which cisco ios switch command is used to configure the use of lacp on an interface?

LACP is part of an IEEE specification (802.3ad) that allows several physical ports to be bundled together to form a single logical channel.

With the on mode, a usable EtherChannel exists only when an interface group in the on mode is connected to another interface group in the on mode. Places an interface into an active negotiating state, in which the interface starts negotiations with other interfaces by sending PAgP packets.įorces the interface to channel without PAgP. This setting minimizes the transmission of PAgP packets and is the default. Places an interface into a passive negotiating state, in which the interface responds to PAgP packets it receives but does not start PAgP packet negotiation. The EtherChannel is then added to the spanning tree as a single bridge port. When PAgP identifies matched Ethernet links, it groups the links into an EtherChannel. PAgP packets are sent between Fast EtherChannel-capable ports to negotiate the forming of a channel. IEEE standard Link Aggregation Protocol ( LACP).Cisco’s proprietary Port Aggregation Protocol ( PAgP).There are two protocols used for the link aggregation: If a link within the EtherChannel bundle fails, traffic previously carried over the failed link is carried over the remaining links within the EtherChannel. All interfaces in each EtherChannel must be the same speed and duplex, and both ends of the channel must be configured as either a Layer 2 or Layer 3 interface. EtherChannel bundles individual Ethernet links into a single logical link that provides bandwidth up to 1600 Mbps (Fast EtherChannel, full duplex) or 16 Gbps (Gigabit EtherChannel) between two Cisco Catalyst switches.
