Configuring Port-Channel and VLAN in Juniper

Objective: To configure port-channel and associate it to vlan.

Servers will use Juniper-Router as their gateway and uplink to Internet. Server-switch have Layer 2 (access mode) connectivity to Juniper-Router. (see Fig.1)

 Fig.1

1. Configure the Vlan (interface vlan will be the server's gateway)

Juniper-Router#

configure

set vlans VLAN-8 description Server-Farm

set vlans VLAN-8 vlan-id 8

set vlans VLAN-8 l3-interface irb.8

set interfaces irb unit 8 description "Server Farm Vlan"

set interfaces irb unit 8 family inet address 192.168.8.1/24

2. Configure port-channel

set interfaces ae10 description "Port-channel to Server-Switch"

set interfaces ae10 aggregated-ether-options link-speed 1g

set interfaces ae10 aggregated-ether-options lacp active

set interfaces ae10 unit 0 family ethernet-switching interface-mode access

set interfaces ae10 unit 0 family ethernet-switching vlan members VLAN-8

3. Configure physical members

set interfaces ge-0/0/0 description "Connection to Server-Switch fa1/0"

set interfaces ge-0/0/0 gigether-options 802.3ad ae10

set interfaces ge-0/0/1 description "Connection to Server-Switch fa2/0"

set interfaces ge-0/0/1 gigether-options 802.3ad ae10

4. Commit all changes

commit

Verification and sample output:

Server1 = 192.168.8.20

Server2 = 192.16 8.8.21

Check Port-channel:

user1@Juniper-Router-re0> show lacp interfaces ae10

Aggregated interface: ae10

    LACP state:       Role   Exp   Def  Dist  Col  Syn  Aggr  Timeout  Activity

      ge-0/0/0     Actor    No    No   Yes  Yes  Yes   Yes     Slow    Active 

      ge-0/0/0     Partner    No    No   Yes  Yes  Yes   Yes     Slow    Active

      ge-0/0/1    Actor    No    No   Yes  Yes  Yes   Yes     Slow    Active

      ge-0/0/1    Partner    No    No   Yes  Yes  Yes   Yes     Slow    Active

Check Vlan:

Routing instance        VLAN name             Tag          Interfaces

default-switch          VLAN-100              100

Verify the traffic:

monitor interface ae10.0

monitor interface ge-0/0/0

monitor interface ge-0/0/1
