Configuring the SP Switch Router Adapter Installing an SP Switch Router Adapter card Installing an SP Switch Router Adapter card This section contains the procedure for physical installation and minimal configuration of the SP Switch Router Adapter card for use as an SP dependent node. This includes cabling the card to the SP control workstation and the appropriate SP switch port.
Configuring the SP Switch Router Adapter Installing the PCMCIA spinning disk Installing the PCMCIA spinning disk Your system is shipped with a PCMCIA disk device that is required to collect the system log files. This disk can hold up to 520MB of data. You can install the disk any time after the SP Switch Router is powered on and is running. Logging is not enabled until you install the disk and complete this configuration procedure. Logged messages can be helpful while you are configuring media cards.
Configuring the SP Switch Router Adapter Installing the PCMCIA spinning disk Panic dumps sent to external flash device The mountf and grdump commands enable the grdump program to work with an external flash device to capture media card dumps. When a media card panics and there is a formatted external flash device plugged into a PCMCIA slot, a copy of the dump is automatically saved to the external flash in a directory called /var/portcards.

Configuring the SP Switch Router Adapter Configuration required on the SP system Configuration required on the SP system This section describes the SP Switch Router-related configuration information that should be defined by the SP administrator and then entered from the SP control workstation before configuring the SP Switch Router Adapter card.
Configuring the SP Switch Router Adapter Configuration required on the SP system Procedure 1 From the SP control workstation, determine the switch_node_number by entering: SDRGetObjects DependentNode node_number==n where n is the node_number of the dependent node. This command produces output that looks like: node_number switch_node_number ... 47 2 31 ...
Configuring the SP Switch Router Adapter Configuration required on the SP system Sources of configuration information Here are several ways to determine the node number and other configuration data for a particular card. • Check the SP Switch out.top file: – The value of the switch_node_number follows the "tb3" field in file output.
Configuring the SP Switch Router Adapter Configuration required on the SP system Multiple frames for multiple system connections SP Switch Router Adapter cards in an SP Switch Router can connect to different switch boards in the same SP system. A configuration problem could arise in which the SP Switch Router Adapter cards would be assigned the same node number if each card plugged into the same port position on each switch board. The construct of a frame removes the configuration problem.
Configuring the SP Switch Router Adapter Step-by-step media card configuration Step-by-step media card configuration This section provides a configuration overview and the steps required to configure an SP Switch Router Adapter media card. Configuration files and their uses These are the /etc configuration files discussed in this chapter: grifconfig.conf - identifies each logical interface on a media card snmpd.conf - enables SNMP capabilities grdev1.
Configuring the SP Switch Router Adapter Step-by-step media card configuration 4 Run dev1config to create /etc/grdev1.conf. The SP Switch Router requires a specific configuration file, /etc/grdev1.conf, for the SP Switch Router Adapter card to operate. The dev1config command creates this skeleton file using configuration information passed to the router in either of two ways: a. We recommend using the procedures documented in the “Managing Extension Nodes” chapter of the PSSP Administration Guide.
Configuring the SP Switch Router Adapter Step 1. Check SNMP in the SP Switch Router system Step 1. Check SNMP in the SP Switch Router system Check the /etc/snmpd.conf file to see if a management station and community are defined, and if traps are enabled. Network monitoring devices (management stations) can request or access the SP Switch Router’s SNMP information. Follow the procedure described in Chapter 2 of the GRF Configuration and Management manual, “Configure SNMP.

Configuring the SP Switch Router Adapter Step 2. Assign IP addresses Step 2. Assign IP addresses You need to assign an IP address and related parameters to the SP Switch Router Adapter interface. You assign a primary IP address and, if needed, an alias address to support multiple subnets on the same physical interface. Netmasks for each address can differ in length. Refer to Appendix C, “Network Configuration Examples,” for ways to use IP addressing and subnet masks.
Configuring the SP Switch Router Adapter Step 2. Assign IP addresses Type sh at the super> prompt for the UNIX shell prompt to appear: super> sh # Interface name The SP Switch Router interface name has five components that describe an individual interface in terms of its physical slot location in the chassis, and its specific and virtual locations on a media card.
Configuring the SP Switch Router Adapter Step 2. Assign IP addresses Argument field This field is optional for SP Switch Router Adapter cards. The arguments field usually specifies an MTU value different from the coded default value of 65520.
Configuring the SP Switch Router Adapter Step 3. Change profile settings Step 3. Change profile settings Specify card-level parameters – Card profile Set specific dev1 card configuration parameters at the Card profile. The fields to set are: – OPTIONAL: specify ICMP throttling settings – OPTIONAL: change run-time binaries – OPTIONAL: change dump variables This is the card profile for the SP Switch Router Adapter card residing in slot 8.
Configuring the SP Switch Router Adapter Step 3. Change profile settings Specify different executables A media card’s Card profile can be used to specify a custom binary setting that overrides the standard media binary configured in the system Load profile. Card-specific executables can be set at the Card profile in the load / hw-table field. The hw-table field is empty until you specify the path name of a new run-time binary.
Configuring the SP Switch Router Adapter Step 3. Change profile settings value and you later read the field, the setting is always displayed in decimal.
Configuring the SP Switch Router Adapter Step 3. Change profile settings Change executables for all dev1 cards - Load profile Global values for executable binaries are set at the Load profile in the hw-table field. These only change when you want to execute new run-time code in all SP Switch Router Adapter cards. Here is the path, default settings are shown: super> read load LOAD read super> list hippi = {"" N/A on 0 1 <{1 /usr/libexec/portcards/xlxload.run N/A}+ rmb = { /usr/libexec/portcards/rm.
Configuring the SP Switch Router Adapter Step 3. Change profile settings Change dump defaults for all dev1 cards - Dump profile Global values for dump settings are at the Dump profile. These settings are usually changed only for debug purposes. Default settings are shown in this example. The keep-count field specifies how many dumps are compressed and stored at one time for each media card.
Configuring the SP Switch Router Adapter Step 3. Change profile settings To specify dump on panic and dump when card hangs, you OR together 0x0004 (dump on card panic) and 0x0010 (dump whenever card is hung). The result in hex is 0x0014, or 20 in decimal.

