port security

Is it possible to map 1 MAC address to all ports using port security?

Re: port security

YES, it is possible

eg;

switch1 (enable) set port security 3/1 enable 00-00-00-00-00-01

Port 3/2 port security enabled with 00-00-00-00-00-01 as the secure mac address

switch1 (enable) set port security 3/2 enable 00-00-00-00-00-01

Port 3/2 port security enabled with 00-00-00-00-00-01 as the secure mac address

switch1 (enable) sh port 3/1

Port Name Status Vlan Level Duplex Speed Type

----- ------------------ ---------- ---------- ------ ------ ----- ------------

3/1 notconnect 1 normal half 10 10BaseT

Port Security Secure-Src-Addr Last-Src-Addr Shutdown Trap

----- -------- ----------------- ----------------- -------- --------

3/1 enabled 00-00-00-00-00-01 No disabled

Port Broadcast-Limit Broadcast-Drop

-------- --------------- --------------

3/1 - 0

Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize

----- ---------- ---------- ---------- ---------- ---------

3/1 0 0 0 0 0

Port Single-Col Multi-Coll Late-Coll Excess-Col Carri-Sen Runts Giants

----- ---------- ---------- ---------- ---------- --------- --------- ---------

3/1 0 0 0 0 0 0 0

Re: port security

I thought it was just that simple also. The problem is when I move to the second port, port 3/2 for example, I receive the following message "Mac address enable already configured for port 3/1." Any suggestions?
