What is lstIntPortNormallyCloseOpen?

This read-write enumeration (normally close/open) controls port traffic admission policy. Engineers set it to 'normallyOpen' to accept all traffic regardless of CAM content. 'normally Close' restricts traffic based on learned MAC addresses.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.19.4.1.1.1.18
snmpwalk -v2c -c public <target> APPLIC-MIB::lstIntPortNormallyCloseOpen

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.19.4.1.1.1.18.1
snmpget -v2c -c public <target> APPLIC-MIB::lstIntPortNormallyCloseOpen.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.19.4.1.1.1.18.1 i <value>
