Hi.
I'm trying to create trunkports on our Catalyst 2960.
I'm following this guide to configure interface fa0/1
| |
Command |
Purpose |
|---|
Step 1 |
configure terminal |
Enter global configuration mode. |
Step 2 |
interface interface-id |
Specify the port to be configured, and enter interface configuration mode. |
Step 3 |
Switchport mode trunk |
Configure the interface as a VLAN trunk port. |
Step 4 |
switchport trunk allowed vlan {add | all | except | remove} vlan-list
In my case, switchport trunk allowed vlan add 1-2
|
(Optional) Configure the list of VLANs allowed on the trunk.
For explanations about using the add, all, except, and remove keywords, see the command reference for this release.
The vlan-list parameter is either a single VLAN number from 1 to 4094 or a range of VLANs described by two VLAN numbers, the lower one first, separated by a hyphen. Do not enter any spaces between comma-separated VLAN parameters or in hyphen-specified ranges.
All VLANs are allowed by default. |
Step 5 |
end |
Return to privileged EXEC mode. |
Step 6 |
show interfaces interface-id switchport |
Verify your entries in the Trunking VLANs Enabled field of the display. |
Step 7 |
copy running-config startup-config |
(Optional) Save your entries in the configuration file. |
When I run the command show interfaces fa0/1 trunk, I got this result
Port Mode Encapsulation Status Native vlan
Fa0/1 on 802.1q other 500
Port Vlans allowed on trunk
Fa0/1 none
Port Vlans allowed and active in management domain
Fa0/1 none
Port Vlans in spanning tree forwarding state and not pruned
Fa0/1 none
I'm expecting that my vlans that I have allowed, should be listed like this
show interfaces fa0/24 trunk
Port Mode Encapsulation Status Native vlan
Fa0/24 on 802.1q trunking 500
Port Vlans allowed on trunk
Fa0/24 90-95
Port Vlans allowed and active in management domain
Fa0/24 90
Port Vlans in spanning tree forwarding state and not pruned
Fa0/24 90
So why doesn't it work on interface 1 (and 2-4) when it working on interface 24?
