Interface traffic details

[cjtucker1976]

how can I check the traffic on a serial interface to be sure that it is not overloaded? i having an issue with an application not working over our WAN connection. Thanks

 

[chipk]

show interface ser0/0 (or whatever the interface number is).

Look for the following lines:

reliability
input/output queues
input and output rates
Also look for errors (input, CRC, output, etc.).

Or...you could just post the show interface results here...

 

[cjtucker1976]

here is it- from your expertise, does everything look ok?

Is it a full DS3?

 

[cjtucker1976]

yes
here is the interface info:

5 minute input rate 26466000 bits/sec, 2452 packets/sec
5 minute output rate 1000 bits/sec, 4 packets/sec

If the app is depending on return traffic, this could be a problem...also, 3 resets.

The second post is even worse...post a config.

[vipergg]

All your traffic is coming in and hardly anything going out , strange traffic pattern . While a little busy it should not cause any major problems , you still have a lot of headroom left .

 

[burtsbees]

viper---this is his second post...

5 minute input rate 26464000 bits/sec, 2450 packets/sec
5 minute output rate 0 bits/sec, 1 packets/sec

only 1 packet per sec...

Burt

 

[chipk]

I'd post the whole config.

Do you have the interface stats and config from the other side as well? This is a point-to-point, right?

 

[cjtucker1976]

This is a point-to-point here is the config from the router that I need to send the video stream.

Huh, no errors, and while the really high traffic going in one direction and not the other is unusual, I'm thinking the problem could be in the application. What are you using to encode/stream/decode? Have you tried streaming to a location on your local network to rule out any problems with the video?
