Network guys...

I'm investigating a 3-6% packet loss on a router on a Etherconnect network,

Customer is seeing "Erratic responses"

Is there a way to check packet loss on the router ? I'm newish to all these commands and the like.

Cheers

Lol, thanks for that xD

What make/model of router?

 

[Stevo_Nimbus_R27]

If it's a Cisco running IOS and the framing on the interface is Ethernet then use the command show interface interface name

The output will show you counters for input and output CRC errors, runts, giants and collisions.

From here you should be able to establish if the router interface is dropping traffic or whether it's somewhere else in the network.

Remove all of the users, no more collisions \o/

If your running a Cisco 2600 or whatever (industry type router)

sh int fa 0/1 (or s 0/0/0) will provide you with a list of info on packet loss and other s**t as mentioned, do you not have Cisco SDM installed im sure that gives you some tools to work with, although i might be wrong, i dont know how to use the GUI very well let alone access it anymore, all about the CLI

Are you running any protocols in particular ?

Is 3 - 6 % not within your "baseline" ?

Cant you tell the customer to f**k off ?

Use a network monitoring tool like Orion (Solar winds) ?
