Trunking ports to non-cisco switches

The native VLAN is a untagged dot1q VLAN (frames sent/received without 802.1q headers). Some switches let you tag all VLANs (extreme does, and most cisco switches with newer code do). If you use this feature then there isn't really a native VLAN anymore as all traffic is tagged with a VLAN header, but the VLAN number / id's have to match up on connecting switches. Names don't matter.


On the summit, you configure tagged and untagged ports like below.


configure vlan "Default" tag 1

configure vlan "Default" add port 49 untagged

configure vlan "Default" add port 50 untagged


configure vlan "other" tag 10

configure vlan "other" add port 49 tagged

configure vlan "other" add port 50 tagged


Default VLAN is Vlan 1, tagged VLAN is 10.

Port 49 and 50 are untagged (native in cisco speak) for VLAN 1 and tagged for VLAN 10.
