Description (partial)

Symptom:
There are two issues noticed with the cli used to configured local-cause-code mapping for vlr-down and vlr-unreachable emm-cause code to imsi-unknown-in-hss.

1, Even though we have option to configure "local-cause-code-mapping vlr-down emm-cause-code imsi-unknown-in-hss" & "local-cause-code-mapping vlr-unreachable emm-cause-code imsi-unknown-in-hss" under mme-service.

When we issue "show config", in the above cli "hss" is replaced with "hlr"

    mme-service mmesvc
      s1-mme sctp port 25
      mme-id group-id 32777 mme-code 2
      plmn-id mcc 123 mnc 456
      associate egtp-service mme_egtp context MME
     .
     .
     .
     .
      local-cause-code-mapping congestion emm-cause-code eps-service-not-allowed-in-this-plmn esm-cause-code congestion
      local-cause-code-mapping vlr-down emm-cause-code imsi-unknown-in-hlr ======> this should be imsi-unknow-in-hss
      local-cause-code-mapping vlr-unreachable emm-cause-code imsi-unknown-in-hlr =====> this should be imsi-unknow-in-hss
      local-cause-code-mapping peer-node-unknown emm-cause-code network-failure.



2, After saving the config with "local-cause-code-mapping vlr-down emm-cause-code imsi-unknown-in-hlr" and "local-cause-code-mapping vlr-unreachable emm-cause-code imsi-unknown-in-hlr" configured under mme-service.
After we reload the MME[asr5k] with the saved config, the local-casue code with emm-cause-code imsi-unknow-in-hss is not getting configured again and the default cause code is configured againt vlr-down and vlr-unreachable.


NOTE:
The save and reload issue for local-cause-code-mapping.*" under mme-service is seen only when teh emm-cause-code is mapped to imsi-unknown-hss .

Conditions:
when the customer wants to use the ""local-cause code mapping cli configuration under mme-service for vlr-down/unreachable with mapped emm-cause code as "imsi-unknow-in hss"
