Zorluk: OrtaLayer 2 and Layer 3 EtherChannel (LACP)

A network engineer is configuring a routed (Layer 3) EtherChannel bundle on a Cisco switch using LACP active mode across physical interfaces GigabitEthernet 0/1 and 0/2. Place the CLI configuration commands in the correct sequential order from initial interface selection to final Layer 3 IP address assignment.

  1. 1interface range GigabitEthernet 0/1 - 2
  2. 2no switchport
  3. 3channel-group 1 mode active
  4. 4interface Port-channel 1
  5. 5ip address 10.1.1.1 255.255.255.252

Cevap

The correct configuration sequence is: enter physical interface range mode ('interface range GigabitEthernet 0/1 - 2'), convert physical member links to Layer 3 ('no switchport'), configure LACP mode ('channel-group 1 mode active'), enter port-channel interface mode ('interface Port-channel 1'), and assign the IP address ('ip address 10.1.1.1 255.255.255.252').
To deploy a routed (Layer 3) EtherChannel using LACP, the physical interfaces must first be selected ('interface range GigabitEthernet 0/1 - 2') and explicitly converted to routed ports ('no switchport'). Next, the LACP active negotiation mode is configured ('channel-group 1 mode active'), creating the logical bundle. Finally, the administrator navigates into the port-channel interface ('interface Port-channel 1') and assigns the IP address ('ip address 10.1.1.1 255.255.255.252').

Adım Adım Çözüm

1
Select physical member interfaces
Enters interface range configuration mode for GigabitEthernet 0/1 and 0/2.
Configuration changes must be applied across both physical candidate interfaces simultaneously.
2
Disable Layer 2 functionality on member interfaces
Executes 'no switchport' on member interfaces.
Member interfaces must match the Layer 3 operation requirement before joining a routed EtherChannel.
3
Configure channel-group and LACP mode
Executes 'channel-group 1 mode active'.
Binds physical interfaces to channel-group 1 and actively initiates LACP negotiation.
4
Navigate to the logical port-channel interface
Enters 'interface Port-channel 1'.
Enables logical interface parameter configuration.
5
Assign Layer 3 IPv4 address
Executes 'ip address 10.1.1.1 255.255.255.252'.
Layer 3 IP addresses are configured directly on the port-channel interface, not on the individual physical member interfaces.
