Definitely, you can use vlan map with port security. The only restriction
with vlan map is port access list. A catalyst switch that has layer 2 input
port access list can not have either vlan map or input router access list.
I will test your idea tonight and let you know tomorrow.

I wonder could you use a vlan-access-map in conjunction with port security
Put port in vlax x
Add port security for the mac-address you want,
And the add a vlan-access-map for this vlan stating traffic only from the
particular ip address you want,
This might achieve the desired solution.
Just throwing up ideas..

I clear the arp cache before changeing the ip address. Didn't help.

Hi Guys,
Got a scenario on 3550. Only allow packet with mac-address 1234.1234.1234
and ip address 1.1.1.1 to access port fa0/1. Cannot use L2 or L3 access
list. I though of using switchport port-security and arp static mapping as
follow:
interface FastEthernet0/1
switchport mode access
switchport port-security
switchport port-security mac-address 1234.1234.1234
arp 1.1.1.1 1234.1234.1234 ARPA
I am able to ping to 1.1.1.1. But if I change the host to 1.1.1.2, I am
still able to ping to 1.1.1.2. This would go against the condition only the
host with 1.1.1.1 is allowed. I saw some thread similar before but can't
find anything in archive. Please help thanks.
Regards
