Which protocol allows you to create EtherChannels in a propriety environment? Question 11Select one:PortFastMSTPLACPPAgP

Breakdown the Problem

We need to identify the protocol that facilitates the creation of EtherChannels in a proprietary networking environment. The options are:

1. PortFast
2. MST (Multiple Spanning Tree)
3. LACP (Link Aggregation Control Protocol)
4. PAgP (Port Aggregation Protocol)

Relevant Concepts

1. PortFast: A feature that allows a switch port to immediately transition to the forwarding state, but it is not related to EtherChannel creation.
2. MST: Facilitates spanning tree protocol configurations but does not deal with EtherChannel creation.
3. LACP: A standard protocol for collecting multiple links into a single logical link, but it is not proprietary.
4. PAgP: A Cisco proprietary protocol that automates the creation of EtherChannels.

Analysis and Detail

• PortFast is valuable for reducing the time a port takes to become active but does not create EtherChannels.
• MST manages VLANs and port states regarding the spanning tree but does not deal with EtherChannel aggregation.
• LACP, while widely used, is based on an industry standard rather than a proprietary approach.
• PAgP, on the other hand, is specific to Cisco devices and allows automatic aggregation of links into an EtherChannel.

Verify and Summarize

Given the context of a proprietary environment, the most suitable option for creating EtherChannels is PAgP, as it is specifically designed for use in Cisco environments.

Final Answer

The protocol that allows you to create EtherChannels in a proprietary environment is PAgP (Port Aggregation Protocol).
