RE: HSRP + Port Security

Hi Rajakumar,

I would definitely change the standby mac-address on both routers to use
different mac-address each one of them.

Example:

R1:
Int fa0/0
Standby 1 mac-address 0000.0000.0001
Standby 1 ip address xx.xx.xx.xx
Standby 1 preempt

R2:
Int fa0/0
Standby 1 mac-address 0000.0000.0002
Standby 1 ip address xx.xx.xx.xx
Standby 1 preempt

On the switches sides, manually configure the new mac-address entries of the
HSRP.

Asunto: HSRP + Port Security

Hello,

I know the following methods to enable port-security on interfaces, which
are connected to routers where HSRP is configured.

Options 1:

switchport port-security

switchport port-security maximum 2

Option 2

Standby use-bia

switchport port-security

switchport port-security maximum 1

However instead of using the above options, I am trying the following since
my requirement is to retain the mac addresses when a switch reloads. I get
duplicate mac-address error message on the switch interface where Passive
router is connected.

SW1

switchport port-security

switchport port-security maximum 2

switchport port-security mac-address <Active router MAC>

switchport port-security mac-address <Virtual mac-address>

SW2

switchport port-security

switchport port-security maximum 2

switchport port-security mac-address <Passive router MAC>

switchport port-security mac-address <Virtual mac-address>

Duplicate mac-address found error message. How to resolve the above issue?

Thanks
