Quick question, and I can't seem to find the answer. Any * represents "priviledged" info. I don't want to break any rules.
On our 6509E, we have an EtherChannel programmed as follows:
interface Port-channel45
description PortChannel to **********
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan ***,****
switchport mode trunk
switchport nonegotiate
no ip address
shutdown
spanning-tree portfast trunk
spanning-tree bpduguard enable
end
And the interfaces associated with the etherchannel are as follows:
interface GigabitEthernet3/15
description **********
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan ***,***
switchport mode trunk
switchport nonegotiate
no ip address
shutdown
speed 1000
duplex full
no mdix auto
flowcontrol send off
no cdp enable
spanning-tree portfast
spanning-tree bpduguard enable
channel-group 45 mode on
end
!
interface GigabitEthernet4/15
description **********
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan ***,***
switchport mode trunk
switchport nonegotiate
no ip addresse
shutdown
speed 1000
duplex full
no mdix auto
flowcontrol send off
no cdp enable
spanning-tree portfast
spanning-tree bpduguard enable
channel-group 45 mode on
end
When I issue the "show port-channel summary" and "sho run int po45" commands, the port-channel shows up as follows:
#sho etherchannel sum
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
Number of channel-groups in use: 33
Number of aggregators: 33

However, when the "sho ip int brief" and the "sho interfaces description" commands are executed, the newly created port-channel does not show up.
#sho ip int bri

We have several port-channels (32 total) that are identically configured (for the most part - allowed vlans and associated interfaces are different). Do you have any insight as to why the device would omit Port-Channel 45 from the interface brief and interface description show commands while displaying the others? And will it have an adverse effects on the network?
Thank you!
