we have a 7210 controller where currently 1 port channel is configured with 2 x 10 Gbit fibre interfaces. We want to change that into 2 x 1 GBit utp interfaces.
Mixing interfaces of different speed is not supported. So i thought of retrieving the config, modify, return the new config, and boot from it...
Unfortunately, after booting from the new config, the network is no longer working. And i do not see any error. When executing 'show running' the command seems to hang...
We just moved the lines :
lacp timeout shortlacp group 1 mode active
from interfaces 2 and 3 to interfaces 0 and 1, which should be sufficiant.
interface gigabitethernet 0/0/0description "GE0/0/0"trustedtrusted vlan 1-4094!
interface gigabitethernet 0/0/1description "GE0/0/1"trustedtrusted vlan 1-4094!
interface gigabitethernet 0/0/2description "GE0/0/2"trustedtrusted vlan 1-4094lacp timeout shortlacp group 1 mode active!
interface gigabitethernet 0/0/3description "GE0/0/3"trustedtrusted vlan 1-4094lacp timeout shortlacp group 1 mode active
Anyone having an idea?
Make sure that new port channel is trusted on the Aruba Controller.
Actually, i did not change the port channel config :
interface port-channel 1trustedtrusted vlan 1-4094switchport mode trunkswitchport trunk native vlan 101switchport trunk allowed vlan 101-102,208
I just changed the interfaces which were in the port-channel.
If that is an up to date version of the config, it would say what physical interfaces are added under the port channel. Those interfaces are not in your config.
It would say :
interface port channel 0
add interface gigabitethernet 0/0
add interface gigabitethernet 0/1
Those last two lines are crucial and are missing..
Okay, turned out the Aruba config was correct. And i had to add vlan 1 to the trunk on the HP switches before the aggregate came online.
