SNMP Agent
Simple Network Management Protocol (SNMP) is the defacto standard for network management.
An SNMP agent maintains a structure of data for a network device in a virtual information
database, called a Management Information Base (MIB). A network management station is
capable of accessing the MIB of the network device to monitor and configure the network device.

The OpenArchitect switch utilizes the NET-SNMP (formerly UCD-SNMP) agent core.

OpenArchitect switch agent will respond to SNMPv1, SNMPv2, and SNMPv3 requests.
Protocols supported on the OpenArchitect switch by gated, such as RIP and OSPF communicate
with SNMP agent via the SNMP Multiplexing (SMUX) protocol.

Supported MIBS
OpenArchitect includes MIB support as documented by each of the RFCs listed. The MIBs
themselves are located on the switch in the /usr/share/snmp/mibs directory.
