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

      ge-0/0/1    Partner    No    No   Yes  Yes  Yes   Yes     Slow    Active
Check Vlan:
user1@Juniper-Router-re0> show vlans VLAN-8
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
