Inaccessible Management Interface

[latitudegroup]

Hey guys,

I might be missing something really obvious here but I've got a number of WAP's, to which the connecting switchport interface is trunked to allow for the support of multiple networks accessible through the WAP SSID's. All SSID's are functioning (SSID's on vlan 1000 / 1234). The management interface for the WAP's is on the native VLAN 1200. However, the IP address is not contactable.

Please find connecting switchport config below...

GBMCWSWI01#show run int gi 1/0/41
Building configuration...

Current configuration : 174 bytes
!
interface GigabitEthernet1/0/41
 description "Cisco WAP LATXXWAP01"
 switchport trunk native vlan 1200
 switchport trunk allowed vlan 1000,1234
 switchport mode trunk
end

This configuration functioned upon our old Dell Powerconnects but not on our 2960's that we've recently replaced the old Dell kit with.

Probably something obvious.

Any assistance appreciated.

Hi there,

You have configured a native vlan correctly on the trunk interface and it will send frames untagged originated from vlan 1200, but you need to allow vlan 1200 as well on the trunk interface.

interface GigabitEthernet1/0/41
 description "Cisco WAP LATXXWAP01"
 switchport trunk native vlan 1200
 switchport trunk allowed vlan 1000,1234,1200
 switchport mode trunk
end

That's done it. Many thanks Cofee!  Really appreciate the assistance.
