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

Switch-A(config-if-range)#channel-protocol lacp Switch-A(config-if-range)#channel-group 1 mode active Switch-A(config)#interface range fastEthernet 0/1 - 2 It is better to start the configuration after shutting down the switch ports to avoid any negotiation issues while configuring LACP. Let’s start configuring LACP in Switch-A. The links between the switches are TRUNKS so we have to configure TRUNK in the LACP bundled port as well. We can bundle these two switch ports into one logical EtherChannel using Link Aggregation Control Protocol (LACP) protocol. The switches are connected with two switch ports Fa0/1 and Fa0/2. The diagram below shows a simple scenario with two Cisco switches, Switch-A and Switch-B. Whereas, in passive mode, the port just waits for remote switch port to initiate LACP negotiation. In active mode, the port actively tries to form LACP EtherChannel with remote switch port. The physical switch ports running LACP protocol can be either in active or passive mode. Configure LACP EtherChannel in Cisco IOS Switch In this post, I will show steps to Configure LACP EtherChannel in Cisco IOS Switch.

Link Aggregation Control Protocol (LACP) is a industry standard (IEEE 802.3ad) protocol that is used to bundle two or more links and can work with devices from different vendors. If you are using PAgP protocol then you must use Cisco switches because PAgP is Cisco proprietary protocol. Link Aggregation or Ether Channel is a technology which allows for two or more physical ports to combine into one logical port providing high availability and increased bandwidth.
