hello

we got 20 access switches 2960 and 1 core 4500 catalyst series. how to restrict connecting small switches to user access port on Access switches by users.  Is there a way to identify from switch console if a printer is connected to access port.

cheers

No.

how to restrict connecting small switches to user access port on Access switches by users.

Enable BPDU Guard on the access ports.

Hello

You should also think about layer1 devices such as hubs:

int range fa / gig x/x -xxx
switchport host
spanning-tree bpduguard enable
switchport port-security aging type inactivity
switchport port-security violation restrict/shutdown
switchport port-security maximum 3
udld port aggressive
spanning-tree guard loop
exit

errdisable recovery cause psecure-violation
errdisable recovery cause udld
errdisable recovery cause link-flap
errdisable recovery cause loopback
