To display LACP information for a port-channel, use the show lacp port-channel Privileged EXEC mode command.

In this example, we will be looking at GE1/0/1 statistics for LACP. To display LACP information for all Ethernet ports or for a specific Ethernet port, use the show lacp Privileged EXEC mode command. Use the command below: SG550X#show interfaces port-channel To verify that your port-channel has been created. You should now have configured LAG on your interfaces through the CLI. If you want to save your running configuration to the startup configuration, please follow steps 11-13 in the previous section: LAG Configuration Procedure. SG550X(config-if-range)#lacp system-priority value In this example, we will be using the default value of 1.

LACP uses the system priority with the switch MAC address to form the system ID and also during negotiation with other systems. They can be configured automatically or through the CLI). LACP system priority must be configured on each switch running LACP. To restore the default configuration, use the no form of this command. To set the system priority, use the lacp system-priority Global Configuration mode command. To exit any mode and bring the user to the next higher mode in the CLI mode hierarchy, use the exit command. SG550X(config-if-range)#lacp timeout long SG550X(config)#port-channel load-balance ДЇor this example, we will be using the default value of long for our LACP timeout. In this example, we leave the load balacing as the default option.

src-dest-mac-ip - Port channel load balancing is based on the source and destination of MAC and IP addresses.

src-dst-mac - Port channel load balancing is based on the source and destination MAC addresses.

To configure the load balancing policy of the port channeling, use the port-channel load-balance Global Configuration mode command. From the Privileged EXEC mode of the switch, enter the Global Configuration mode by entering the following: SG550X#configure If you are unfamiliar with terms in this document, check out Cisco Business: Glossary of New Terms.

#Lag switch program how to#

This document explains how to configure LAG on a switch through the Command Line Interface (CLI). Additionally this helps in changing the LAG speed, advertisement, flow control, and also protection which can be easily identified in LAG settings table.

It is also responsible for bandwidth multiplication, increase in port flexibility, and in providing redundancy on links between any 2 devices. LACP helps to form one single LAG by bundling many physical ports. Traffic load balancing over the active member ports of a LAG is managed by a hash-based distribution function that distributes unicast and multicast traffic based on Layer 2 or Layer 3 packet header information. Link Aggregation Control Protocol (LACP) is a part of IEEE specification (802.3az) that can control the bundling of several physical ports together to form a single logical channel. Link Aggregation Group (LAG) multiply the bandwidth, increase port flexibility, and provide link redundancy between two devices.
