ADMINISTRATION
The simple network management protocol (SNMP) is used by network management systems to monitor
network attached devices for conditions that warrant administrative attention. The SNMP V1/V2c/V3
are all supported by the switch. SNMP V1, and SNMP V2c use a community string match for
authentication, which means that SNMP servers access all objects with read-only or read/write
permissions using the community string public/private. SNMP V3 is based on V1.V2C, add USM (User-
based Security Model). Auth Protocol is the protocol used to create
the authentication key. It supports
MD5 or SHA. Priv Protocol is the protocol used to create encryption key. It supports DES or RSA. End
users can specify their own private key password.
It consists of a set of standards for network management, including an application layer protocol, a
database schema, and a set of data objects. SNMP exposes management data in the form of variables
on the managed systems, which describe the system configuration. These variables can then be queried
(and sometimes set) by managing applications. Over TCP/IP, SNMP usually uses UDP ports 161 (SNMP)
and 162 (SNMP-traps). SNMP agents reside in network devices where they use MIBs (information
specific to the device) to interface the devices with the NMS--which then monitors and controls devices
via these agents. An SNMP Trap is a message that is transmitted when a trap event occurs. A valid trap
receiver will receive a trap message when a trap event occurs.
MIBs are located under switch/lib/libsnmpmib.so
• RFC1213-MIB supported
• Cold-start TRAP supported.
