Changing the SCTP Checksum Algorithm Option for M2PA Associations
Use this procedure to change the SCTP checksum algorithm, either Adler-32 or CRC-32c, applied to traffic on SCTP associations. The
sctpcsum parameter of the chg-sg-opts command is used to change this option. The Adler-32 and CRC-32c checksum algorithms specified in this procedure applies to all the associations that are assigned to all the IP cards running the IPLIM or IPLIMI applications. This option is a system-wide option. To apply this option to associations assigned to cards running the SS7IPGW, IPGWI, or IPSG applications, perform these procedures.
The sctpcsum parameter contains another value, percard, that allows either the Adler-32 or CRC-32c SCTP checksum algorithm to be specified for the all the associations assigned to a specific card. With this option specified, the Adler-32 checksum algorithm can be specified for the associations on one card and the CRC-32c checksum algorithm can be specified for the associations on another card. Setting the sctpcsum parameter to percard changes the SCTP checksum algorithm for the associations assigned to a card to the SCTP checksum algorithm value for that card. The checksum algorithm for individual cards is provisioned by performing the Configuring an IP Card procedure.
Once the SCTP checksum option has been changed, the associations on each IP card need to be reset by changing the open parameter value for each association to no, then back to yes. This ensures that the associations on the IP card are using the new SCTP checksum algorithm.
Canceling the RTRV-ASSOC Command
Because the rtrv-assoc command used in this procedure can output information for a long period of time, the rtrv-assoc command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-assoc command can be canceled.
- Press the
F9function key on the keyboard at the terminal where thertrv-assoccommand was entered. - Enter the
canc-cmdwithout thetrmparameter at the terminal where thertrv-assoccommand was entered. - Enter the
canc-cmd:trm=<xx>, where<xx>is the terminal where thertrv-assoccommand was entered, from another terminal other that the terminal where thertrv-assoccommand was entered. To enter thecanc-cmd:trm=<xx>command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with thertrv-secu-trmcommand. The user’s permissions can be verified with thertrv-userorrtrv-secu-usercommands.
For more information about the canc-cmd command, go to Commands User's Guide.

- Repeat 5 through 14 to update the other IP cards in the EAGLE running the IPLIM and IPLIMI applications with the new SCTP checksum algorithm.
- Back up the database by entering the
chg-db:action=backup:dest=fixedcommand. These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.BACKUP (FIXED) : MASP A - Backup starts on active MASP. BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete. BACKUP (FIXED) : MASP A - Backup starts on standby MASP. BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete. - If the
rtrv-cardoutput in 2 shows cards running the SS7IPGW or IPGWI applications, perform the Changing the SCTP Checksum Algorithm Option for M3UA and SUA Associations procedure.If thertrv-cardoutput in 2 shows cards running the IPSG application, perform these procedures.If the
rtrv-cardoutput in 2 shows that there are no cards running the SS7IPGW, IPGWI, or IPSG applications, this procedure is finished.
