Of course the switch is manageable via snmp.And the tutorial for net-snmp is covered too.
I have searched the result of "snmpwalk" to this switch, ending with some oids standing for the port numbers and the port macs.However, every oid is of fixed meaning.I just can't find the oid standing for the "enable/disable" function of my wanted port number, which is so hard to get.
