What mode is PAgP?

Port Aggregation Protocol (PAgP) has two Channel modes and they are “Desirable” and “Auto”.

Which mode are in PAgP choose two?

There are three modes available when configuring an interface for PAgP: on, desirable, and auto.

Which PAgP mode combination will establish an EtherChannel?

Explanation: Switch 1 and switch 2 will establish an EtherChannel if both sides are set to desirable as both sides will negotiate the link.

What are Lacpdu packets?

LACP allows a network device to negotiate an automatic bundling of links by sending LACP packets to their peer, a directly connected device that also implements LACP. Maximum number of bundled ports allowed in the port channel: Valid values are usually from 1 to 8.

Which two channel group modes would place an interface in a negotiating state using PAgP?

Answers Explanation & Hints: There are three modes available when configuring an interface for PAgP: on, desirable, and auto. Only desirable and auto place the interface in a negotiating state. The active and passive states are used to configure LACP and not PAgP.

What is desirable mode in PAgP?

Desirable mode: Desirable mode in Port Aggregation Protocol (PAgP) initiates the negotiation and tries to form EtherChannel with other end. If you are using Port Aggregation Protocol (PAgP) for EtherChannel negotiation, EtherChannel will be formed only if two ends are configured under folowing modes.

What is PAgP (PAgP)?

PAgP is Cisco proprietary Etherchannel technology. It uses the multicast address of 01-00-0C-CC-CC-CC for communication. Switch/Router Ports can form an EtherChannel when they are in different PAgP modes as per below criteria –. A port in the desirable mode can form an EtherChannel with another port that is in the desirable or auto mode.

What is auto mode in PAgP?

Auto Mode: Auto mode in Port Aggregation Protocol (PAgP)) does not initiate the negotiation, but responds to Port Aggregation Protocol (PAgP) packets initiated by other end. Auto mode in Port Aggregation Protocol (PAgP) does not start Port Aggregation Protocol (PAgP) packet negotiation

What are the different modes of EtherChannel negotiation in PAgP?

Desirable mode: Desirable mode in Port Aggregation Protocol (PAgP) initiates the negotiation and tries to form EtherChannel with other end. If you are using Port Aggregation Protocol (PAgP) for EtherChannel negotiation, EtherChannel will be formed only if two ends are configured under folowing modes.
