Entering the above command sequence results in the following prompt:
[context_name]host_name(config-dhcp-service)#
Syntax
dhcp server selection-algorithm { first-server | round-robin | use-all }
first-server
Uses the first-server algorithm. This algorithm dictates that the system select the DHCP servers according to
their priority starting with the highest priority server. The system communicates with the server of the next
highest priority only when the previous server is unreachable. Default: Enabled
their priority starting with the highest priority server. The system communicates with the server of the next
highest priority only when the previous server is unreachable. Default: Enabled
round-robin
Uses the round-robin algorithm. This algorithm dictates that the system communicates with the servers in a
circular queue according to the server’s configured priority starting with the highest priority server. The next
request is communicated with the next highest priority server, and so on until all of the servers have been
used. At this point, the system starts from the highest priority server. Default: Disabled
circular queue according to the server’s configured priority starting with the highest priority server. The next
request is communicated with the next highest priority server, and so on until all of the servers have been
used. At this point, the system starts from the highest priority server. Default: Disabled
use-all
Default: Disabled
This algorithm dictates that the system to communicate with the all the DHCP servers configured on system.
This algorithm dictates that the system to communicate with the all the DHCP servers configured on system.
Usage
Use this command to determine how configured DHCP servers are utilized by the system.
Example
The following command configures the DHCP service to use the round-robin selection algorithm:
