To configure LACP:

1. Configure the interfaces for ae0.
2. Configure ae0 interface for vlan tagging.
3. Configure LACP for ae0 and configure periodic transmission of LACP packets.
4. Configure ae0 as a trunk port.
5. Configure the VLAN.
6. Add the ae0 interface to the VLAN.

show lacp interfaces

1. Syntax. content_copy zoom_out_map. show lacp interfaces < interface-name > extensive.
2. Description. Display Link Aggregation Control Protocol (LACP) information about the specified aggregated Ethernet, Fast Ethernet, or Gigabit Ethernet interface.
3. Options. none. Display LACP information for all interfaces.

Enable/Disable Interface in Juniper

1. [email protected]# set interfaces ge-0/0/1.0 disable << This is cisco equivalent of “shutdown” – To Juniper enable interface:
2. [email protected]# delete interfaces ge-0/0/1.0 disable << This is cisco equivalent of “no shutdown” Verification:
3. [email protected]#show ge-0/0/1.0.

LACP is one method of bundling several physical interfaces to form one logical interface. You can configure both VLAN-tagged and untagged aggregated Ethernet with or without LACP enabled. For Multichassis Link Aggregation (MC-LAG), you must specify the system-id and admin key .

Link Aggregation Control Protocol (LACP) has two Channel modes and they are “Active” and “Passive”.

You can display a detailed report or a summary of the LACP status by using the show command. You can view specific information about the load-balancing and frame-distribution schemes, specific information about the individual ports in the port channel, and general information about the port channel settings.

Accessing a Juniper Networks Device the First Time

1. Connect a terminal or laptop computer to the device through the console port.
2. Power on the device and wait for it to boot. The software boots automatically.
3. Log in as the user root .
4. Start the command-line interface (CLI).
5. Enter configuration mode.

Knowledge Base

1. From configuration mode, create the VLAN and add access vlan members to it:
2. Verify the VLAN and interface: root# run show vlans.
3. Configure the trunk and add VLAN that was created in previous steps:
4. Verify the trunk and the VLAN members for this trunk: root# run show interfaces ge-0/0/.0.

Creating a Channel Group The port channel is configured in port-channel configuration mode. Configuration changes to a port channel interface propagate to all Ethernet interfaces in the corresponding channel group. LACP is enabled on the member interfaces by setting the channel-group mode to active or passive.

Core isolation state down (CDN)— LACP interface state. Down indicates the LACP interface is down because all the eBGP sessions for Ethernet VPN (EVPN) are down. Link state (active or standby) indicated in parentheses next to the interface when link protection is configured.

The Junos OS implementation of LACP provides link monitoring but not automatic addition and deletion of links. The LACP mode can be active or passive. If the actor and partner are both in passive mode, they do not exchange LACP packets, which results in the aggregated Ethernet links not coming up.

The LACP mode can be active or passive. If the actor and partner are both in passive mode, they do not exchange LACP packets, which results in the aggregated Ethernet links not coming up. If either the actor or partner is active, they do exchange LACP packets. By default, LACP is turned off on aggregated Ethernet interfaces.

The LACP port ID consists of the port priority as the two most-significant octets and the port number as the two least-significant octets. The system with the numerically lower value for port priority has the higher priority. By default, port priority is 127, with a range of 0 to 65,535.
