Hi all,
There are two CE8860s that are configured M-LAG and connected to the access switch.
If the access switch is connected to only one CE, the STA can obtain the IP address. However, if the access switch is connected to the two CEs, the STA cannot obtain the IP address. Only DHCP request packets are sent out, but no response packet is returned.
m-lag configuration:
interface Eth-Trunk100
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 5
mode lacp-static
dfs-group 1 m-lag 100
dhcp snooping trusted
Topology
Any solutions will be appreciated!
