ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 119

Which two actions must you take to configure a PAgP EthernetChannel between two switches, S1 and S2? (Choose two.)

Answer options

• A. Configure the channel-group 1 mode auto command on S1.
• B. Configure the channel-group 1 mode desirable command on S2.
• C. Configure the channel-group 1 mode active command on S2.
• D. Configure the channel-group 1 mode on command on S2.
• E. Configure the channel-group 1 mode active command on S1.

Correct answer: A, B

Explanation

The correct actions are configuring the channel-group 1 mode auto command on S1 and the channel-group 1 mode desirable command on S2, as these settings allow the switches to negotiate the channel. The other options either use an incorrect mode or are applied to the wrong switch, which will not facilitate the PAgP negotiation process.
