ctAgentDhcpServerExcludedAddressRangeCreate
Module: CT-FASTPATH-DHCPSERVER-MIB
OID (symbolic): CT-FASTPATH-DHCPSERVER-MIB::ctAgentDhcpServerExcludedAddressRangeCreate
OID (numeric): 1.3.6.1.4.1.52.4.2.32.1.2.4
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: It sets the IP address-ranges(from low to high) that a DHCP server should not assign to DHCP clients. Each time this MIB object is set successfully, one excluded range of IP address will be set. It is given in format - start and end IP address separated by '-' and terminated by ';'. One example would be - 192.168.36.1-200.1.1.1; . This sets one excluded range of IP address,which starts at 192.168.36.1 and ends at 200.1.1.1. If only start IP address is given, end IP address is assumed to be equal to the start IP address. Get operation on this MIB object returns a null-value, as for the purpose of viewing the exclude-address ranges, the user should perform the traversal of ctAgentDhcpServerExcludedAddressRangeTable. For this reason the get operation on object ctAgentDhcpServerExcludedAddressRangeCreate becomes insignificant.
What is ctAgentDhcpServerExcludedAddressRangeCreate?
This read-write DisplayString creates a new excluded address range, entered as start and end IP addresses separated by a hyphen and terminated by a semicolon, such as "192.168.36.1-200.1.1.1;", which the DHCP server will never assign to clients. An administrator uses this to protect statically assigned devices, like servers and network gear, from being accidentally offered by the dynamic pool. For example, an admin excluding the range used by fixed infrastructure would enter "192.168.10.1-192.168.10.20;" to keep those addresses out of dynamic assignment.
