Outbound Network Queue

[Stojcevski Dejan]

Hi,
I have one rp4440 box with several LAN cards. Some of them are 100MB and the build in ones are 1GB.
With Glance I am measuring a Outbound Network Queue on the 1GB PPA of 6 or more all the time!
On other boxes I have, (only 100BM LANs) the same queue is 0 all the time. LAN cards are connected to 10/100MB switches.
I am attaching the output from lanadmin command for that PPA.

How do you use this card?? For what purpose??

[Stojcevski Dejan]

This is the main card trough which all the traffic is handled. Other cards are stand by (MC/SG). Same config I have in other boxes (primary/standby cards) but ther out queue is 0 all the time.

There is a lanshow tool that will collect some data about queues. Also if card is being used heavily, then queue will be high.

For data flowing through card, see packets going through it. glance metric bynet will be helpful in this regard.

Also, check patches.

While that NIC may be a Gigabit NIC from the speed line in the lanadmin output it is only running at 100Mbit, so I could rather easily see it having a non-trivial outbound queue length.

On the plus side, there do not seem to be any outbound drops or other errors at the NIC level.

You can take a couple lanadmin -g mibstats snapshots, saved to files and pass them througyh beforeafter to get how much data was sent over that interval. ftp://ftp.cup.hp.com/dist/networking/tools/
