Zorluk: KolayLayer 2 and Layer 3 EtherChannel (LACP)

A network administrator needs to configure a routed (Layer 3) EtherChannel using LACP dynamic negotiation across physical interfaces GigabitEthernet0/1 and GigabitEthernet0/2 on a Cisco switch. Place the configuration steps in the correct sequential order from first to last.

  1. 1Enter interface range configuration mode for physical member interfaces GigabitEthernet0/1 and GigabitEthernet0/2.
  2. 2Execute the 'no switchport' command on the physical member interfaces to disable Layer 2 switching functionality.
  3. 3Execute the 'channel-group 1 mode active' command on the physical member interfaces to initiate LACP negotiation.
  4. 4Enter logical interface Port-channel 1 configuration mode and assign the IPv4 address and subnet mask.

Cevap

The correct sequence of steps to configure a Layer 3 EtherChannel using LACP is: 1) Enter interface range configuration mode for the physical member interfaces; 2) Execute the 'no switchport' command on the physical member interfaces; 3) Execute the 'channel-group 1 mode active' command on the physical member interfaces; 4) Enter logical interface Port-channel 1 configuration mode and assign the IPv4 address and subnet mask.
The proper administrative workflow begins by selecting physical member links GigabitEthernet0/1 and GigabitEthernet0/2. Disabling Layer 2 switching on these interfaces via 'no switchport' establishes them as routed interfaces. Binding them to channel-group 1 using LACP active mode creates the logical port-channel and begins dynamic trunk negotiation. Finally, navigating into interface Port-channel 1 mode permits configuration of the routed IP address.

Adım Adım Çözüm

1
Select physical member links
Switch prompt changes to (config-if-range).
Allows configuration changes to be applied simultaneously across both physical interfaces.
2
Disable Layer 2 switchport mode on physical interfaces
'no switchport' command converts physical member links into routed ports.
Layer 3 EtherChannels require member interfaces to operate as routed ports rather than Layer 2 switchports.
3
Enable LACP active mode on physical interfaces
'channel-group 1 mode active' dynamically creates logical interface Port-channel 1.
Active mode ensures the switch actively initiates LACP negotiation across the member links.
4
Assign IP address to the logical port-channel
IPv4 address and subnet mask are configured on interface Port-channel 1.
For Layer 3 EtherChannels, IP routing occurs on the aggregate logical interface.