Monitoring and Management Tools 3 This chapter describes tools used to monitor day-to-day operations of the SP Switch Router Adapter card or to indicate the causes of problems which may develop. These tools operate from the SP Switch Router, and apply to the SP Switch Router and the SP Switch Router Adapter card. The “Management Commands and Tools” and “Management Tasks” chapters in the GRF Configuration and Management manual provide more information related to monitoring and managing the router.
Monitoring and Management Tools SP Switch Router command overview SP Switch Router command overview This section provides a brief overview of frequently-used management commands. These are administrative and configuration commands, most are prefixed with gr and most operate on the router’s internal flash. These commands manage memory and support multiple configuration versions. These include: flashcmd, getver, grfins, grsite, grsnapshot, grwrite, mountf, setver, umountf, and vpurge.
Monitoring and Management Tools SP Switch Router command overview getver This command tells you the version of the operating system that is currently running. It can also report which release version will be run the next time the system is booted. In this case, getver is used in conjunction with setver. The setver command specifies which release will be run at the next system boot. grarp The grarp command displays the ARP table for a given IP address.
Monitoring and Management Tools SP Switch Router command overview grms This command enables non-privileged users to reboot, halt, or shutdown the SP Switch Router in an orderly manner that precludes damage to the system. grreset This command resets one or more specified media cards. Options can direct that memory be dumped when the media card comes back up (grreset -D) or that the media card be held in reset (grreset -h).

Monitoring and Management Tools Checking for hardware problems - grdiag Checking for hardware problems - grdiag This section describes the diagnostic capability provided by the grdiag command. Users can run a set of internal BIST-level diagnostics to verify media card (including SP Switch Router Adapter card) hardware. A card that fails this set of diagnostics must be replaced. HIPPI media cards do not support the grdiag command.
Monitoring and Management Tools Checking for hardware problems - grdiag When a media card does not boot after grdiag For grdiag to run, a card must be able to boot. If the grcard display does not include the slot in which the problem card resides, grdiag cannot operate on that card.
Monitoring and Management Tools SP Switch Router dumps SP Switch Router dumps The SP Switch Router can be configured to send dumps to an external PCMCIA 520MB disk rather than to its own system memory. On the SP Switch Router, output from dumps, logs, and other system reporting functions refer to the SP Switch Router Adapter card as DEV1_v1 or dev1. Dumps are maintained in the directories /var/portcards and /var/crash. Dumps are compressed to save space, and the compressed files are appended with .gz.

Network Configuration Examples C The SP Switch Router provides LAN and WAN access for SP processor nodes. The SP Switch Router Adapter card and SP processor nodes are IP-addressed nodes on the SP Switch network. Three basic configurations are building blocks for more complex networking topologies that include the SP Switch Router: 1. single SP Switch Router Adapter card and single SP partition 2. multiple SP Switch Router Adapter cards and single SP partition 3.
Network Configuration Examples Example 1: Single SP Switch Router Adapter card, single SP partition In this configuration, a single SP Switch Router Adapter card is connected to a single SP partition. The IP address of the SP Switch network is 198.174.11. The partition of SP nodes is shown in the shaded area of Figure C-1. net 198.174.11.0 SP Switch Router SP processor node net 198.174.11.0 SP Switch Router Adapter card Partition SP processor node SP Switch mask 255.255.255.
Network Configuration Examples Example 2: Multiple cards, single partition This network configuration divides the traffic for an SP processor node partition between two or more SP Switch Router Adapter cards and achieves some load leveling among the SP processor nodes. It provides dual, not truly redundant, connections to the router in case of SP Switch Router Adapter card failure.
Network Configuration Examples Configuration tasks Given: – the IP network is 198.174.11.0 – the netmask is 255.255.255.0 – there can be up to 254 nodes on the network (including the two SP Switch Router Adapter cards) 1 Configure the SP processor nodes with 198.174.11.0 as the network and 255.255.255.0 as the netmask. The address of individual nodes must be between 198.174.11.1 and 198.174.11.254. 2 Configure the two SP Switch Router Adapter cards as follows: - divide the 198.174.11.
Network Configuration Examples Recovery procedure if an SP Switch Router Adapter card fails The configuration in Figure C-2 is not redundant because two active SP Switch Router Adapter cards cannot carry the same IP address. Alias addresses cannot be used if more than one of the cards sharing the address are active. An alias address can be shared between two cards if only one card is active. This is shown in Figure C-3.
Network Configuration Examples Example 3: Multiple cards, multiple SP partitions: In this configuration, subnetting is required on both the SP Switch Router and the SP system. Each subnet contains a different SP Switch Router Adapter card and a different SP processor node partition. Note that the partitions logically “cross” the SP Switch. This configuration is created by multiples of the configuration discussed in example 1. SP Switch net 198.174.11.00, SP processor node net 198.174.11.
Upgrading Router Software D This Appendix provides general information about obtaining and installing new operating software (hereafter referred to as machine code) for the SP Switch Router. The SP Switch Router as an IBM product As is noted in this manual, the SP Switch Router is based on a product from Lucent Technologies, Inc. IBM customers order and receive the SP Switch Router from IBM. IBM provides all support for this product for IBM customers.
