[Devil-Linux-discuss] Limiting/viewing broadcast in tagged trunks

[Aaron M. <aa...@uw...>]

Hi All,

We're using Devil Linux to provide a Quarantine environment as a sub-network 
within the normal one, but we ran into an issue yesterday were extreme 
amounts of broadcast coming from the Quarantine box were causing CPU load 
issues on the Catalyst 6513 core.

The Devil Linux box has a single 100Mbps connection into it with about 3 
dozen vlans tagged on that connection.  When the broadcast starts, we first 
have no way of knowing which of those vlans is causing the issue.  So first 
question would be does anyone know of a way to quickly check out the 
broadcast of the individual vlans and see which is much higher than normal?

Second, does anyone know if there is a way that I can limit broadcast from 
that box (either on a per-vlan basis or as a whole)?
