What model and software revision are you using? Are you looking for
aggregate stats or packet-by-packet monitoring?

Port utilization - Bandwidth monitoring tool based on SNMP (ie
SolarWinds)
VLAN Monitoring - Port/VLAN Span with Sniffer
Source/Destination Traffic - Turn up netflow on router or switched
virtual interface of that vlan, and log to a netflow collection server
(fluke, solarwinds, cisco)

There are free options for most of the above, you'll just have to surf
and find them or find trials if you don't have necessary capital.

Some possibilities:

root@charles-laptop:~# apt-cache search netflow
flow-tools - collects and processes NetFlow data
flow-tools-dev - development files for flow-tools
fprobe - export captured traffic to remote NetFlow Collector
fprobe-ng - export captured traffic to remote NetFlow Collector (meta)
fprobe-ulog - export captured traffic to remote NetFlow Collector (ULOG
version)
libcflow-perl - perl module for analyzing raw IP flow files written by
cflowd
nfdump - netflow capture daemon
pmacct - promiscuous mode traffic accountant
root@charles-laptop:~#

This is on Ubuntu 8.04.

Might be of use to you.
