Hi,
i have tried to configure the Ethernet OAM between Cisco switch and Huawei Switch, Pls find the below topology
Topology:
Problem Observed
- When we tried to remove the single core from the Huawei switch then both the switch interface down
- We have enabled the error recovery on both the switches
- After the recovery interval cisco switch connected interface is came up(Te1/16) due to this we are facing the unidirectional issue
Configurations:-
Cisco 4500:-
interface TenGigabitEthernet1/16
