4.1 Configuring SNMP Settings via Console Operation
Before performing SNMP operation, proper SNMP settings must be configured. The SNMP related settings
are:
Name : Logic name to identify the switch unit
Location : Location where the switch unit is installed
Contact : Contact person regarding the switch unit
Community string : SNMP communities to which the SNMP manager belongs and access right to the
switch unit ( read only or read/write)
Trap Managers : IP addresses of trap managers to which a trap is
issued and the community to which the trap manager belongs.
Up to four SNMP communities and up to three trap managers are supported by the system SNMP agent.
4.2 SNMP MIB-2 and Private MIB
Use the SNMP management application software to compile the MIB file first before performing any management operation. The
following MIB standards are supported:
RFC1213 MIB-2
RFC1493 Bridge MIB
RFC1643 Ethernet-like MIB
RFC1271 RMON MIB statistics, history, alarm, event group
Private MIB (Device Specific)
The following MIB-2 objects are related to the switched ports and are indexed by a port number 1 ~ 27 (27
= CPU port):
Port MIB-2 Objects Set/Get Value Options
ifIndex.1 ~ 27 Get Physical port number
ifDescr.1 ~ 26 Get text - Port 1~26 on unit 1
