Changing the SCTP Checksum Algorithm Option for IPSG M3UA
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 M3UA associations that are assigned to all the IP cards running the IPSG application. This
option is a system-wide option. To apply this option to associations assigned to cards running the
IPLIM, IPLIMI, SS7IPGW, or IPGWI applications, or to IPSG M2PA associations, 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
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 F9 function key on the keyboard at the terminal where the rtrv-assoc command was
entered.
Enter the canc-cmd without the trm parameter at the terminal where the rtrv-assoc command
was entered.
Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-assoc command
was entered, from another terminal other that the terminal where the rtrv-assoc command was
entered. To enter the canc-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 the rtrv-secu-trm
command. The user's permissions can be verified with the rtrv-user or rtrv-secu-user
commands.
