SCTP debugging and troubleshooting

These enhancements include additional show command filter options, a new command for clearing associations, an additional trace flag option, and additional system log messages. Use the detail option of the show security gprs sctp counters command to view detailed debugging counters for SCTP packets. Use the show security gprs sctp association command to view established associations, and use additional options to filter the output. Use the clear security gprs sctp association command to clear SCTP associations. To configure debugging traces using the detail option, use the sctp traceoptions flag statement in the [edit security gprs] hierarchy. To configure the output of system log messages using the new association, data-message-drop, control-message-drop, control-message-all and rate-limit options, use the sctp log statement in the [edit security gprs] hierarchy.
