Cisco ASA 5510 running Version 8.0(5) Two routers on separate ports. One works as it should, the other is being finnicky for a completely unknown reason.
ping PORT1 8.8.8.8
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 10/10/10 ms
ping PORT2 8.8.8.8
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
??!!! / ?!!!? / !!!??
Success rate is 60 percent (3/5), round-trip min/avg/max = 20/30/50 ms
It’s always 3/5 but different patterns as shown above. So I figure one of two things could be happening. Either the router behind PORT2 is bad or the cable is bad. So I hooked up a laptop using the same cable and gave it the same IP. It works just fine. No drops, latencies, or anything else.
Could it possibly be the actual port on the ASA? Should I try a different port? Haven’t tried that yet because I find that unlikely. Or could it be the config? Not sure what config sections to post, so please let me know. Both ports are configured exactly the same and I’m not aware of a config that would only let 3 out of 5 packets through. The MTU is the same on both at 1500.
