Hi guys

  I have a design where I have three layer 2 switches connected to a layer 3 switch. The layer 2 switches each have vlans (10,20,30) and I can communicate across vlans fine. I am trying to add redundancy to the design by adding a standby layer 3 switch.

This is the current configuration of the primary layer 3 thus far:

The problem is when I go into the layer 3 switch and set up tracking I am unable to add a decrement to Fa0/1, 2, or 3 connection on the layer 3 switch;

CORE/DIST-SW(config)#interface vlan 10

CORE/DIST-SW(config-if)#standby 10 ip 10.0.1.1

%HSRP-6-STATECHANGE: Vlan10 Grp 10 state Speak -> Standby

%HSRP-6-STATECHANGE: Vlan10 Grp 10 state Standby -> Active

CORE/DIST-SW(config-if)#standby 10 priority 110

CORE/DIST-SW(config-if)#standby 10 track fa0/1 ?

<cr>

CORE/DIST-SW(config-if)#standby 10 track fa0/1 20

^

% Invalid input detected at '^' marker.

CORE/DIST-SW(config-if)#

Can anyone suggest what is going wrong? Thanks

Hi

i dont think there's anything wrong just the software switch doesn't have that ability

thats a older switch FE it just doesn't have the syntax

#

xxxxxxxxxxx(config-if)#standby track GigabitEthernet2/8/37 ?
  <1-255>  Decrement value

just set one side as priority 110 and the other as 105

Thanks for the reply, should I change the switch or just set a priority and dont track?

[Mark Malone]

I wouldn't change the switch , I would just use it without the decrement syntax but you can still use track command

[Ammit]

Ah yes thank you now works as planned
