[c-nsp] "Total output drops" - congestion ? - 7200-VXR

2008-07-15 Thread Wilkinson, Alex
Hi all, I am having problems with a particular device going down every 3-4 days. The switchport for which this device is connected to is telling me it is having a lot of "output drops" e.g. Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 13342805 I 'suspect' that these

What is the configuration of that interface and can you provide a 'sh int' between two drop periods? On Wed, Jul 16, 2008 at 02:22:31PM +0800, Wilkinson, Alex wrote: > Hi all, > > I am having problems with a particular device going down every 3-4 days. > The switchport for which this device is co

Have you tried 'hold-queue ...' command. This may resolves your problem. On Wed, Jul 16, 2008 at 11:22 AM, Wilkinson, Alex <[EMAIL PROTECTED]> wrote: > Hi all, > > I am having problems with a particular device going down every 3-4 days. > The switchport for which this device is connected to is te

It is inadvisable to increase the output hold-queue as far as I am aware, this could cause packets to be delayed on egress which could cause TCP timeouts. Dave. Farhan Jaffer wrote: > Have you tried 'hold-queue ...' command. This may resolves your problem. > > > On Wed, Jul 16, 2008 at 11:22 AM

Hi Guys, This really depends on the speed of the Interface and what is connected on the other side. We had a Serial Satellite link of 5M, which was never running higher than 4.5M - due to regular bursty traffic. After increasing the queue (fair-queue 320 256 0) the link now does about 4.9M, w

Hard to say without more data. What is connected to the FE port shouldn't have anything to do with the ATM link status. On Thu, Jul 17, 2008 at 08:32:34AM +0800, Wilkinson, Alex wrote: > 0n Wed, Jul 16, 2008 at 07:28:05AM -0400, Rodney Dunn wrote: > > >What is the configuration of that
