Trunk Port issue 3560

Hello,

I have a cisco 3560 L3 switch. The 4 GBIC slots are configured as trunks and are behaving as needed. However, this is a 48 port switch and have exhausted our ports so would like to attach another 24 port to it. I am trying to configure port 48  as a trunk and the following has already been configured:

interface FastEthernet0/48

switchport trunk encapsulation dot1q

switchport mode trunk

no ip address

srr-queue bandwidth share 10 10 60 20

srr-queue bandwidth shape  10  0  0  0

mls qos trust cos

mdix auto

auto qos voip trust

This is the interface configuration of a working trunk port:

interface GigabitEthernet0/1

switchport trunk encapsulation dot1q

switchport mode trunk

no ip address

srr-queue bandwidth share 10 10 60 20

srr-queue bandwidth shape  10  0  0  0

mls qos trust cos

auto qos voip trust

However, if I view the vlan table, I see that port 48 is part of the default vlan while the other trunk ports are not. What am I missing here?

VLAN Name                             Status    Ports

---- -------------------------------- --------- ----------------------------

1    default                          active    Fa0/3, Fa0/4, Fa0/6, Fa0/48

Thanks!

Hi Max,

it beacuse probably interface fastEthernet0/48 has not link and is no up.


Trunk ports that are not connected appear by default in vlan 1 and also appear in the output of the show vlan.

Best Regards,

Jan
