A network engineer is configuring a routed (Layer 3) EtherChannel bundle between two Cisco switches using Link Aggregation Control Protocol (LACP). Which TWO configuration steps must be performed on the physical member interfaces to correctly establish the channel?
- Execute the `no switchport` command on each physical member interface.Answer
- Apply the `channel-group 1 mode active` command to the physical member interfaces.Answer
- CAssign the primary IPv4 address directly to each individual physical member interface.
- DConfigure matching native VLAN IDs across all interconnecting physical member interfaces.
Answer
The correct steps are executing the `no switchport` command on physical member interfaces and placing them into an active LACP mode using `channel-group 1 mode active`.
To construct a Layer 3 EtherChannel, physical member interfaces must first be converted from switchports to routed interfaces using the `no switchport` command. Next, an LACP negotiation mode (active or passive) must be configured using the `channel-group` command on those physical interfaces.
