> IPSP Configuration Mode Commands
> The IPSP Configuration Mode is used to configure properties for the IP Pool Sharing Protocol (IPSP). System-based HA services use IPSP during an offline-software upgrade to avoid the assignment of duplicate IP addresses to sessions while allowing them to maintain the same address, and to preserve network capacity
> Important: For information on configuring and using IPSP refer to the System Administration and Configuration Guide.
> dead-interval
> Configures the retry time to connect to the remote system for the IP Pool Sharing Protocol.
> Product
> PDSN, HA
> Privilege
> Security Administrator, Administrator
> Syntax
> dead-interval seconds
> [ no | default ] dead-interval
> no
> Disables the dead interval. On loss of connectivity to the remote system, no retries are attempted and the remote system is marked dead immediately on failure.
> default
> Resets the dead interval to the default of 3600 seconds.
> seconds
> Default: 3600 seconds
> The amount of time in seconds to wait before retrying the remote system. seconds must be an integer from 25 through 259200.
> Usage
> Use this command to set the amount of time to wait before retrying to connect with the remote system for the IP pool sharing protocol.
> Example
> Use the following command to set the interval to 180 seconds (3 minutes):
> dead-interval 180
> end
> Exits the current configuration mode and returns to the Exec mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Use this command to return to the Exec mode.
> exit
> Exits the current mode and returns to the parent configuration mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Use this command to return to the parent configuration mode.
> reserved-free-percentage
> This command is used to set the amount of free addresses reserved for use on the primary HA.
> Product
> PDSN, HA
> Privilege
> Security Administrator, Administrator
> Syntax
> reserved-free-percentage value
> default reserved-free-percentage
> value
> Default: 100
> value specifies the percentage of free addresses reserved for the use on the primary HA for IP pool sharing during upgrade. It must be an integer from 0 through 100.
> Usage
> This command is used with pool-sharing-protocol active mode on the primary HA. Before using this command, pool-sharing-protocol in the Ethernet Interface Configuration Mode must be configured.
> For more information, refer to the Ethernet Interface Configuration Mode Commands chapter in this guide.
> Example
> To reserve 40 percent of free addresses in primary HA for IP pool sharing, enter the following command:
> reserved-free-percentage 40
