What is the EtherChannel protocol being used with the command "channel-group 10 mode" configured?

The command "channel-group 10 mode" is a partial command used in the configuration of EtherChannel on networking devices, but without specifying a particular mode or protocol, it does not clearly indicate which EtherChannel protocol is being used. In the context of EtherChannel, there are typically three protocols: LACP (Link Aggregation Control Protocol), PAgP (Port Aggregation Protocol), and static EtherChannel.

If the command was followed by a specific mode, such as "active" for LACP or "desirable" for PAgP, that would clarify which protocol is in use. However, if the command does not indicate a specific protocol or mode, then it is interpreted that none of the specified protocols are actively in use at that point in the command structure. Therefore, simply using "channel-group 10 mode" without further context or specification leads to the conclusion that it defaults to none of the Ethernet aggregation protocols being explicitly defined.

This highlights the importance of being specific in configuration commands and how their interpretation can depend on the context in which they are used. In instances where an EtherChannel configuration is incomplete, it’s essential to verify subsequent commands to determine the protocol in use.
