A fire district wants to bundle two 10G uplinks toward a distribution pair and must choose how the EtherChannel negotiates. Which choice best reduces silent misconfiguration risk during onboarding?
Select an answer to reveal the explanation.
Short Explanation
LACP is the handshake before two fire hoses get Y’d together. If one side isn’t ready, negotiation fails safe instead of half-forwarding. Static ‘on’ mode skips the handshake and can leave a nasty one-sided bundle during onboarding.
Full Explanation
LACP (channel-group mode active/passive) negotiates EtherChannel membership so incompatible or miswired members are less likely to form a broken bundle. Mode on forces the channel without LACP and can create unidirectional or inconsistent forwarding if the peer is wrong. Mixing LACP on one side with static on the other does not negotiate correctly, and STP cost tweaks alone do not aggregate bandwidth. Prefer LACP for resilient, detectable bundling on distribution uplinks.
