Notes:
The MSC IP address, key part of the mapping definition, is used to identify a specific mapping definition.
isdn_number
: Enter a numeric string upto 15 digits long.
no msc-mapping ip-address
: Identifies a specific MSC IP address mapping definition to remove from the
MME Service configuration.
MME Service supports a maximum of 24 MSC mappings.
Use the

command to view configured mapping. The following is a sample of what the
MSC mapping information would look like:

CSCuu85922 - Problem with DNS query for APN with ‘gprs’ anywhere in APN
Name
Feature Changes
APN-FQDN String Construction
Previous Behavior: Earlier, the ".gprs" substring was replaced by ".3gppnetwork.org" present at any position of the
APN Network Identifier string, which is an undesired query function.
APN Network Identifier string, which is an undesired query function.
For example:
APN NI: "alwin.gprs.cisco.brussels"
DNS query output: alwin.apn.epc.mnc045.mcc456.3gppnetwork.org
New Behavior: Now, MME is modified to replace the ".gprs" substring if it is present only at the last label of the APN
Network Identifier. The ".gprs" is replaced by using the default APN-Operator Identifier (APN-OI) as per 3GPP TS
23.003. The APN-FQDN is obtained by inserting "apn.epc" label between the APN-NI and APN-OI and replacing
".gprs" with ".3gppnetwork.org" label.

For example:

DNS query output: cisco.com.apn.epc.mnc045.mcc456.3gppnetwork.org
Customer Impact: DNS query might fail if the existing APN-NI contains ".gprs" as a substring in any of the first two
labels.
