I've just configured the following port on my 3560G switch:
description Link Router (2Mbit Connection)
switchport trunk encapsulation dot1q
switchport trunk native vlan 10
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust dscp
auto qos voip trust
no mdix auto
The strange thing is that this port shows up in vlan 1 when I run "sh vlan br"
1 default active Fa0/48
Could someone please tell me why that is, even though the native vlan is set to 10?
Because it is not running as a trunk link. I have just done the same thing and when i shutdown the port it shows up in vlan 1.
If the port was up and running and functioning as a trunk then when you run "sh vlan brief" you won't see it attached to any vlan.
The native vlan is only the vlan that traffic will be sent untagged for. Until that port is functioning as a trunk it will remain allocated to the default vlan (unless you change it) which is vlan 1.
