It's not in MIB-2 but it is in RMON2 (RFC2021) and, by extension, SMON
(RFC2613) and, as you say, might be provided in a proprietary MIB. An
alternative might be that the information could be in the firewall logs
and you might be able to get it from that (although it may not be
available as frequently as every 5 minutes by default).
