350-401 Practice Question: The maximum number of active member links…

What is the maximum number of active member links supported in a single EtherChannel on Cisco Catalyst switches?

⚠ Common exam trap

Cisco often tests the distinction between the maximum number of configured ports (16 with LACP) versus the maximum number of active ports (8), leading candidates to mistakenly choose 16.

Correct answer & explanation

8

Cisco Catalyst switches support a maximum of 8 active member links in a single EtherChannel. This limit is defined by the IEEE 802.3ad standard and Cisco's implementation, ensuring that the load-balancing algorithm distributes traffic effectively across all links. The 8-link limit applies to both PAgP and LACP modes.
