Note : The following process is done automatically by the MTA. The NCS is not involved in creating signaled entries . The current CMS signaling association being used by an endpoint is marked as active in CMS MAP table. If NCS signaling requests a change of signaling association to a di fferent FQDN， the MTA checks the current CMS MAP table entries for the affected endpoint. If the entry exists in the CMS MAP table， the current CMS MAP table entry is marked inactive and the newly chosen CMS MAP table entry is marked active. If the entry does not exist in the CMS MAP table, the CMS table is checked to determine whether or not it contains the CMS specified by CMS signaling (possibly a redi rection) . If the desired CMS entry is defined, then a corresponding entry is created and an entry in the CMS MAP table is created. If the MTA does not have current associations with that CMS， it will now perform key management to establish required security associations. Once the desired CMS entry is establ i shed, the current CMS MAP table entry is marked inactive and the newly created CMS MAP table entry is marked act ive . Otherwise the current CMS MAP table entry remains . active and the newly created CMS MAP table entry is marked in active .
If the entry does not exist in the CMS MAP table and the . CMS entry does not exist in the CMS table, a new CMS table entry should be created. This CMS entry should use the same realm as used by this endpoint. The default values for the clock skew and AP request/AP reply adaptive backoff parameters should be used. The MTA will now perform key management to establish required security associations. Once the desired CMS entry is establ i shed, the current CMS MAP table entry is marked inactive and the newly created CMS MAP table entry is marked act ive . Otherwise the current CMS MAP table entry remains active and the newly created CMS MAP table entry is marked inactive. When the MTA receives wake-up or rekey messages from a CMS, it performs key management based on the corresponding entry in the CMS table. If the matching CMS entry does not exist, it must ignore the wake-up or rekey messages.
pkt cMt aCmsMapCmsIndex – the index of the CMS entry in the pkt cMt aDevCmsTable. Valid indices are equal to current pkt cMt aDevCmsIndex values. pkt cMt aCmsMapOperStatus – this value indicates which signaling association the endpoint is actively using pkt cMt aCmsMapAdminStatus – this flag indicates whether or not an endpoint should use a particular CMS and its security association. By setting this flag to inhibit, this associated CMS cannot provide signaling to the referenced endpoint. pkt cMt aCmsMapRowStatus – allows for the creation and deletion of endpoint mappings via the NMS
