Module Installation

Caution—Routing Switch 9304M and 9308M

To avoid hardware damage during module installation, be careful to properly line up the edges of the module board with the guides built into the module slot on the chassis.

Getting Started

You can initially access the routing switch in either of the following ways:

■ Via Telnet or FTP through port 1 on the management module, using the factory default IP address (209 .157.22.254)

and subnet mask (255.255.255.0)

■ By connecting a terminal device to the serial port on the management module

Note: HP recommends that you use the console cable provided with the routing switch. If you need to use a different cable, please see the "Console Cable" entry under "Accessory Parts List" on the next page.

After you have accessed the routing switch, change the default IP address and subnet mask to correspond to your network’s addressing scheme. For more on assigning an IP address and other topics, see the following:

Operating Notes, Troubleshooting, and Errata

Redundant Management Module Operation

When two redundant management modules are installed in an HP 9304M or 9308M Routing Switch, the two modules work together as active and standby management modules. If the active module becomes unavailable, the standby module automatically takes over system operation. If this occurs, the routing tables, ARP tables, etc. are all updated dynamically, as if the routing switch had been rebooted. As a result of this reconvergence, a noticeable, temporary network disruption will occur. The duration of the disruption depends on the number of routes being utilized through the device, and can be significant.

Default Spanning Tree Protocol (STP) Settings

Pages 5-12 and 8-31 in Book 1: Installation and Getting Started Guide, and page 17-7 in Book 2: Advanced Configuration and Management Guide, incorrectly state that STP is enabled by default on the HP 6208M Switch. The default STP setting for the 6 208 M switch as wel l as the 93 04M, 9 308M, a nd 63 08M r outing sw itch es is "di sabled ". On all of these devices, STP must be enabled at the system level to allow assignme nt of this capability to the VLAN level. For more information on STP, see:

■ The next topic, "Configuring Single-Instance Spanning Tree Protocol (STP)" on page 4.

■ "Enabling or Disabling Spanning Tree Protocol (STP)" on page 8-31 in Book 1: Installation and Getting

Started, that was shipped with your devic e

■ Book 2: Advanced Configuration and Management (included on the Product Documentation CD-ROM

shipped with your device):

• "Spanning Tree Protocol" on page 17-7

• "Enable Spanning Tree on a VLAN" on page 17-19

• "spanning-tree" on page B-153

Configuring Single-Instance Spanning Tree Protocol (STP)

Beginning with softwa re release 05.2.14, you can configure either single-instan ce or m ultiple-instance spanning t re e on the HP 9304M, 9308M, and 6308M- SX routing swit ches, and the HP 6208M-SX Switch. When single -instance STP i s enabled, all VLANS on the device belong to the same spanning tree VLAN—with a shared STP VLAN ID of 4094. When multi-instance STP is used, each VLAN has a unique spanning tree ID.

To enable single-instance STP:

1. Enable single-instance STP globally.

2. Enable STP on each interface on which you want STP to operate.

• On the 9304M, 9308M, and 6308M-SX routing switches, you can enable STP on a per port or per VLAN basis.

• On the 6208M switch, enabling single-instance STP init ially applies to all VLANs in the switch. You can use the no spanning tree command to disable STP on individual VLANs in the switch.

Example of Single-Instance STP Configuration: Beginning at the User EXEC level of the CLI, execute the following:

HP9308>enable HP9308#configure terminal HP9308(config)#spanning-tree single HP9308#wr mem

Enables single-instan ce S TP globally. Saves the configuration change to memory.

Single instance STP must be enable d f or each VLAN that participates in the spanning-tree algorithm. The configuration file will show whether STP is enabled for a specific VLAN. In the following example, VLAN 100 is configured for STP (participating in the STP algorithm), while VLAN 101 is not.

HP9308(config)#vlan 100 HP9308(config-vlan-100)#span

Continuing from above, this command enab les single-instance STP o n VLAN 100. ("100" is the <vlan ID>.)

HP9308(config)#wr mem

Saves the configuration change to memory.

