Juniper switch Basic Configuration Commands

Hello fellow blog reader, after long gap I'm going to write this thread regarding the basic Juniper command and configuration. I try to include as much as troubleshooting/configuration command during day to day work.
I would like to thank to Srijan pointing the error on LACP command.

1. Set username for login
root@jpudasaini#set system root-authentication encrypted-password
New password:
Retype new password:

root@jpudasaini#set system login user jay full-name jaypudasaini uid 400 class super-user authentication encrypted-password


2. Hostname configuration.
root@switch#set system host-name jpudasaini
root@jpudasaini#

3. Set Tacplus authentication for juniper switch.
root@jpudasaini# set system authentication-order tacplus
root@jpudasaini# set system authentication-order password
root@jpudasaini# set system root-authentication encrypted-password "you password here"
root@jpudasaini# set system tacplus-server 10.10.10.10(your tacplus server IP) secret "your server password here"
root@jpudasaini#set system tacplus-options service-name test

4. Configuration VLAN(Group)
root@jpudasaini#set vlans Cust-Fiber vlan-id 500-550
root@jpudasaini#set vlans Cust-Wireless vlan-id 551-575
    single vlan
root@jpudasaini#set vlans Cust-A vland-id 25

5. Trunk Port Configuration
root@jpudasaini#set interfaces ge-0/0/9 description connect-to-sw2
root@jpudasaini#set interfaces ge-0/0/9 unit 0 family ethernet-switching port-mode trunk
root@jpudasaini#set interfaces ge-0/0/9 unit 0 family ethernet-switching vlan members Cust-Fiber

6. Access Port Configuration
root@jpudasaini#set interfaces ge-0/0/0 description Link-to-sw3
root@jpudasaini#set interfaces ge-0/0/0 unit 0 family ethernet-switching port-mode access
root@jpudasaini#set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members 25

7. Port Channel Configuration
root@jpudasaini#set chassis aggregated-devices ethernet device-count 10
root@jpudasaini#set interfaces ae0 description TR-2-Jpudasaini-Sw2
root@jpudasaini#set interfaces ae0 aggregated-ether-options lacp active
root@jpudasaini#set interfaces ae0 unit 0 family ethernet-switching port-mode trunk
root@jpudasaini#set interfaces ae0 unit 0 family ethernet-switching vlan members Cust-Fiber
root@jpudasaini#set interfaces ae0 unit 0 family ethernet-switching vlan members Cust-Wireless

8. Port Channel Assign to the Physical Port
root@jpudasaini#set interfaces ge-0/0/16 description test-sw1
root@jpudasaini#set interfaces ge-0/0/16 ether-options 802.3ad ae0
root@jpudasaini#set interfaces ge-0/0/17 description test-sw1
root@jpudasaini#set interfaces ge-0/0/17 ether-options 802.3ad ae0

9. Configuration management IP for switch.
root@jpudasaini#set interfaces vlan unit 20 family inet address 10.10.10.11/24

10. Configuration snmp.
root@jpudasaini#set snmp name Test-SNMP
root@jpudasaini#set snmp description test-sw2
root@jpudasaini#set snmp location "Jpudasaini-NOC"
root@jpudasaini#set snmp contact "system@jpudasaini.com.np"
root@jpudasaini#set snmp client-list list0 10.10.10.0/24
root@jpudasaini#set snmp community ax3R5vgW authorization read-only
root@jpudasaini#set snmp community ax3R5vgW client-list-name jpudasaini

11. Enable LLDP
root@jpudasaini# set protocols lldp interface all
root@jpudasaini#set protocols lldp-med interface all

12. Configure port as L3
root@jpudasaini#set interface ge-0/0/23 unit 0 family ethernet-switching port-mode trunk
root@jpudasaini#set interface ge-0/0/23 unit 0 family ethernet-switching vlan member 25
root@jpudasaini#set vlan Mgmt vlan-id 25
root@jpudasaini#set vlan Mgmt l3-interface vlan.25
root@jpudasaini#set interface vlan.250 family inet address xxx.xxx.xxx.xxx

13.Rate Limit
 Configure the policer

root@jpudasaini# set firewall policer Policer_2M if-exceeding bandwidth-limit 1M
root@jpudasaini# set firewall policer Policer_2M if-exceeding burst-size-limit 2k
root@jpudasaini# set firewall policer Policer_2M then discard

Configure the firewall filter

root@jpudasaini# set firewall family ethernet-switching filter Limit term 1 then accept
root@jpudasaini# set firewall family ethernet-switching filter Limit term 1 then policer Poicer_2M

Apply filter on interface (can be any interface as required)

root@jpudasaini# set interface ge-0/0/24.0 family ethernet-switching filter input Limit

Note: Remember that EX series switches apply rate limit only on ingress.

  1. you should set number of aggregate ether-channel before creating LACP links with CMD.
    " set chassis aggregated-devices ethernet device-count 10".
