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?

snmp query

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.
