A network administrator is connecting two Cisco Catalyst switches via a multi-link bundle using Link Aggregation Control Protocol (LACP). Which two conditions or configuration settings are required for the EtherChannel bundle to form and operate correctly? (Select two.)
- At least one of the switches must have its physical member interfaces configured in LACP active mode.Cevap
- All physical member interfaces in the bundle must be configured with identical speed, duplex, and VLAN settings.Cevap
- CConfiguring both switches in LACP passive mode allows the bundle to negotiate successfully once initial data frames are sent.
- DIf member physical trunk ports have mismatched native VLANs, LACP automatically harmonizes the VLAN configuration across the bundle.
Cevap
The EtherChannel bundle successfully forms when at least one side is configured in LACP active mode and all member interfaces share matching operational parameters such as speed, duplex, and VLAN configurations.
For an LACP EtherChannel to form, at least one endpoint must actively send LACP packets (active mode), allowing negotiation when paired with an active or passive remote interface. Additionally, all bundled physical interfaces must have identical speed, duplex, switchport mode, native VLAN, and allowed VLAN attributes.
