Hello,
we have an S4820T and a FX2 with 2 FN410T as IO-Modules. The 2 FN410T are running in default-mode wich means that each one of them has an own Port-Channel defined on the external ports.
I try now to connect the S4820T to the IOMs and therefore defined also 2 Port-Channels connected to the external ports of the IOMs. Sounds easy, isn't it.
My config for the 8 interfaces:
--------------------------------------------
interface TenGigabitEthernet 0/0
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 45 mode active
no shutdown
!
interface TenGigabitEthernet 0/1
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 44 mode active
no shutdown
!
interface TenGigabitEthernet 0/2
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 45 mode active
no shutdown
!
interface TenGigabitEthernet 0/3
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 44 mode active
no shutdown
!
interface TenGigabitEthernet 0/4
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 45 mode active
no shutdown
!
interface TenGigabitEthernet 0/5
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 44 mode active
no shutdown
!
interface TenGigabitEthernet 0/6
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 45 mode active
no shutdown
!
interface TenGigabitEthernet 0/7
no ip address
mtu 12000
!
port-channel-protocol LACP
port-channel 44 mode active
no shutdown
!
--------------------------------------------
and for the Portchannels:
--------------------------------------------
interface Port-channel 44
description "Port-Channel zu oberen FN410T"
no ip address
mtu 12000
portmode hybrid
switchport
no shutdown
link-bundle-monitor enable
!
interface Port-channel 45
description "Port-Channel zu unteren FN410T"
no ip address
mtu 12000
portmode hybrid
switchport
no shutdown
link-bundle-monitor enable
!
--------------------------------------------
The IOMs have an IP-address and when I try to ping it I get more "not reachable" then answers. So I think there is something wrong with the config. I guess you need more info? Feel free to ask.
Best regards
