Traffic marked with a higher class is given priority during congestion periods. If congestion occurs to traffic
with the same class, the packets with the higher AF value are dropped first.
with the same class, the packets with the higher AF value are dropped first.
max-retransmissions num
Configures the maximum number of retries for packets as an integer from 0 through 15. Default: 4
After max retransmissions is reached, the path is considered to be failed.
After max retransmissions is reached, the path is considered to be failed.
node-feature pgw-restart-notification
Enables P-GW Restart Notification functionality. Node will start announcement of new supported features to
peer nodes in echo as soon as configuration is added.
From release 17.0 onwards the S4-SGSN and MME support receiving/advertising the P-GW Restart
Notification (PRN). This command option must be configured in order to inform S-GW that S4-SGSN and/or
MME supports receiving/advertising the PRN in EGTPC echo request/response messages.
Default: Disabled

node-feature network-triggered-service-restoration
This keyword applies to the MME and S-GW only.
Enables Network Triggered Service Restoration (NTSR) functionality as per 3GPP TS 23.007 Release 11 for
this EGTP service.
Upon receipt of a Downlink Data Notification (DDN) message including an IMSI, the MME will accept the
request and initiate paging including the IMSI in order to force the UE to re-attach. IMSI-based DDN
requests contain a zero TEID. Since the UE is not attached, the UE will be paged over the whole MME
coverage area.
A different MME may be selected by the eNodeB to service the attach request. Since the MME that serviced
the DDN will not be aware that the UE has responded with the attach request, it will stop paging upon a
timeout.
