Pix 520 Ping Packet Loss.

Unanswered Question

Feb 13, 2002, 2:40pm Pacific

I have a PIX 520 version 6.1.2 outside interface that is getting packet loss. I was wondering if that is by design or not. Is there a way for me to specify how the PIX responds to ping requests other than of course allowing it or not?


I have ICMP on and can ping to the inside and outside and from the outside in. I am just wondering if there is a problem with the pix.


To test the situation I put a laptop in place of the pix and there was no packet loss. Once I put the pix back I got packet loss.


I have a cabinet at XO and they did exhaustive tests to see if the packet loss is there problem and it really seems that it is not.


CPU usage is at 3% so it does seem overloaded.


Traffic is as follows:

outside:

received (in 8946.060 secs):

5000655 packets 582517334 bytes

78 pkts/sec 65114 bytes/sec

transmitted (in 8946.060 secs):

5450081 packets 4280507727 bytes

129 pkts/sec 478479 bytes/sec

inside:

received (in 8946.060 secs):

5476316 packets 4917120 bytes

132 pkts/sec 69 bytes/sec

transmitted (in 8946.060 secs):

4546533 packets 555782637 bytes

28 pkts/sec 62125 bytes/sec



Thanks in advance,

Here is the config.


Could it be that the pix is busted?

Their might be a duplex mode mismatch. Try to set the interface to either full or half duplex instead of auto

Well I think I have the answer.


You will like this one.


I opened a trouble ticket with my ISP where all of this is collocated (XO), and they finally said the problem was the pix.


That's when I started asking you guys. Well, it turns out that they put a 5 megabyte cap on all lines. I am doing, at least 10 megs at peak hours, which caused the problem.


So they are removing the cap. I will see if that solves the ping issue.


Again thanks for your help. Wish me luck with the removal of the cap. If that isn't it I might have to replace the cards on the pix.


Also, I did adjust the duplex to 100full and problem was still there. Thanks for the suggestion there, I also verified that the ISP’s switch was outputting at 100full and they were.
