Any update Jahanzeb ?

Jahanzeb,

Jahanzeb,

Do the following:
Before you connect the printer on the network, see the MAC table of the switch and the ARP table of your network Core if the MAC the new printer is learned.
If so, try to locate the interface where the device with this MAC is connected.

Commands that can help

SWITCH # show mac address-table | include 0000.aaaa.bbbb

CORE # show ip arp | include 0000.aaaa.bbbb

CORE # traceroute mac 0000.aaaa.bbbb 0000.aaaa.bbbb

Do not forget that when you

Do not forget that when you enable port-security, some parameters are implicit. See the defaults parametres bellow (For see it, run the command show run all | sec [interface] ):

switchport port-security maximum 1
switchport port-security maximum 65535 vlan
switchport port-security maximum 65535 vlan access
switchport port-security maximum 65535 vlan voice
switchport port-security
switchport port-security aging time 0
switchport port-security violation shutdown
switchport port-security aging type absolute
switchport port-security limit rate invalid-source-mac 10
no switchport port-security mac-address sticky
no switchport port-security aging static

You can see the subject is disabling interface with the following command

switch#show port-security interface fa0/1
