Switching

Hi All,

      This is a simple question but I cant find the answer anywhere.  How can I view the status of my trunk ports on an EX switch.  Or even how to I view what ports are trunking

Cisco has the show int trunk commands which works great.

anyone have the answer?

Thanks!

Hi,

show interfaces aeo terse:

The output confirms that the ae0 link is up and shows the family and IP address
assigned to this link.

If you are using LACP:

show lacp interfaces xe-0/1/0

Hi,

you could use Op script (attached). Please consider following disclaimer BEFORE you start using scripts (BEFORE USING JUNOS SCRIPTS PLEASE READ THIS..., http://forums.juniper.net/jnet/board/message?board.id=JUNOS&thread.id=12).

Steps how to use it:

1) Upload  show-trunk.slax to /var/db/scripts/op/

2) From configure mode: "set system scripts op file show-trunk.slax"

3) From operational mode: op show-trunk OR from configuration mode: run op show-trunk

Output would look like:

root@VC2> op show-trunk
Interface    State    VLAN Member             Blocked       Description
ae0          down     blue                    RTG Blocked  
                      vlan200                 RTG Blocked
                      red                     RTG Blocked
                      yellow                  RTG Blocked
ae1          up       blue                    unblocked    
                      vlan200                 unblocked  
                      red                     unblocked  
                      yellow                  unblocked  
ge-0/0/20    down    
ge-0/0/21    down     blue                    unblocked    
ge-1/0/0     up       vlan100                 unblocked    
                      vlan200                 unblocked  
                      vlan300                 unblocked

Do not forget "commit" before you go to step 3.

Kind Regards

show ethernet-switching interfaces detail | match Trunk

Will give you a simple list of trunking ports

ccb@BSMT-stack> show ethernet-switching interfaces detail | match Trunk
Interface: ge-0/0/0.0, Index: 66, State: up, Port mode: Trunk
Interface: ge-0/1/3.0, Index: 114, State: up, Port mode: Trunk
Interface: ge-2/1/3.0, Index: 259, State: up, Port mode: Trunk
Interface: ge-3/0/46.0, Index: 161, State: down, Port mode: Trunk

{master:1}
ccb@BSMT-stack>

This vc has four trunking ports

Then you could use show ethernet-switching interfaces detail <interface-name> to get more info

Hi,

Slight variation on the answer above that gives you a little more info:

> show ethernet-switching interfaces | except untagged

[edit interfaces]
root@switch# run show ethernet-switching interfaces | except untagged
Interface    State  VLAN members        Tag   Tagging  Blocking
ge-0/0/0.0    up     mgt-150                    150     tagged   unblocked
                                tor-1751                    1751   tagged   unblocked
ge-0/0/21.0  up     vlan100                     100     tagged   unblocked

Hope it helps 🙂

Ben.
