Detection of Wireless Access Points

[fbreeze]

We are rebuilding a very large airport enterprise network with Cisco 6509's in core and distribution and stacks of 3500's at the edges. We have started seeing quite a few cases of user installed 802.11b wireless access points which violates network security. I haven't been able to find any reasonable method of detecting an attached access point, shutting the port on the 3500 down and generating an SNMP trap. Any ideas or plans on the horizon?

Thanks... Frank Breeze

Hi Frank,

I would suggest that you check the MAC prefix for this type of device and put a filter in your routers to detect it and trigger a trap. You can then investigate and close the port if necessary. Another alternative would be to lock all unused ports and lock lve ports to a specfic ethernet address this is secure but a bit labour intensive.
