The S-GW will generate peg counts of the total number of received GTP-C messages containing an Allocation and Retention Priority (ARP), chosen from the set of values allocated for NS/EP NGN-PS use, for a specified interval (in minutes). This peg count is administered at the S-GW level.
The P-GW will generate peg counts of the total number of received GTP-C messages containing an ARP, chosen from the set of values allocated for NS/EP NGN-PS use, for a specified interval (in minutes). This peg count is administered at the specific P-GW level.
The peg counts for GTP-C messages are broken down by message type similar to existing GTP-C message counters. The bulkstats are broken down by applicable S-GW and P-GW service and S5, S8, S11, and S4 interfaces.
Bulkstats are added for eMPS session/message.
For piggy-back messages, if either of the messages have matching ARP or result into converting non-eMPS session to eMPS session, then both messages are counted as eMPS message and corresponding statistics for both messages are incremented.
If Modify Bearer Request is piggy-backed with Create Bearer Response on S11 interface of S-GW and Create Bearer Response result into converting non-eMPS session into eMPS session, then Modify Bearer Response statistics will not increment for this Modify Bearer Request.
Bulkstats Collection and Reset
Bulkstats are added under eGTP-C Schema and pgw-egtpc-s5s8 Schema. These eMPS bulkstats in eGTP-C Schema and pgw-egtpc-s5s8 Schema holds value only for a bulkstat interval, that is, value of these bulkstats shows number of eMPS messages exchanged during the bulkstat interval.
Peer level and APN level statistics are not collected.
MPS statistics recovery is not supported.
MPS statistics are not collected for CSReq, DDNReq, and change notification messages rejected by demux with ARP for eMPS sessions.
MPS statistics are not collected for retried/re-transmitted messages.
Bulkstats for GTP-C Messages by ARP Value feature requires that a valid license key be installed. Contact your Cisco Account or Support representative for information on how to obtain a license.
