Hi!
We have an ASA with 2 ISP's and sla monitor configured. And it works great if the first channel fully fails.
But in the case of packet loss on the first channel, we are getting the channel flapping.
sla monitor 1
type echo protocol ipIcmpEcho 8.8.8.8 interface outside
num-packets 5
timeout 1000
frequency 60
So, if the ping process fails, we are going to the secondary channel.
But as I understand sla monitor operation, we are sending 5 packets to Google's public DNS with one second interval. So, if one of this packets pass, the channel considered as active and we are returning to the main channel.
How should we set up the ASA so that the first unstable channel doesn't cause channel flapping?
Is there a procedure to verify, that the main channel not only returned, but it's become stable?
May be is there a way to set the successful sla criteria as all-of-num-packets instead of one-of-num-packets?
Thanks.
