IEEE 802.3ad (LACP) is a technology that provides a method of aggregating multiple Ethernet links into a single logical channel.<\/span><\/p>\n

Configuration<\/span><\/strong><\/h2>\n

To configure LACP the following commands are used. This example aggregates the interfaces fe-0\/0\/3 and fe-0\/0\/4 into a logical interface named ‘ae1’. This logical interface is then configured as an access port and assigned to vlan ‘vlan-trust’.<\/span><\/p>\n

set chassis aggregated-devices ethernet device-count 2
set interfaces fe-0\/0\/3 fastether-options 802.3ad ae1
set interfaces fe-0\/0\/4 fastether-options 802.3ad ae1
set interfaces ae1 unit 0 family ethernet-switching port-mode access
set interfaces ae1 unit 0 family ethernet-switching vlan members vlan-trust
set interfaces ae1 aggregated-ether-options lacp active<\/span><\/pre>\n
Once configured and commited the running configuration (for your new aggregated interfaces) will look like this,<\/span><\/p>\n
chassis {
    aggregated-devices {
        ethernet {
            device-count 2;
        }
    }

 interfaces {
!
    fe-0\/0\/3 {
        fastether-options {
            802.3ad ae1;
        }
    }
    fe-0\/0\/4 {
        fastether-options {
            802.3ad ae1;
        }
    }
    ae1 {
         aggregated-ether-options {
            lacp {
                active;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode access;
                vlan {
                    members vlan-trust;
                }
            }
        }
    }<\/pre>\n
Testing<\/strong><\/h2>\n
To confirm that the interface is up run the following command,<\/p>\n
root@srx# run show interfaces terse | match ae1
fe-0\/0\/3.0              up    up   aenet    --> ae1.0
fe-0\/0\/4.0              up    up   aenet    --> ae1.0
ae1                     up    up
ae1.0                   up    up   eth-switch<\/pre>\n
If you then need to show further information on your aggregated interface you can run the command,
<\/span><\/p>\n
