- Need help on bandwidth management

I've got a remote site connected to the central site for Internet
access via 2 T1s to an ATM network. Voice has been allocated 800k of
this bandwidth, and the rest is data. Network usage at this particular
site has been growing within the past couple of months and at times
bandwidth has been maxed out. I need some way to make sure bandwidth
is allocated fairly. I'd like to be able to add more capacity, but
that's not going to be possible right now.
One of the first things I thought of was unicast storm-control. If I
went this route, I'm not sure what parameters to use. Right now, some
ports are set to an upper limit of 5%, and some are set to 5k pps (the
default value, I believe). This was all set up before I started here,
and I've never really given it much though until this project came
along. It looks like the upstream connection for that site rarely gets
over 450 pps to the central site.
- Is unicast storm-control a good option here, or should I look at
- If I do use it, can someone point me to where I can find some help
on the best settings to use in this particular environment?
Re: Need help on bandwidth management
You didn't specify, but I assume you are looking to use as much of the
bandwidth as possible for data, and utilize any unused voice bandwidth.
If your equipment is capable, you can set the voice vc to "variable
bit-rate - real-time," and the data vc to "available bandwidth." When
there is no voice traffic, the full bandwidth is available for data, and
voice traffic will take only what it needs, up to the maximum configured
