Port Security on a 877 router ?

Unanswered Question
Oct 11th, 2007

Stuck on this one.

The 877 has a 4 prot managed switch.

How / where is the port security?

Desired to lock 1 mac address to a switchport and admin down on exception.


Lost in the documentation.

I have this problem too.

Since this is not a higher end catalyst with the switchport security-xxx commands available, I believe this work-around comes close to the requirement, exception admin down.

config t

Interface vlan1

arp authorized

! disables dynamic learning arp address for the vlan


arp 0060.9714.9574 arpa

! create a static arp entry for the known host

Your thoughts and comments welcome.

4 port managed switch on router877 is a very bare bones switch and does not support any advanced layer2 functions. The only features those ports support are VLANS (dot1q only) and auto-mdix.

Here is the datasheet for the router which lists all the features of this Router and port-security is not one of them.
