Example: Configuring Aggregated Ethernet Device with LAG and LACP (CLI)
Requirements
No special configuration beyond device initialization is required before configuring this feature.
Overview
This example shows the configuration of aggregated Ethernet (ae) devices with LAG and LACP.
Configuration
Step-by-Step Procedure
To configure LAG:
- Configure the number of ae devices with LAG interface
that you need to create.[edit]user@host# set chassis aggregated-devices ethernet device-count 5
- Add a port to the ae device with LAG.[edit]user@host# set interfaces ge-2/0/1 gigether-options 802.3ad ae0user@host# set interfaces ge-2/0/2 gigether-options 802.3ad ae0
- Configure LACP for the ae device with LAG.[edit]user@host# set interfaces ae0 aggregated-ether-options lacp active
- Configure family Ethernet switching for the ae device
with LAG.[edit]user@host# set interfaces ae0 unit 0 family ethernet-switching
- Configure VLAN.[edit]user@host# set vlans vlan20 vlan-id 20
- Add the ae interface to the VLAN.[edit]user@host# set vlans vlan20 interface ae0
- Check the configuration by entering the show vlans and show interfaces commands
user@host# show vlans vlan20 { vlan-id 20; interface { ae0.0; } }user@host# show interfaces ge-2/0/1 { gigether-options { 802.3ad ae0; } } ge-2/0/2 { gigether-options { 802.3ad ae0; } } ae0 { aggregated-ether-options { lacp { active; } } unit 0 { family ethernet-switching; } } - If you are done configuring the device, commit the configuration.[edit]user@host# commit
Note: Likewise, you can configure other devices with LAG and LACP.
Verification
Verifying Aggregated Ethernet Device with LAG and LACP
Purpose
Verify that you can configure ae devices with LAG and LACP.
Action
From configuration mode, enter the show lacp interfaces to view the LACP interfaces.
user@host# run show lacp interfaces
Aggregated interface: ae0
LACP state: Role Exp Def Dist Col Syn Aggr Timeout Activity
ge-2/0/1 Actor No No Yes Yes Yes Yes Fast Active
ge-2/0/1 Partner No No Yes Yes Yes Yes Fast Active
ge-2/0/2 Actor No No Yes Yes Yes Yes Fast Active
ge-2/0/2 Partner No No Yes Yes Yes Yes Fast Active
LACP protocol: Receive State Transmit State Mux State
ge-2/0/1 Current Fast periodic Collecting distributing
ge-2/0/2 Current Fast periodic Collecting distributing
From configuration mode, enter the show vlans command to view the VLAN interfaces.
user@host# run show vlans Name Tag Interfaces default 1 None vlan20 20 ae0.0
From configuration mode, enter the show interfaces (interface name) command to view the status of the ge-2/0/1 and ge-2/0/2 interfaces.
user@host# run show interfaces ge-2/0/1 terse Interface Admin Link Proto Local Remote ge-2/0/1 up up ge-2/0/1.0 up up aenet --> ae0.0
user@host# run show interfaces ge-2/0/2 terse Interface Admin Link Proto Local Remote ge-2/0/2 up up ge-2/0/2.0 up up aenet --> ae0.0
