Switching

You are asked to verify the CLI output for the link-aggregation configuration for one mobility gateway cluster member below.

Which configuration is valid?

Explanation

An Aruba Mobility Gateway LACP port-channel applies its port-channel trunk properties to the member links. A compatible aggregate for this VSX multi-chassis LAG must use trunking with native VLAN 100, permit/trust VLANs 1–4094, and place both physical interfaces in LACP group 0 in active mode with the short timeout. This preserves the upstream LAG’s native-VLAN and all-VLAN trunk requirements.
