Resets the system to the default number of consecutive failures.

max_number
Default: 5
Specifies the number of failures that could occur before marking a CGF as down as an integer from 0 through
1000. If 0 (zero) is the value entered, the system will mark the CGF as dead after a single instance of max-
retries has been attempted with no success, regardless of configured deadtime.

Usage
This command works in conjunction with the gtpp max-retries parameter to set a limit to the number of
communication failures that can occur with a configured CGF.
The gtpp max-retries parameter limits the number of attempts to communicate with a CGF. Once that limit
is reached, the system treats it as a single failure. The gtpp detect-dead-server parameter limits the number
of consecutive failures that can occur before the system marks the CGF as down and communicate with the
CGF of next highest priority.
If all of the configured CGFs are down, the system ignores the detect-dead-server configuration and attempt
to communicate with highest priority CGF again.
If the system receives a GTPP Node Alive Request, Echo Request, or Echo Response message from a CGF
that was previously marked as down, the system immediately treats it as being active.
