To avoid IP address conflicts, the DHCP server checks whether an IP address is in use before assigning
it to a DHCP client.
The DHCP server pings the IP address to be assigned by using ICMP. If the server gets a response within
the specified interval, the server selects and pings another IP address. If not, the server pings the IP
address again until the specified number of ping attempts is reached. If still no response is received, the
server assigns the IP address to the requesting client.
Examples
# Specify the response timeout time as 1000 ms.
<Sysname> system-view
[Sysname] dhcp server ping timeout 1000
dhcp server relay information enable
Syntax
dhcp server relay information enable
undo dhcp server relay information enable
View
System view
Default level
2: System level
Parameters
None
Description
Use the dhcp server relay information enable command to enable the DHCP server to handle Option 82.
Use the undo dhcp server relay information enable command to configure the DHCP server to ignore
Option 82.
By default, the DHCP server handles Option 82.
Examples
# Configure the DHCP server to ignore Option 82.
<Sysname> system-view
[Sysname] undo dhcp server relay information enable
display dhcp server conflict
Syntax
display dhcp server conflict { all | ip ip-address }
View
Any view
Default level
1: Monitor level
