/cfg/domain #/server/trace followed by:

tcpdump	Creates a dump of the TCP traffic flowing between
	clients and the virtual SSL server. You are prompted to
	enter the following information:
	•	tcpdump flags and tcpdump filter — for
		more information about the flags and filter
		expressions available for TCPDUMP using UNIX,
		see http://www.tcpdump.org/tcpdump_man.html.
	•	output mode
	Options for the output mode are:
	• interactive — captured information displays
		on the screen
	• tftpftpsftp — the dump will be saved as a
		file to the file exchange server you specify, using a
		destination file name you specify. You are prompted
		to enter the required information. You can specify
		the file exchange server using either the host name
		or the IP address.
		For TFTP, the number of files sent depends on the
		amount of captured information. A sequence
		number is appended to the file name given in the
		CLI, starting at 1 and incremented automatically for
		additional files.
		For ftp and sftp, you will also be prompted to
		specify a user name and password valid on the file
		exchange server.
	You can read a saved TCP traffic dump file using the
	TCPDUMP or Ethereal application on a remote
	machine.
	The default output mode is interactive.
ping <host>	Verifies station-to-station connectivity across the
	network.
	• host is the host name or IP address of the target
		station
	If a backend interface is mapped to the current Nortel
	SNAS 4050 domain, the check is made through the
	backend interface. To map a backend interface to the
	domain, use the
	/cfg/domain #/adv/interface command
	(see “Configuring advanced settings using the CLI” on
	page 145).
	To be able to use a host name, the DNS parameters
	must be configured (see “Configuring DNS servers and
	settings using the CLI” on page 477).
