C2960TTL multiple Trunk ports with same VLAN

(OP)
Dear support/ Gurus.
I configured my C2960 TTL port-1 as a trunk with allowed VLAN 1,16,17 connected with WiFi AP DAP-2695
then I configured my C2960 TTL port-2 as a trunk with allowed VLAN 1,16,17 connected with my 2nd WiFi AP DAP-2695
then I configured my C2960 TTL port 24 as a trunk with allowed VLAN 1,16,17 connected with my DHCP server configured LAN interface with 802.1Q VLAN 1, 16, 17 TAGGING.

interface FastEthernet0/1
description ToWiFi1
switchport trunk allowed vlan 1,16,17
switchport mode trunk

interface FastEthernet0/2
description ToWiFi2
switchport trunk allowed vlan 1,16,17
switchport mode trunk

RE: C2960TTL multiple Trunk ports with same VLAN

Point number 1:

Why does anyone use VLAN1 for anything? All ports on an "out of the box" switch are automatically assigned to VLAN1. This is a massive security risk for any organization. Shutdown VLAN 1 and create a new VLAN for management.

Okay, from the perspective of trunked ports, I see no issue here with the configuration. Have you had a look at the actual ports on the switch to see what is happening there? Are they showing as "up, up"? Ensure that there are no errors on the ports (CRC's could be a cause).....

I'm not sure about the multiple SSiD's......

Check the ports on the switch..... show int ????? etc etc.....

Check any log files on the WLC as well.....
