I'd appreciate if anybody could tell me their experiences configuring 802.1q trunking with other non-cisco switches, specifically extreme summit's, these are 4003's and summit48, any help is greatly appreciated.
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.
Thanks a lot for your help! So the trunk ports (i.e. GB uplinks to cisco core switch) in the summit would need to be tagged for all Vlans (using same number as in cisco switch) to enable vlan traffic to traverse the trunk links?
