Supported SNMP MIBs
Netvisor ONE supports several MIBs which are run in a sub-agent to the SNMP daemon (master). Netvisor ONE uses the AgentX protocol for communicating between the SNMP daemon and the sub-agent.
When you issue an snmp-show command, the SNMP daemon receives the SNMP walk request and transfers the call to a sub-agent based on the SNMP OID of the request. The sub-agent populates the SNMP container to Netvisor ONE and displays the data. Netvisor ONE supports the following MIBs:
- IfTable (IF-MIB)
- IfXTable (IF-MIB)
- EntPhySensorTable (ENTITY-SENSOR-MIB)
- BGP MIB. The following BGPv4 tables are supported:
- bgpPeerTable
- bgp4PathAttrTable
- OSPF MIB. The following OSPF tables are supported:
- ospfGeneralGroupTable
- ospfAreaTable
- ospfLsdbTable
- ospfIfTable
- ospfExtLsdbTable
- ospfNbrTable
- ospfIfMetricTable
- OSPFv3 MIB Tables. The following OSPFv3 tables are supported:
- ospfrv3GenealGroupTable
- ospfv3AreaTable
- ospfv3NbrTable
- ospfv3IfTable
- ospfv3AreaLsdbTable
- ospfv3AsLsdbTable
- ospfv3LinkLsdbTable
- IEEE8021-Q-BRIDGE-MIB (ieee8021QBridgePortVlanStatisticsTable)
- IEEE8021-Q-BRIDGE-MIB (ieee8021QBridgeVlanStaticTable)
- IEEE8021-SPANNING-TREE-MIB (ieee8021SpanningTreePortTable)
- IEEE8021-SPANNING-TREE-MIB (ieee8021SpanningTreeTable)
- IP-MIB (ipv4InterfaceTable, ipv6InterfaceTable)
- DISMAN-EVENT-MIB
- UCD-SNMP-MIB
- Pluribus Enterprise PN-VRRP-MIB (supports IPv6 VRRP state change)
- Pluribus Enterprise PN-HR-MIB (pnHrCPUTable, pnHRMemTable)
- Pluribus Enterprise PN-FABRIC-MIB (pnFabricTable)
- Pluribus Enterprise PN-COS-MIB (pnCosStatsTable, pnCosBezelStatsTable)
- Pluribus Enterprise PN-LOG-MIB (pnLogMatchName, pnLogFileName, pnLogMatchData, pnLogMatchCount)
Note: Pluribus Enterprise PN-LOG-MIB is used for the generation of message-based traps only.
Netvisor ONE version 6.0.0 adds a new OID (pnVrrpPreemptMode.0) to the Pluribus proprietary PN-VRRP-MIB, which is mapped to the standard VRRP-MIB v3. The value of this OID is 'true(1)' when VRRP preempt mode is enabled (default status) and 'false(2)' when VRRP preempt mode is disabled.
The above MIBs consolidate into a single sub-agent, called nvOS_snmpd agent, which communicates with the master SNMP daemon and serves requests to the MIBs. All the MIBs except the routing MIBs are part of the nvOS_snmpd agent.
