfig is used to configure and start the Surviving Partner software. With the -f option a configuration file is provided that completely describes the network setup and desired behavior of all of the switches participating in the Surviving Partner.
Page 329 finding a Surviving Partner to retrieve configuration information from. Only valid with the –u option. Do not ask for confirmation. Run from a script. Prints the current version of zspconfig. -f <file> The provided <file> is used as input to configure the Surviving Partner.
Page 330 A sibling_addresses statement is required for each VLAN created with the zconfig commands. The two addresses in the list indicate there are two switches in the Surviving Partner group. The first address 10.0.0.30 and 11.0.0.30 are assigned to the switch on which the configuration is being run.
Page 331 monitor_only - Ports that are monitored but do not have a virtual address managed on them. They will not have their links brought down temporarily during a failover scenario. These ports are only monitored. If a problem occurs on this type of link it will cause a failover scenario.
Page 332 interconnect, it is not a bonding driver enabled port, and therefore should be setup as an interconnect port type. To accomplish this, the zre ports are listed to avoid conflicting port types. Note that a single line cannot contain both zhp and zre definitions. Therefore RAINlink: zhp1, zre1..4 does not work and the definition zre1..8 is equivalent.
Page 333 Coordination between the data and fabric switches can be enabled by setting the board_synchronization_mode. Possible modes are “off” and “basic”. Board synchronization is off by default. When board synchronization is put into basic mode, HA events on the base switch are coordinated with the HA events on the fabric switch. The behavior of board synchronization is dependent on the failover_mode.
Page 334 files run the Surviving Partner. This is a list of all configuration and script files: /etc/rcZ.d/S70Surviving_partner The main startup script that starts the Surviving Partner by running zconfig, ifconfig, zlmd and vrrpd. zspconfig prompts the user to run this script. This file can be saved with zsync to automatically start the Surviving Partner at switch boot.

Page 336: Zstack
zstack NAME zstack - Configures the OpenArchitect switch stacking. SYNOPSIS zstack [-h <host_name>] [-d <level>] [-a] [-t] [{-f <file>} | <configuration>] DESCRIPTION zstack combines multiple switch fabric chips into a single virtual switch. zstack must be run before any other switch configuration. Specifically it must be run before zconfig. zstack is typically run from an S20stack script prior to the S50xxx scripts.
Page 337 semicolon-delimited statements. Each statement specifies an action to take on a stack. A stack is a group of ports on a single switch fabric chip. Actions include stack creation, stack port association, stack configuration and stack control. Comments, spaces and new lines are ignored. Comments begin with the # character and include characters through the next new line.
Page 338 semicolon are two zre_lists separated by an equal sign. The first is the list of virtual port names, the second is the physical port names. The assignment is done in order, and there must be an equal number of ports in each list. Wild cards may be used in the zre_lists. See below. Stack port association syntax for a base switch: stack0: zre0..11 = zre0..11;...
Page 339 Stack Control Statements Finally after creating the stack, associating the ports, and setting the stack configuration, the stack can be enabled using one of the Stack Control statements. The following stack control statements are supported. enable; The enable statement turns on stacking that has been previously configured. This statement cannot be made until configuration is complete.
Page 340: Ztats
ztats NAME ztats − Display statistics and information about switch SYNOPSIS ztats [-d <level>] [-i <unit>] | [-m <port>] | [-v <vlan id>] | [-t <tgid>] | [-v] DESCRIPTION ztats displays MIB counters for a selected physical port, trunk group or VLAN. It can also display information about the configuration of the switch and bridge to the PCI bus or the Vital Product Data memory.
Page 341: Zsync
zsync NAME zsync − Saves changes to the flash. SYNOPSIS zsync [-c][-f][<dir_or_file>] zsync [-c][-f][-t <file>] zsync [-c][-f][-z] zsync [-c][-l] DESCRIPTION zsync is used to save a snapshot of the current file system to flash ROM. By default, zsync creates a compressed tar image of the files that have changed and saves the image in the flash ROM.
Page 342 OPTIONS Save files to the custom overlay -t <file> Read files to be saved from a tar file. Zero the overlay area. Do not confirm with user and do not warn if saving failed. Exit code can be examined to determine success or failure. <dir_or_file>...
