A network administrator needs to establish a routed (Layer 3) EtherChannel between two Cisco switches using LACP active mode across physical interfaces GigabitEthernet0/1 and GigabitEthernet0/2. In what correct chronological order should the administrator execute the Cisco IOS CLI commands to configure this Layer 3 EtherChannel from global configuration mode?
- 1Enter interface range configuration mode for physical member interfaces: interface range GigabitEthernet0/1 - 2
- 2Convert physical interfaces to Layer 3 routed interfaces: no switchport
- 3Bind the physical member interfaces to EtherChannel group 10 using LACP active mode: channel-group 10 mode active
- 4Enter logical port-channel interface configuration mode: interface Port-channel 10
- 5Assign the IP address directly to the logical port-channel interface: ip address 10.10.10.1 255.255.255.252
Answer
The correct configuration order requires selecting physical member interfaces first, converting them to Layer 3 routed ports using 'no switchport', assigning them to EtherChannel group 10 with LACP active mode, entering Port-channel 10 configuration mode, and finally configuring the IPv4 address on the logical Port-channel interface.
The correct order follows Cisco standard CLI logic for Layer 3 EtherChannel configuration: select physical member interfaces ('interface range GigabitEthernet0/1 - 2'), convert them to routed ports ('no switchport'), form the LACP EtherChannel bundle ('channel-group 10 mode active'), navigate into the logical interface ('interface Port-channel 10'), and assign the IP address ('ip address 10.10.10.1 255.255.255.252').

Key Concept
Layer 3 EtherChannel CLI configuration workflow requires setting 'no switchport' on physical member interfaces prior to creating the channel-group and applying IP addressing on the logical Port-channel interface.
