I'm having an issue very similar to this issue listed here
I have a dozen working port channels with the exact same configuration as the one I've recreated, but my new LACP / port-channels do not see one another on their partner switches via VLT. Both switches are configured identically, I can send full configs if it would be helpful, but I'm really struggling to see why this happens when we are recreating the LACP after replacing/upgrading/rebuilding hosts.
WORKING port channel:
MXL-B1(conf-if-te-0/8)#show config
!
interface TenGigabitEthernet 0/8
description To Slot 8
no ip address
!
port-channel-protocol LACP
port-channel 8 mode active
no shutdown
!
interface Port-channel 8
description Slot 8 LACP
no ip address
portmode hybrid
switchport
vlt-peer-lag port-channel 8
no shutdown
BROKEN port channel:
!
interface TenGigabitEthernet 0/9
description To Slot 9
no ip address
!
port-channel-protocol LACP
port-channel 9 mode active
no shutdown
!
interface Port-channel 9
description Slot 9 LACP
no ip address
portmode hybrid
switchport
vlt-peer-lag port-channel 9
no shutdown
Am I missing something for the vlt config? how do I get these two switches to see their partner?
Here's the LACP status for the port channel that I've recreated.
Port-channel 9 admin up, oper down, mode lacp
Actor System ID: Priority 32768, Address f8b1.5606.4388
Partner System ID: Priority 0, Address 0000.0000.0000
Actor Admin Key 9, Oper Key 9, Partner Oper Key 0, VLT Peer Oper Key 9
LACP LAG 9 is an individual link
LACP LAG 9 is a VLT LAG
A - Active LACP, B - Passive LACP, C - Short Timeout, D - Long Timeout
E - Aggregatable Link, F - Individual Link, G - IN_SYNC, H - OUT_OF_SYNC
I - Collection enabled, J - Collection disabled, K - Distribution enabled
L - Distribution disabled, M - Partner Defaulted, N - Partner Non-defaulted,
O - Receiver is in expired state, P - Receiver is not in expired state
Port Te 0/9 is enabled, LACP is enabled and mode is lacp
Port State: Not in Bundle
Actor Admin: State ADEHJLMP Key 9 Priority 32768
Oper: State ADEHJLMP Key 9 Priority 32768
Partner is not present
LLDP NEIGHBOR
The results of show lldp neighbor for these specific ports is odd vm8 is correct below:
