after a delay. If the master DHCP server is available, the DHCP relay agent forwards DHCP requests
to the master DHCP server. If the master DHCP server is not available, the DHCP relay agent still
uses the backup DHCP server.
To specify the DHCP server selecting algorithm in interface view:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the DHCP relay agent.
4. Specify a DHCP server
address.
5. Specify the DHCP server
selecting algorithm.
6. (Optional.) Set the DHCP
server response timeout time
for DHCP server switchover.
7. (Optional.) Enable the
switchback to the master
DHCP server and set the
delay time.
To specify the DHCP server selecting algorithm in DHCP address pool view:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the DHCP relay agent.
4. Return to system view.
5. Create a DHCP address pool
and enter its view.
6. Specify gateway addresses
for the clients matching the
DHCP address pool.
7. Specify DHCP servers for the
DHCP address pool.
8. Specify the DHCP server
selecting algorithm.

Remarks
N/A
N/A
By default, an interface operates in
the DHCP server mode when DHCP
is enabled.
By default, no DHCP server address
is specified.
By default, the polling algorithm is
used. The DHCP relay agent
forwards DHCP requests to all
DHCP servers.
By default, the DHCP server
response timeout time is 30
seconds.
By default, the DHCP relay agent
does not switch back to the master
DHCP server.
Remarks
N/A
N/A
By default, an interface operates in

is enabled.
N/A
By default, no DHCP address pool
exists.
By default, the DHCP address pool
does not have any gateway
addresses.
By default, the DHCP address pool
does not have any DHCP server IP
addresses.
You can specify a maximum of eight
DHCP servers for one DHCP
address pool for high availability.
By default, the polling algorithm is
used. The DHCP relay agent
forwards DHCP requests to all
DHCP servers.
