Zorluk: OrtaLayer 2 and Layer 3 EtherChannel (LACP)

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?

  1. Execute the `no switchport` command on each physical member interface.Cevap
  2. Apply the `channel-group 1 mode active` command to the physical member interfaces.Cevap
  3. C
    Assign the primary IPv4 address directly to each individual physical member interface.
  4. D
    Configure matching native VLAN IDs across all interconnecting physical member interfaces.

Cevap

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.

Adım Adım Çözüm

1
Convert physical member interfaces to Layer 3 mode
The physical interfaces cease operating as Layer 2 switchports.
Layer 3 EtherChannels require member links to operate as routed ports.
2
Enable LACP negotiation on physical member interfaces
Physical interfaces send LACP packets to initiate bundle negotiation.
Setting the channel-group mode to active enables LACP dynamic negotiation.