After executing the above commands, the show config command will list the following VLAN/STP information:

ver 05.2.1x

Shows the software version number for t he device.

! span single ! vlan 100 by port

tagged ethe 3/1 to 3/2 span

! vlan 101 by port

Indicates single-instance STP is enabled on the device. "span" indicates single-instance STP is configured on VLAN 100.

(Note: on the 6208M-XS switch, the word "span" does not appear , even though the device has been enabled for that VLAN.)

"no span" indicates that STP is not configured on VLAN 101.

tagged ethe 3/1 to 3/2 no span

When multiple-instan ce STP is enabled, if VLAN 100 uses STP a nd VLAN 101 does n ot, the configurat ion file generated by show config shows the following:

ver 05.2.1x

Shows the software version for the device.

! global-stp

Indicats that m u lt iple-instance STP is enabled on the device.

! vlan 100 by port

tagged ethe 3/1 to 3/2

In the case of multiple-instance STP, the VLAN(s) on which STP is running are indicated by the presence of span.

span ! vlan 101 by port

tagged ethe 3/1 to 3/2

For more information on STP, see "Default Spanning Tree Protocol (STP) Settings" on page 3.

Implementing Spanning Tree Protocol (STP) in a Tagged VLAN Environment

Condition. The HP ProCurve 9304M, 9308M, and 6308M-SX routing switches and the 6208M-SX switch offer both multiple-instance and single-instance spanning tree. The HP ProCurve 1600M, 2400M, 2424M, 4000M, and 8000M switches use sing le-instan ce spanni ng tree o nly. In a ne twork whe re multi ple-inst ance ST P is confi gured o n a 9304M , 9308M, 6308M-SX, or 6208M-SX, STP will fail on a connection between any of these devices and a single-instance STP device if the ST P Priority parameter settings are left at their defaults. (In most cases, the 6308M-SX and 6208M-SX would be used in the core network, and would not be configured for multiple-instance STP.) That is, if one or more of the single-instance STP-enabled switches in the network uses the default STP Priority parameter setting (32768), then one of these switches will become the root bridge (due the MAC addresses in these switches being lower than the MAC addresse s in the multiple -instan ce STP de vices). When thi s occurs , STP fail s on any links b etween t he (root bridge) switch and any multiple-instance STP device (9304M, 9308M, 6308M-SX, or 6208M-SX) to which the switch is connected.

9308M Routing Switch

STP enabled (multiple instance)

Switch 8000M

STP enabled (single instance)

Switch 8000M

STP enabled (single instance)

For STP to operate properly in this example, the 9308M STP Priority parameter must be lower than the Priority parameter setting in the Switch 8000Ms. (See "Solution", bel ow.)

Solution. Interoperability testing indica t es that the STP configuration allows for prop er interoperation between a 9304M, 9308M, 6308M-SX, or 6208M-SX (configured for multiple-instance STP) and a 1600M, 2400M, 2424M, 4000M, or 8000M switch in a tagged V L AN environment.

1. On the 9304M, 9308M, 6308M-SX, or 6208M-SX, ensure that software release 05.2.14 or later is installed.(This release is included with devices shi pped after 10/01/99, and is also availabl e in the Support area of HP’s ProCurve website at http://www.hp.com/go/procurve).

2. Disconnect the 9304M, 9308M, 6308M-SX, or 6208M-SX from all 1600M, 2400M, 2424M, 4000M, and 8000M switches.

3. Configure the 9304M, 9308M, 63 08M-SX, or 6208 M-SX to be the root bridge. Do this by changing the STP Priority parameter to a value that is lower than the default setting of 32768. (This assumes that the STP Priority parameter in the 1600M, 2400M, 2424M, 4000M, and 8000M switch(es) is either set at the default or is set to a higher value than the Priority setting you are using in the 9304M, 9308M, 6308M-SX, or 6208M-SX.)

4. Connect the 9304M, 9308M , 6308M-SX, or 6208M-S X to the switch(es) that were disconnected in step 2 and bri ng up the network.

Operating Notes for Using the 9304M, 9308M, 6308M-SX, or 6208M-SX in a Tagged VLAN Environment.

