A network administrator is provisioning a routed Layer 3 EtherChannel bundle between a core switch and a distribution switch using the Link Aggregation Control Protocol (LACP). Which two configuration requirements or operational conditions must be met for the Layer 3 EtherChannel bundle to successfully form and forward traffic? (Select two.)
- The 'no switchport' command must be executed on both the logical port-channel interface and all physical member interfaces before configuring an IP address on the port-channel.Cevap
- BBoth switches must have their physical member interfaces configured in LACP 'passive' mode to allow silent negotiation without generating excess control frames.
- At least one side of the connection must have its member interfaces configured in LACP 'active' mode to actively send LACP control packets.Cevap
- DEach physical member interface must be assigned a unique native VLAN ID prior to converting the bundle to Layer 3.
Cevap
The two correct requirements are: executing the 'no switchport' command on both the logical port-channel and physical member interfaces before assigning an IP address to the port-channel, and ensuring that at least one switch is set to LACP 'active' mode to initiate LACP negotiations.
To operationalize a Layer 3 EtherChannel, all member interfaces and the logical port-channel interface must be configured with 'no switchport' to disable Layer 2 switching before assigning an IP address to the port-channel. Additionally, LACP negotiation requires at least one end to actively transmit LACP frames by using 'active' mode.
