Can't ping Wifi Access Points on one vlan from client on another vlan

[cre8toruk]

Hi All,

I've configured a port on my POE switch as a trunk port assigned it the relevant VLAN's that it should host traffic for and I've configured the AP with an IP address in the management VLAN - 192.168.254.146.

I can ping the ip address of the AP from any of the switches (all in the same VLAN and subnet perhaps the clue there) but whilst I can ping all of the switches on the same subnet from a client on a completely different subnet I'm unable to ping the access point. Consequently I'm not able to get it working on the wifi controller server (also on a different subnet). Any ideas ?

The AP's port looks like this;

interface gigabitethernet5
 description Wifi-AP
 switchport trunk allowed vlan add 101-103,190
 switchport trunk native vlan 254

AP: 192.168.254.146 (vlan 254)

Client: 192.168.200.116 (vlan 200)

Client is connected to an access port on SW3 which has a trunk to SW1
i.e:

interface Port-Channel3
 description CORE-SW1-UPLINK
 spanning-tree link-type point-to-point
 switchport mode trunk
 switchport trunk native vlan 200
 switchport trunk allowed vlan 200,254
 macro description switch
 !next command is internal.
 macro auto smartport dynamic_type switch

AP is connected to SW2 and has a trunk to SW1

interface Port-channel4
 description CORE-SW2
 spanning-tree link-type point-to-point
 switchport trunk allowed vlan add 10,101-103,190,200,254,400,2122,2126
 macro description "switch   "
 !next command is internal.
 macro auto smartport dynamic_type unknown

I'm sure I'm missing something obvious.. grateful as always for any assistance.

Paul.

Hi Paul,

You have configured a different native vlan per switch. On one switch it is:

switchport trunk native vlan 254

Next switch it is:

switchport trunk native vlan 200

and finally the last switch does not have any native vlan configured which means it is 1.

So, if you want to configure a different vlan than native vlan 1, you would need to configure the same native vlan on all switches. If you want to keep native vlan as vlan 1 (default), than delete the first 2 statements above and just add vlan 254 ad 200 to the trunks.

Sounds to me like the default gateway of the AP is incorrect.

Right, having conversed with Unify and having plugged a new AP into the existing POE switch (which has all the other AP's plugged into it that work) and determining that the same problem exists, they advise that we need to upgrade our controller etc... So something of a red herring I think.... which is good in one way.

thanks for everyone's help with this.
