What is snVLanByIpSubnetChassisDynamicMask?

Reports the 32-byte bitmask of chassis ports currently active in a subnet-based VLAN based on observed IP subnet traffic. An admin reads this to see the VLAN's live port membership as learned dynamically, versus the static configuration.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.3.7.11.12.1.3.2.3.1.12
snmpwalk -v2c -c public <target> HP-SN-SWITCH-GROUP-MIB::snVLanByIpSubnetChassisDynamicMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.3.7.11.12.1.3.2.3.1.12.1
snmpget -v2c -c public <target> HP-SN-SWITCH-GROUP-MIB::snVLanByIpSubnetChassisDynamicMask.1
