Hi every body can any one solve my issue. How to assign the trunk links to to separate vlans. I used this command,
enter the trunk port, then #switchport trunk native vlan 10, is this right or wrong. if it is right? when i enter the command like show vlan brief, the the trunk vlans are not displaying.

How to view the trunk assigned vlans. i am confusing this issue..
Thanks in advance.

Native VLAN 10 means any untagged traffic coming across the trunk should be sent to VLAN 10.

The command you want is sh int trunk

Cat3550#show interfaces trunk

Fa0/17  trunk    802.1q         other      1
Fa0/18  trunk    802.1q         other      1

Fa0/19  trunk    802.1q         other      1

Port      Vlans allowed on trunk Fa0/17     1-4094 Fa0/18     1-4094

Fa0/19     1-4094
