0 bits/sec output rate

[snarayanaraju]

Hi 

I am seeing 0 bits/sec output rate whereas the around 26Mbps traffic ingress to the interface. 

What does it indicate? How the return traffic is not showing as output packets?

5 minute input rate 26319000 bits/sec, 3017 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

regards,

it may possible outgoing traffic on another device/ interface.

[snarayanaraju]

Thank you. That makes sense. It is possible in my setup

Any other thought or chances for this situation? thanks

Hello,

I remember there to be a bug in older IOS versions, which one are you running ?

Also, the outgoing traffic rate might be too low to show up in the interface statistics. Try to change the load interval on the interface to 30 and see if that makes a difference:

Router#conf t

Router(config)#int serial0

Router(config-if)#load-interval 30

Can you post the full output of 'show int' ?

Hello,

your input packets (15617780531) exceed the output packets (51845891) by a factor of 300. So there definitely is output traffic, but likely too little to show up in the interface stats. Have you tried yet to set the interface load-interval to 30?

[snarayanaraju]

Looks like the output rate is very low. Even changing the load interval to 30 sec doesnt reflect in "show interface counters". As you noticed there is output packets but it increases at the rate of 1 packet 

Thanks
