I have two sites linked together via microwave with dialup as backup solution.  I have an IP SLA monitoring the main link and activates the dialup when the link goes down.

Well, my problem is that the SLA errorously sees the main link go down and kicks in the dialup.  BUT just for a few seconds and once it sees the main link up it, of course, drops the dialup.

On both ends, I have increase the timeout from 1000 to 10000 and changed the frequency to 51.  Hoping that prohibit the dialup.  But it hasn’t.

I have added the SLA config for your reference.

This is the far-end RTR

ip sla monitor 11

type echo protocol ipIcmpEcho

timeout 10000

threshold 4

frequency 51

ip sla monitor schedule 11 life forever start-time now

this is the central RTR

ip sla monitor 12

type echo protocol ipIcmpEcho

timeout 10000

threshold 4

frequency 51

ip sla monitor schedule 12 life forever start-time now

I think I need to change the SLA statement but I’m not sure. 

Thanks, Gary
