cDhcpv4ServerSharedNetFreeAddrHighThreshold
Module: CISCO-IETF-DHCP-SERVER-MIB
OID (symbolic): CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerSharedNetFreeAddrHighThreshold
OID (numeric): 1.3.6.1.4.1.9.10.102.1.4.1.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The high threshold for available free addresses in this shared network. If a cDhcpv4ServerFreeAddressLow event was generated for this subnet, and the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold, then a cDhcpv4ServerFreeAddressHigh event will be generated. No more cDhcpv4ServerFreeAddressHigh events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses becomes equal to or less than the value of cDhcpv4ServerSubnetFreeAddrLowThreshold.
What is cDhcpv4ServerSharedNetFreeAddrHighThreshold?
A configurable (read-write) high-watermark for the number of free IPv4 addresses in a DHCP shared network; once free addresses rise back above this value after a low-threshold event, the server generates a clear/recovery notification.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.4.1.1.3 snmpwalk -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerSharedNetFreeAddrHighThreshold
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.4.1.1.3.1 snmpget -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerSharedNetFreeAddrHighThreshold.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.10.102.1.4.1.1.3.1 i <value>
