Module: DECHUB900-COMMON-MIB-V3-0
OID (symbolic): DECHUB900-COMMON-MIB-V3-0::pcomSnmpAuthReadWriteUserMask
OID (numeric): 1.3.6.1.4.1.36.2.18.11.2.5.3.2.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: UserMask is used to provide 'wildcard' authorized users.
It is a 32-bit mask which is applied to (ANDed with) the source IP address of an incoming SNMP message. If the result of the mask is equal to an address in pcomSnmpAuthReadOnlyUserAddr, the message is considered to have come from a user who has Read-only access. This allows wildcarding. For example, a user address of 16.20.0.0 and a mask of 255.255.0.0 allow access to all NMS's on subnet 16.20. The default value for this mask is all 1's.
Note, this object may only be read or written using the read-write community. Read-only access to this object is denied.
What is pcomSnmpAuthReadWriteUserMask?
A wildcard mask applied to the source address of incoming SNMP requests to match against a read-write user's address, defaulting to all 1s; also only accessible via the read-write community. Combined with a subnet-style mask and address, it lets an admin authorize an entire management subnet for write access rather than a single host.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.2.5.3.2.1.2 snmpwalk -v2c -c public <target> DECHUB900-COMMON-MIB-V3-0::pcomSnmpAuthReadWriteUserMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.2.5.3.2.1.2.1 snmpget -v2c -c public <target> DECHUB900-COMMON-MIB-V3-0::pcomSnmpAuthReadWriteUserMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.11.2.5.3.2.1.2.1 s <value>
