hi all,
i'm monitoring a 2951 router for high usage and latency. i've observed rxload is always 255/255.
would like to know if this is some kinda cosmetic bug? TIA!

Enable IP Netflow so you can determine WTF is going on and where the traffic is coming from.

You may need to check the traffic passing on this is genuine traffic. If so hardware upgrade could resolve this as the router is not capable of handling this huge traffic.
