We have SLA configured for failover from primary to DBU on Cisco 871. There are about 170 sites with the same config. We are experienceing problems on one site.
Partial Config is as below
ip sla 1 icmp-echo 220.127.116.11 source-interface FastEthernet4 timeout 10000 threshold 1000 frequency 30 ip sla schedule 1 life forever start-time now
track 10 rtr 1 reachability delay down 180 up 3
Below are SLA and track stats.
Round Trip Time (RTT) for Index 1 Latest RTT: NoConnection/Busy/Timeout Latest operation start time: *08:15:36.158 UTC Tue Jun 18 2002 Latest operation return code: Timeout Number of successes: 0 Number of failures: 53 Operation time to live: Forever
Track 10 Response Time Reporter 1 reachability Reachability is Down 1 change, last change 13:28:59 Delay up 3 secs, down 180 secs Latest operation return code: Timeout
Track remains down no matter what. We have verified primary link to be up and have verified that Cisco uses primary link for all traffic. When dug a little further, we noticed that the first ping to 18.104.22.168 always times out.
ping 22.214.171.124 sou fa 4
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 126.96.36.199, timeout is 2 seconds: Packet sent with a source address of 188.8.131.52 .!!!! Success rate is 80 percent (4/5), round-trip min/avg/max = 152/168/192 ms
Tha above behavior is seem for all external IP Addresses. With first ping timing out all the time and SLA's inability (as far as I know) to retry leaves track in down status.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
