Enter an integer from 60 to 600. Default is 300.
Usage
Setting this timer to a valid value enables the Local DNS feature - described in the SGSN Administration
Guide. Setting this timer marks a GGSN in the primary GGSN pool as unavailable for PDP context creation
and causes the SGSN to forward a PDP Context Activation Request to a remote pool GGSN, identified via a
local (on the SGSN) DNS check. Marking a GGSN unavailable can be done if there is a reason to believe the
GGSN is unavailable; for example, lack of response to GTP messages. Marking a GGSN as unavailable is
usually done for a limited period to allow the GGSN time to recover.
