clients serviced by the specified group of interfaces before reconfiguration is considered
to have failed. A group configuration takes precedence over a DHCP local server
configuration.
Options attempt-count—Maximum number of attempts.
Range: 1 through 10
Default: 8
Required Privilege
Level
system—To view this statement in the configuration.
