Nortel Networks L2/3 Ethernet Switch Module for IBM
Eserver
BladeCenter
9.1 Basic rules and unique symptoms
Before going into detail about troubleshooting, it is important to first discuss certain common
rules and symptoms for this environment. Certain interactions within the IBM
Eserver
BladeCenter between the Nortel Networks L2/3 GbESM and the Management Module require
that certain important rules are followed. Failure to follow these rules can produce
unexpected results when deploying the IBM
Eserver
BladeCenter containing an Nortel
Networks L2/3 GbESM. In this section, we summarize some of these rules and the
consequences of not adhering to them. We also discuss some symptoms that you might see
and possible solutions for these.
9.1.1 Basic rules
Review the following rules:
1. Do
not
attach cables to the Nortel Networks L2/3 GbESM until
both
sides of the
connection are configured.
– Symptoms: No upstream connectivity, upstream network failure from spanning tree
loop.
– Solution: Keep cables disconnected or ports shut down until properly configured on
both
sides of the connection. This is an important best practice for
any
switch-to-switch
connections in a production network, not just between the Nortel Networks L2/3
GbESM and its upstream connections.
2. Do
not
put Blade servers on the subnet that the Nortel Networks L2/3 GbESM uses for its
management VLAN interface.
– Symptoms: Unable to reach the switch from server blades or from external devices
attached to the Management Module port.
– Solution: Use a separate subnets for the management module.
3. Make sure the Nortel Networks L2/3 GbESM firmware code is upgraded to the most
current version of the Alteon OS. You can find the latest code for the Nortel Networks L2/3
GbESM at:
http://www.ibm.com/support
When you go to this Web site, do the following:
a. Under Support topics, click Downloads and drivers.
b. Under Category, select BladeCenter (Blades).
c. Click BladeCenter chassis Hardware only.
d. Click Firmware.
e. Scroll to find the desired Nortel Networks L2/3 GbESM Firmware - IBM
Eserver
BladeCenter.
Note: It is not possible to put external ports on VLAN 4095, which is dedicated to the
Management Module. It is essential that the PVID of ports INT1-14 be a VLAN other
than 4095 and that ports INT1-14 are each members of at least one such
data-bearing VLAN
