I want to be able to send SNMP commands to up/down ports on my RV325 switch. However, when I try to use the standard OIDs (or an snmpwalk) it doesn't look like a normal 14 port switch, instead I seem to be seeing some internal architecture with 3 Ethernet ports (eth0, eth1, eth2, and other ports like gre0, sit0, ip6tnl0). What version SNMP should I use and what OID should I use to simply be able to up/down ports via SNMP set commands?
