What is noAddFree?
This counter reports the number of IP addresses within a given DHCP scope that remain available for the server to lease out. Admins watch it to know how much headroom remains before a subnet runs out of addresses to assign. For example, a rapidly shrinking value here would prompt an admin to consider expanding that subnet's address range.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.311.1.3.2.1.1.3 snmpwalk -v2c -c public <target> DHCP-MIB::noAddFree
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.311.1.3.2.1.1.3.1 snmpget -v2c -c public <target> DHCP-MIB::noAddFree.1
