Dear, I'm trying to create a lacp port channel between a Nexus and ASR 903
Everything work well using a " switchport mode access" while by using the portchannel as Trunk the Portchannel goes down and the interfaces related to it went to suspended state on the Nexus side.
Kindly find below configuration On the ASR router
Interface Te0/0/3
no ip address
channel-group 21 mode active
exit
Interface Te0/0/4
no ip address
channel-group 21 mode active
exit
interface Port-channel21
no ip address
load-interval 30
service instance 3500 ethernet
description test vlan 1
encapsulation dot1q 3500
rewrite ingress tag pop 1 symmetric
bridge-domain 3500
!
service instance 3600 ethernet
description test vlan 2
encapsulation dot1q 3600
rewrite ingress tag pop 1 symmetric
bridge-domain 3600
!
interface BDI3500
ip address 192.168.243.1 255.255.255.252
end
interface BDI3600
ip address 192.168.243.5 255.255.255.252
end
And that is my configuration on My Nexus Switch:
vlan 3500
exit
vlan 3600
exit
interface port-channel 21
interface Eth 1/23
channel-group 21 mode passive
exit
interface Eth 1/24
channel-group 21 mode passive
exit
interface port-channel 1
switchport mode trunk
switchport trunk allowed vlan 3500,3600
exit
the show port-channel summary on the Nexus
