ifInDiscards counter

[crocodanser]

Hi all,
I monitor the ifInDiscards counter of my cisco switch. This counter is occasionally incremented. I saw this counter is incremeted when there isn't enough space in the buffer.

How can i view and resolve this problem?

Thx a lot
Best regards,
Olivier

Buffer drops are a normal part of switching - your only response would be to upgrade the switch to one capable of higher throughput.

What kind of switch is it?

It's an old switch, not critical.

So does this counter says to us that we must upgrade our devices?

Unless they are incrementing all the time and rapidly don't worry about it .

Yes, a newer switch would have a faster backplane and bigger buffers, meaning less chance of having buffer drops.
