cpqnAclIPAddrMask
Module: CPQNUNIF-MIB
OID (symbolic): CPQNUNIF-MIB::cpqnAclIPAddrMask
OID (numeric): 1.3.6.1.4.1.232.121.4.2.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: DURABLE: This mask is applied to the source address of received SNMP/IP messages. If the masked address matches cpqnAclIPAddrMatch and the community in the SNMP packet matches the community name in cpqnAclIPCommunity for the row, then the SNMP request will be serviced by the unit's agent. The transmitting node's access to this unit's MIB tables is determined by the cpqnAclIPRights. For example, assuming cpqnAclIPAddrMask = 255.255.255.000, cpqnAclIPAddrMatch = 198.085.034.000, and cpqnAclCommunity = compaq, then a SNMP request coming from 198.85.34.72 with community compaq will pass whereas a request from 120.1.2.4 with community compaq will fail.
What is cpqnAclIPAddrMask?
This read-write IP address value is the subnet mask applied to the source address of incoming SNMP/IP requests before comparing it against cpqnAclIPAddrMatch to decide whether to service the request. An admin sets this to control how broad or narrow an IP-based access rule is, e.g. masking down to a specific host or allowing an entire subnet. For example, setting cpqnAclIPAddrMask to 255.255.255.000 would let the associated rule match any host within a /24 subnet rather than a single IP.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.121.4.2.1.3 snmpwalk -v2c -c public <target> CPQNUNIF-MIB::cpqnAclIPAddrMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.121.4.2.1.3.1 snmpget -v2c -c public <target> CPQNUNIF-MIB::cpqnAclIPAddrMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.232.121.4.2.1.3.1 a <value>
