Description: Subnet mask associated with the Subnet IP address.
What is snVLanByIpSubnetSubnetMask?
This object provides the subnet mask associated with an IP subnet used to define VLAN membership based on IP address ranges. Combined with the subnet IP address, it defines which hosts belong to a particular VLAN without requiring MAC address configuration. Network administrators use this for dynamic VLAN assignment where users obtain IP addresses and are automatically placed in the corresponding VLAN.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.2.3.1.3 snmpwalk -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snVLanByIpSubnetSubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.2.3.1.3.1 snmpget -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snVLanByIpSubnetSubnetMask.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> snVLanByIpSubnetSubnetMask.1
