▄ Release Change Reference, StarOS Release 17
306
Previous Behavior: The maximum number of retransmissions for Echo Requests was configured by
max-
retransmissions
configuration option.
New Behavior:
echo-max-retransmissions
is introduced explicitly for the configuration of echo max
retransmissions in both GTPC Service Configuration Mode.
Command Changes
gtpc echo-max-retransmissions
The
echo-max-retransmissions
keyword is now available in EGTP Service Configuration Mode. This keyword is
available to allow for the separate configuration of GTP echo retransmissions.
configure
context context_name
egtp-service egtp_service_name
gtpc echo-max-retransmissions number
default gtpc echo-max-retransmissions
end
Notes:
Important:
service_name
must be unique across all contexts.
echo-max-retransmissions
: Configures the maximum retries for GTP Echo requests. This option must be
an integer from 0 to 15. The default is 4. If
echo-max-retransmissions
configuration option is not
configured, then the
max-retransmissions
configuration will be used for maximum number of echo retries.
Performance Indicator Changes
show egtp-service [ all | name
service_name
]
The output of this command has been enhanced to show the configured number of GTPC echo max retransmissions.

CSCum35622 - Ability to define same TAI in multiple TAI Lists
Feature Changes
Ability to define same TAI in multiple TAI Lists
Prior to 17.0, the MME could have a tracking area in only one tracking area list (TAI List). Consequently, the tracking
area list assigned to subscribers attaching from different TAIs will be same, even if the adjacency of these tracking areas
is not same. This results in MME getting TAUs even as subscribers moved to the adjacent area.
