Bennettj,
We too have some Juniper switches, and I plan to support them as soon as I get some time. Others have expressed an interest in HP switch support, but I do not have access to any of those at the moment.
The next release of NetDB v1.7 will include a new scraper, and I hope to be able to add extended vendor support to it next. Of course I will always accept patches or help if...
Bennettj,
I'm going to release a new version in the next few days which should resolve all static mac address entry problems. It seems when any port security or private vlans are configured, the mac address table entries for those entries are static rather than dynamic. Check back soon for a fix.
Jonathan.
