WS-C2960X-24PS-L vlan problem

[ict3tcsoftware]

Hi,

I've recently upgraded a POE switch from a SF-300-48P to a WS-C2960X-24PS-L.

I have 4 Ruckus APs connected to the POE switch with corporate WiFi on vlan 1 and guest WiFi on vlan 10. On the SF-300 both WiFi networks work. After moving the APs to the C2960X they don't work.

If the switch mode is set to dynamic auto then vlan 1 works and AP responds to pings, the port is reporting as being an access port. If the switch port is set to trunk then the WiFi on vlan 1 still works but vlan 10 doesn't. Also, the AP doesn't respond to pings when the mode set to trunk.

Any help would be greatly appreciated.

Can you post the configuration of the Port to understand the issue

or try below :

interface range GigabitEthernetx/x
switchport mode trunk
switchport trunk native vlan 1
switchport trunk allowed vlan 1,10

Config for the port is:

interface GigabitEthernet1/0/15
switchport trunk allowed vlan 1,10
switchport mode trunk
end

ran your suggested config and the port still shows the config as

interface GigabitEthernet1/0/15
switchport trunk allowed vlan 1,10
switchport mode trunk
end

I assume the switchport trunk native vlan 1 command is implied as it is the default vlan.

yes correct - even you add  native vlan 1 - if implied default it wont show there (no harm adding line)

Hi,

Just thought I'd give a recap of my problem.
I've simplified the set up to have a single AP connected to a C2960X-24PS switch.
The network looks like this.

|ASA5516X |---| C9200L |---|C2960X-24PS|--| AP |

There are 2 SSIDs on the AP:
vlan1 - corp
vlan10 - guest

I've set up a SPAN to see what is coming into the C2960X port.

Port config is:
interface GigabitEthernet1/0/19
switchport trunk allowed vlan 1,10
switchport mode access
speed 1000
duplex full

In access mode, I can access the AP web interface and connect to the corp wifi, everything as it should be.
Wireshark shows traffic from both vlans.

Change the port to a trunk port gives this config
interface GigabitEthernet1/0/19
switchport trunk allowed vlan 1,10
switchport mode trunk
speed 1000
duplex full

In trunk mode access to the AP is lost, corp wifi is lost also.
Guest wifi is now working
Wireshark shows traffic from vlan10 only

Sorry for the long post, but if I had some hair I'd be pulling it out.

Many thanks,
Colin
