Command hdlcfilter

hdlcfilter <hdlc_filters_list>

This command sets the default HDLC filter used in the HDLC-to-UDP connections.

The field <hdlc_filters_list> can be no or comma- or whirespace-separated list of values: fisu, fisuall, lssu, lssuall, shortlssu, shortlssuall, longlssu, longlssuall, msu:

no: there is no any HDLC filter for the connection (all MTP SS7 messages will be sent to the remote host);

fisu: repeating FISUs will be filtered;

fisuall: all FISUs will be filtered;

lssu: repeating LSSUs will be filtered;

lssuall: all LSSUs will be filtered;

shortlssu: repeating short LSSUs will be filtered;

shortlssuall: all short LSSUs will be filtered;

longlssu: repeating long LSSUs will be filtered;

longlssuall: all long LSSUs will be filtered;

msu: all MSUs will be filtered.

Example:

  hdlcfilter fisuall lssuall

Note: to change default HDLC filter this command should be entered before creating any HDLC-to-UDP connection. If the default HDLC filter has not been changed, the setting

  hdlcfilter fisu lssu

is used (repeating FISUs and LSSUs are filtred).
