configure port to allow multiple vlans but untag one specific vlan traffic. also set up that specific vlan as default vlan of that port?

Hello,

I need some help to make some changes to a X465 switch configured by someone else. I need to configure a port to allow multiple vlans but untag one specific vlan traffic. Also set up that specific vlan as default vlan of that port? This is basically set up trunk port to allow multiple vlans and set up one native vlan in Cisco world? Can someone please show me how to achieve this in EXOS?

Thank you,

John

If VLAN red is your untagged VLAN, and VLANs blue and purple are your tagged VLANs, and you want them on port 9, then use this config:

configure vlan red add port 9 untagged

configure vlan blue add port 9 tagged

configure vlan purple add port 9 tagged

You may need to configure vlan default delete port 9 before you can add red as untagged since you can only have one untagged VLAN per port.

Thank you Drew for your quick response.

One more question, how can I set up vlan red as the default vlan for that port (i.e, use vlan red’s vid as the default vid)? In ERS, I use untagpvidonly to configure AP port.

Thank you,

John

Hi John,

If you add the port as untagged, it will be the “default” VLAN. The VLAN tag/ID won’t matter in EXOS if you set it that way.
