NAME
snmp-mibII.schema - SNMP MIB-II schema.
DESCRIPTION
snmp-mibII.schema contains data definitions for MIB-II objects defined in RFC 1213. The SNMP proxy agent can use this schema to return information from SNMP agents that use the MIB-II data definitions.
The attribute definitions for this schema are shown below.
ATTRIBUTES
snmp-mibII.schema contains 16 attribute groups (system, interfaces, ipStatus, ipInput, ipOutput, icmpInput, icmpOut-put, tcp, udp, egp, transmission, snmpStatus, snmpInput, snmpInputErrors, snmpOutput, snmpOutputErrors) and ten attribute tables (ifStatus, ifInput, ifOutput, atTable, ipAddrTable, ipRoutingTable, ipNetToMediaTable, tcpConnT-able, udpTable, egpNeighTable).
