snmpTargetAddrTMask

Module: SNMP-COMMUNITY-MIB

OID (symbolic): SNMP-COMMUNITY-MIB::snmpTargetAddrTMask

OID (numeric): 1.3.6.1.6.3.18.1.2.1.1

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-create

Description: The mask value associated with an entry in the snmpTargetAddrTable. The value of this object must have the same length as the corresponding instance of snmpTargetAddrTAddress, or must have length 0. An attempt to set it to any other value will result in an inconsistentValue error.

The value of this object allows an entry in the snmpTargetAddrTable to specify multiple addresses. The mask value is used to select which bits of a transport address must match bits of the corresponding instance of snmpTargetAddrTAddress, in order for the

transport address to match a particular entry in the snmpTargetAddrTable. Bits which are 1 in the mask value indicate bits in the transport address which must match bits in the snmpTargetAddrTAddress value. Bits which are 0 in the mask indicate bits in the transport address which need not match. If the length of the mask is 0, the mask should be treated as if all its bits were 1 and its length were equal to the length of the corresponding value of snmpTargetAddrTable.

This object may not be modified while the value of the corresponding instance of snmpTargetAddrRowStatus is active(1). An attempt to set this object in this case will result in an inconsistentValue error.

What is snmpTargetAddrTMask?

This object is a bitmask paired with a target address entry, used to match ranges of transport addresses against a single snmpTargetAddrTable row instead of one address per entry. Bits set to 1 in the mask must match the corresponding bits of the address exactly, while bits set to 0 are wildcards, letting one entry cover an entire subnet of trap receivers or authorized managers. For example, a mask matching a /24 IPv4 subnet lets any host in that subnet be treated as matching the entry, rather than requiring a separate row per host.
