Referenceidentifies the field of the packet. Offset determines the number of bytes afterthe reference with which to begin the comparison. Size determines thenumber of bytes to compare to the string.Packet capture also supports one group parameter for each packet direction. Thegroup parameter allows you to specify whether the packet must match both filter 1and filter 2 in order for packet capture to copy it.Setting the Filter Response to a MatchTo set the response to a filter, enter the following commands:rx-filter-type for receive filter 1rx-filter2-type for receive filter 2tx-filter-type for transmit filter 1tx-filter2-type for transmit filter 2value is one of the following:• capture -- Copies only the packets containing the data that matches the string.• trigger -- Terminates when packet capture matches data in a packet with thestring. Packet capture will not copy the packet containing the match.• notused -- Copies every packet on a circuit, regardless of its contents. If youuse this setting, packet capture does not use the remaining parameter settingsfor the associated filter.Note: To avoid confusion, configure all parameter settings for one filter beforegoing to the next. For example, configure all receive filter 1 parameters beforeconfiguring the receive filter 2 parameters.Note: You can configure a filter with a type of capture or trigger, but not both.If you configure two receive filters, one a capture filter and the other a triggerfilter, make filter 2 the trigger filter.
