Hello,
I am "playing" with IOS XE in a ESXi enviroment where I use two CSR1000v 3.10.5S. I'd like to do a LACP link but interfaces are always
in a suspended state. I think that this issue is not associated to vmware networking because I can see CDP BPDU's but there are no LACP
packets transmited o received by both CSR1000v. I mean that if you do "debug lacp all" you can not see any BPDU (neither tx or rx) . I can do a non-LACP link using "on" mode and everything is fine. Both routers are in "active" mode. My configuration is:
interface Port-channel1
ip address 1.1.1.1 255.255.255.0
no negotiation auto
!
interface GigabitEthernet1
no ip address
negotiation auto
cdp enable
channel-group 1 mode active
!
interface GigabitEthernet2
no ip address
negotiation auto
cdp enable
channel-group 1 mode active
!
I do not use EFP's because I think that CSR1000v does not support l2protocol tunnel:
Router-001-CR1000v(config)#interface port-channel 1
Router-001-CR1000v(config-if)# service instance 1 ethernet
Router-001-CR1000v(config-if-srv)# encapsulation untagged
Router-001-CR1000v(config-if-srv)# bridge-domain 1
Router-001-CR1000v(config-if-srv)# l2protocol peer lacp
l2protocol action not supported
Any idea why ports are in suspended state and no BPDU's are transmited?.
Regards

Hello,
I can see a BPDU transmited only when I delete the giga port from the Port-Channel:
Router-002-CR1000v(config)#interface GigabitEthernet3
Router-002-CR1000v(config-if)#no channel-group 64 mode passive
Router-002-CR1000v(config-if)#

I do not know if the LACP link is available.
