OID (symbolic): DECHUB900-COMMON-MIB-V3-0::pcomSnmpAuthReadOnlyUserMask

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.
What is pcomSnmpAuthReadOnlyUserMask?
A 32-bit wildcard mask applied to incoming source IP addresses to match against pcomSnmpAuthReadOnlyUserAddr, defaulting to all 1s (exact match). For example, an address of 16.20.0.0 with mask 255.255.0.0 lets any host on that /16 subnet poll the device read-only.
