The ever changing IP SLA/RTR Tracking operation

[mmedwid]

I just tested IP SLA with tracking on a 3750 12.2(46)SE.  And the configuration was simple enough and tested

fine for redundant static routing:

ip sla 10

icmp-echo 10.10.99.2

ip sla schedule 10 life forever start-time now

track 401 rtr 10

Then I tried to do the same on a 3560 switch running 12.2(55)SE3.  ip sla went in fine.  But when I went

to put in the track I was presented with "list boolean and" (for example) after the track and the identifier.

I tossed in the ip sla "10" as the object.  But shopw track shows the boolean AND as down.  I don't

get why the track feature is different in two switches so close in IOS version.  How do I get the 3560

to track the ip sla as my 3750 does?  Thanks.

ip sla 10

icmp-echo 10.10.7.1

timeout 2000

frequency 3

ip sla schedule 10 life forever start-time now

track 471 list boolean and

object 10

!

c3560-1#sho track

Track 471

  List boolean and

  Boolean AND is Down

    1 change, last change 00:06:51

    object 10 (Undefined)

Hi,

Boolean AND / OR is generally used when you have 2 or more objects by which you want to track.

Try changing boolean expression to OR instead of AND.

Secondly solution would be go for RTR Reachability or state in track.

This is what worked:

c3560-1(config)#track 471 ip sla 10

mccx-c3560-1#show track

Track 471

  IP SLA 10 state

  State is Up

    1 change, last change 00:00:13

  Latest operation return code: OK

  Latest RTT (millisecs) 7

Yeah,

I forgot to mention that it will be IP SLA and not RTR.

HTH,
