Summary


AUDIT FINDINGS – mpbnAll Circle - Routers

› Test nodeB – MPBN connectivity status checked & configuration to be updated

› Junk configuration like E1 configuration present in routers : to be deleted

› Additional static routes configured : to be acted upon after discussion with Idea team

› RSVP LSP Secondary path to be configured› Few ports not implemented as designed› Few VRF names to be changed as per convention› MTU on EoSDH – 4470 to be configured

All Circle - Switches

• Test nodeB – MPBN connectivity status checked & configuration to be updated.

• Few ports connecting to core nodes are highly utilized – capacity augmentation needed

• RSTP with ECI – dependency on ECI configuration• Few Ports wrongly configured in vlan’s & vice-versa• Few STP configuration and status need to be corrected• Load-sharing algorithm to be standardized

Microsoft Excel Worksheet


AUDIT FINDINGS – CS CORE› Signaling and Payload hardware configuration have been checked and no deviation found against BoQ.

› Uniformity found on current software release in all the MSS nodes.› IPMIGR parameter found enabled in many MSS and should be disabled.› MTU value for IP interface is set to 1436 in some MSS and M-MGWs. It should be changed to 1500.

› GCP profile 6 is used in MGW which is as per the recommendations.› SCTP buffer threshold is set to 128 and should be changed to 192.› SCTP buffer size is set to 128 is some MSS and MGW. It should be changed to 256.

› Incoming and Outgoing streams for all SCTP Association should be configured with value of 17.

› Routing path supervision is found active for signaling traffic in few M-MGW’s and should be disabled.



AUDIT FINDINGS – Ran›Rnc–No major deviation in RNC design vs implementation–Site distribution within RNC is uniform.–All RNCs are with W10B–Change In SPB board type

›Node-b–IP, VLAN design vs configuration are matching–Unique as well as shared VLANs in all major cities in all circles–Observed variations in Software levels. ›R4D (for DUW) and R6AD (for 6601E) Node B SW

Version


Audit findings – ML-TN›Deviations have been observed in nodes in some parameters settings with respect to the standard recommendations / design.

›20% Nodes are not visible from SO-EM due to POP readiness and DCN

›Most of the deviation findings are common for all the circles:

›Radio terminal configuration›LAN configuration›Traffic class configuration›Ethernet settings›Bandwidth profile›RSTP settings

›TN Software Version is different need to be upgraded to R4.4FP2 to solve the LAG issue.



AUDIT FINDINGS – h Ran›HRAN

–Configuration mismatches in ECI MUXes causing RSTP (broadcast/multicast) related problems between MPBN switches and ECI MUXes.

–Traffic prioritization in fiber network is in concurrence with L2 network requirement of 3G traffic

Summary


summary›End to End QoS implementation is required to be done at earliest

›Support Requested from Idea– Bandwidth requirement for all types of traffic needs to be provided for DSCP & QoS implementation

– RSTP configuration needs to be completed across ECI Muxes

– HRAN Bandwidth augmentation to be taken on war footing in MP & MH

›Implementation plan shared with Idea:– Non-traffic impacting implementation has already commenced

– Some of the implementations will require inputs from Idea

– Some implementations in TN can be taken up by Idea
