A network engineer is configuring a routed (Layer 3) EtherChannel between two Cisco Catalyst switches, Switch-1 and Switch-2, across physical interfaces GigabitEthernet 0/1 and GigabitEthernet 0/2. Switch-1 is configured with LACP in active mode (`channel-group 10 mode active`). Which TWO requirements must be met to correctly establish and operate this Layer 3 LACP EtherChannel bundle? (Select two choices.)
- The `no switchport` command must be applied to both the logical interface Port-channel 10 and the physical member interfaces prior to configuring the IP address.Cevap
- Switch-2 physical member interfaces can be configured with `channel-group 10 mode passive` to negotiate the LACP bundle successfully.Cevap
- CSwitch-2 physical member interfaces must be configured with `channel-group 10 mode auto` to dynamically form the link bundle with Switch-1.
- DIndividual IP addresses must be assigned directly to physical member interfaces GigabitEthernet 0/1 and GigabitEthernet 0/2 to enable routing across both bundle members.
Cevap
The correct requirements are converting both the physical member interfaces and the logical port-channel interface to Layer 3 using the 'no switchport' command before assigning the IP address, and configuring Switch-2 in LACP passive mode (or active mode) to pair with Switch-1 active mode.
For Layer 3 EtherChannels, physical member ports and the port-channel interface must be configured as routed interfaces via `no switchport`, and the IP address is assigned to the logical port-channel interface. Furthermore, LACP allows dynamic bundle establishment when one side is in active mode and the peer side is in passive mode.
