I have a Catalyst 3750 switch with port-security and bpduguard enabled on all access ports. The bpduguard works perfectly to shutdown ports when switches using STP are connected. The port-security works perfectly to shutdown ports when switches that don't use STP are connected. I am now trying to get the same behavior from the switch ports when a SOHO NAT router is connected, examples being Linksys or DLink access points. Any ideas?
Here are the settings on the interface:
switchport mode access
switchport port-security aging time 2
switchport port-security aging type inactivity
spanning-tree bpduguard enable