If there is more than one of these devices in the network, the root (primary) device must have an STP Priority setting that is lower than the other such devices in the network. This ensures that the device will become the root if the primary device fails.

Caution

If there is more than one such device in a tagged VLAN environment with STP enabled, STP will fail if the link between the primary and secondary device fails while both devices continue to route packets. An STP failure will cause broadcast storms and will result in a catastrophic failure of the network. For this reason, using STP in a tagged VLAN environment with multiple device s is not recommended.

The following scenarios will cause STP to fail:

■ The 9304M, 9308M, 6308M-SX, or 6208M-SX is not configured to be the root bridge, as described above. In

this case, STP fails between any of t hese devices and an HP ProCurve switch.

■ If there is more than on e such device in the network and th ey are not directly connect ed, STP will fail between

these devices. Multiples of these devices must be directly connected to each other in order to correctly interpret each other’s BPDU (bridge protocol data unit) packets.

Auto-Negotiation Between the HP 9300M Routing Switches and Extreme Summit™ Switches

Condition. Auto-N egotiation between the HP 9300M routing switches and Extreme Su mmit switches may sometimes fail.

Solution. Disable auto-gig on the routing switch port(s) attached to the Extreme Summit switch. For example, use the following CLI commands to disable auto-gig on port 2 in slot 1 of the HP J9304M Routing Switch:

HP 9304M (config)# int e 1/2 HP 9304M (config-if-1/2)# no auto-gig

Web Management Interface Running Slow or Failing To Respond

Condition. The Web management interface on the routing switch times out or does not respond. This can occur when the routing switch CPU is processing an excessive amount of broadcast traffic.

Solution. The Web management interface recovers automatically when the CPU is sufficiently free of broadcast traffic. Because the Web management interface is a low priority for the CPU, you may want to take steps to reduce the broadcast traffic on your network. One method for doing this is to use TopTools for Hubs & Switches (version N.01.03 or later) to determine the "top talkers" on your network, then create VLANs to segment the network for optimum traffic control.

Web Management Interface "Not Available" or "In Use"

Condition. You are unable to access the Web managment interface.

Solution. A routing switch allows only one session of the Web management interface at any given time. Thus, if one user is accessing the r outin g switch via the Web, the not available or in use messages will appear to another user who is trying to access that routing swi tch through the W e b managem ent interfac e. You can, howeve r , li mit access vi a the Web management interface by assigning a password to the rout ing switch. With a password set, access via the Web management interface will be available only to users who can enter the password. For more on passwords, refer to the Installation and Configuration Guide you received with the routing switch.

Device Will Not Boot Up Due to Corrupt Operating System

Condition. The operating system (OS) is corrupt on both the primary and secondary flash memory, and the routing switch will not boot up.

Solution. The routing switch will first try to boot up using the primary OS written to flash memory. If this fails, the device automatically tr ies to bo ot from the seco ndary f lash memo ry. If this also fails, the routing switch then tries to connect to a TFTP server and boot from there. Th is will fai l if a TFTP server is not con figur ed to supp ort the rout ing switch, or is not found. You can perform this solution only if you have access to a TFTP server. Otherwise, there are TFTP applications (available on the World Wide W eb) that you can use to enable your PC to appear as a TFTP server to the routing switch. One website where such software can be found is http://www.walusoft.co.uk.

1. Using a straight-through cable, directly connect a PC or terminal to the serial port on the routing switch. (For more information on attaching a PC or terminal , refer to chapter 2, "Installation", in the Installation and Configuration Guide.)

2. Reboot the routing switch.

3. While the system is booting up, enter b at the CLI to go into the boot monitor mode.

4. Enter the following commands:

a. boot> ip address <ip address> <subnet mask> b. boot> ip default_gateway <ip address of tftp server --or-- default gateway to get to tftp server> c. boot> boot system tftp <ip address of tftp server> <configuration file name>

The routing switch will now be able to boot up over the network. a new copy of the operating system can now be downloaded to the primary and secondary flash memories via the TFTP server.
