Sush, Are you thinking of rate-limiting or traffic shaping ? I'd expect rate-limiting of bursty traffic to lose some packets irrespective of the L3 hardware/CPU capacity -- Rafi ## On 2002-07-15 23:57 -0400 Sush Bhattarai typed: SB SB Might want to query your provider as to where

: A cisco ping is not bursty, to the extent of hundreds of mb/s. Also, cisco : ping doesn't offer 4,000 pings/sec. No, but you can start 6 simultaneous sessions to the router and have 5 of them pinging the other side of the circuit while looking at the 6th session to watch for traffic

I may be missing something but.. presumably their rate-limiting involves some form of queuing/buffering.. in which case assuming the ping is the only thing occuring, when the rate hits the limit it will queue, delay and slow down the echo/reply and no packets should be lost? on the other

I would still contend that the number 1 issue is how you do express the policy to the routing code. One could potentially attempt to recognise the primary key is a route-map/policy-statement and compile it as you suggest. It is an idea that ends up being tossed up in the air frequently,

Hello, I've pretty much always assumed that what a switch reported as a status regarding the link of a node was the actual status of the line to be the case. However, when I I think that there is no such thing as the actual status of the line. Each end of the cable has a status, either
