R0106-HP MSR Router Series Layer 3 - IP Services Command Reference(V7)

56
• Add options for which the CLI does not provide a dedicated configuration command. For example,
you can use the option 4 ip-address 1.1.1.1 command to define the time server address 1.1.1.1 fo r
DHCP clients.
• Add all option values if the actual requirement exceeds the limit for a dedicated option
configuration command. For example, the dns-list command can specify up to eight DNS servers.
To specify more than eight DNS server, you must use the option 6 command to define all DNS
servers.
If a DHCP option is specified by both the dedicated command and the option command, the DHCP
server assigns the content specified by the dedicated command. For example, if a DNS server address
is specified by the dns-list command and the option 6 command, the server uses the address specified
by dns-list command.

Parameters
ip ip-address: Clears conflict information about the specified IP address. If you do not specify this option,
this command clears all address conflict information.
Usage guidelines
Address conflicts occur when dynamically assigned IP addresses have been statically configured for
other hosts. After you modify the address pool configuration, the conflicted addresses might become
assignable. To assign these addresses, use the reset dhcp server conflict command to clear the conflict
information first.
Examples
# Clear all IP address conflict information.
<Sysname> reset dhcp server conflict
