Operating instructions

136 Cisco Systems Intelligent Gigabit Ethernet Switch Module
At this time, you should be able to ping as just described. If you cannot ping to these
addresses, and your above configuration checks were okay, proceed to the next section and
inspect the other components in this configuration.
Verifying correct operation on the Cisco Systems IGESM
Confirm your Cisco Systems IGESM configuration using the following commands.
򐂰 To confirm that you are on the correct switch, use the show platform summary command
(shows what slot you are currently on, for example, Slot 1 = CIGESM1, Slot 2 =
CIGESM2).
򐂰 Run the show run command and confirm that it matches the desired configuration as
entered in the previous steps.
򐂰 Run the show logging command and look for any unexpected errors.
򐂰 On CIGESM1 and CIGESM2, run a show int g0/1 status command. Be sure it shows:
status - connected and vlan - trunk
򐂰 On CIGESM1, run the show int g0/2 status command and make sure that it shows:
status - connected and vlan - 10
򐂰 On CIGESM2, run the show int g0/2 status command and make sure that it shows:
status - connected and vlan - 20
򐂰 Run the show interface trunk module 0 command and check for the desired output (it
should be
similar for both Cisco Systems IGESMs):
Port Mode Encapsulation Status Native vlan
Gi0/1 on 802.1q trunking 2
Gi0/2 off 802.1q not-trunking 2
.
.
.
Gi0/17 on 802.1q trunk-inbndl 2 (Po1)
Gi0/18 on 802.1q trunk-inbndl 2 (Po1)
Gi0/19 on 802.1q trunk-inbndl 2 (Po1)
Gi0/20 on 802.1q trunk-inbndl 2 (Po1)
򐂰 Run the command show etherchannel summary and check for the desired output (it should
be
similar on both Cisco Systems IGESMs):
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
u - unsuitable for bundling
U - in use f - failed to allocate aggregator
d - default port
Number of channel-groups in use: 1
Number of aggregators: 1

Note: With this configuration (per this example), you will not be able to directly ping the
management VLAN on the Cisco Systems IGESMs. This is because it is on a different
VLAN than the blade servers. Also note that, for several reasons, we highly recommend
that you do not put any blade servers on the same VLAN as the management VLAN in use
by the Cisco Systems IGESMs.
