Usage guidelines
The DHCP server does not provide services during the binding download process. If the connection
disconnects during the process, the waiting timeout timer is 60 minutes. When the timer expires, the
DHCP server stops waiting and starts providing address allocation services.
To enable the DHCP server to provide services without waiting for the connection to be repaired, use
this command to terminate the download immediately. The IP addresses associated with the
undownloaded bindings will be assigned to clients. Address conflicts might occur.
Examples
# Terminate the download of the backup DHCP bindings.

Parameters
start-ip-address
: Specifies the start IP address.
end-ip-address
: Specifies the end IP address, which cannot be lower than the
start-ip-address
. If you do not specify this argument, only the
start-ip-address
is
excluded from dynamic allocation.
vpn-instance
vpn-instance-name
: Specifies an MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. If the excluded IP addresses belong to the public network,
do not specify this option.
Usage guidelines
The IP addresses of some devices such as the gateway and FTP server cannot be assigned to
clients. Use this command to exclude such addresses from dynamic allocation.
If the excluded IP address is in a static DHCP binding, the address can still be assigned to the client.
