anyone have experience on query SNMP for switch with VLAN been bridged under Linux?

example: i have 3 vlan (5,6,7) under linux and bridged already as 1 interface br0 cause i do not want to many entry on my iptables come to control the traffic from different VLAN. i works fine.

just when come to the query SNMP from the switch for monitoring purpose the big issue. cause all switch port give me same SNMP value.

How are you querying the switch? Some tools (ie RRDBrowse) will not work with some switches (ie Dell) switches (in this case, because RRDBrowse querys the MIB based on the string name of the interfance, and Dell switch ports all have an identical name...). Are you sure that when you query the individual switch ports you are generating unique queries?

i change my architecture already. i still use back each vlan one interface rather then bridge them up. i use SNMP to query the swtich, as long as i allow the SNMP from the switch (3com & Cisco) then no problem already.
