chasEntitySrcSubnetMask
Module: DECHUB900-CHASSIS-MIB-V3-0
OID (symbolic): DECHUB900-CHASSIS-MIB-V3-0::chasEntitySrcSubnetMask
OID (numeric): 1.3.6.1.4.1.36.2.18.11.1.1.1.2.2.1.16
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: This object is used in conjunction with the chasEntitySrcIpAddress to provide HOST IP ADDRESS AUTHENTICATION. Refer to chasEntitySrcIpAddress for a description
For an entity that does not support the subnet mask, this value is 0.0.0.0.
What is chasEntitySrcSubnetMask?
The subnet mask used together with chasEntitySrcIpAddress to authenticate management traffic by matching a whole subnet instead of a single host; 0.0.0.0 if the entity doesn't support subnet-based authentication. An admin would see something like FF.FF.0.0 here to authorize an entire /16 management subnet rather than one address.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.1.1.1.2.2.1.16 snmpwalk -v2c -c public <target> DECHUB900-CHASSIS-MIB-V3-0::chasEntitySrcSubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.1.1.1.2.2.1.16.1 snmpget -v2c -c public <target> DECHUB900-CHASSIS-MIB-V3-0::chasEntitySrcSubnetMask.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> chasEntitySrcSubnetMask.1
