Table 17 describes the parameters and variables for the config atm <ports> command.

Table 17 config atm command parameters and variables

Parameters and variables	Description
action <action choice>	Flushes a MAC, ARP, or IP table or triggers a RIP update. Choices are:
	•	none
	•	flushMacFdb
	•	flushArp
	•	flushIp
	•	flushAll
	•	triggerRipUpdate
number-vpi-bits <number-vpi-bits>	•	Sets the number of bits used to represent VPI. Enter integer from 0
		to 8.
	• For OC-3c, 11 bits split between NumVpiBits and NumVciBits.
		NumVpiBits cannot exceed 6 bits for OC-3c.
	• For OC-12c, 13 bits split between NumVpiBits (default is 4) and
		NumVciBits (default is 9). NumVpiBits cannot exceed 8 bits for
		OC-12c.
scrambling <enable disable>	Enables or disables scrambling.
framing-mode <sonet sdh>	Sets the framing to:
	• sonet (Synchronous Optical Network), the standard format used in
		North America.
	• sdh ( Synchronous Digital Hierarchy), the standard format used
		worldwide except in North America.
clock-source <loop-timed	Sets the transmit clock source to:
free-running>	• loop-timed, which means clocking is derived from line.
	• free-running, which means clocking is derived from on-board clock.
	Note that if you have two connected Passport 8672ATME Modules,
	you must set both to free-running or one to loop-timed and one to
	free-running; do not set both to loop-timed.
loop-back-mode <off internal	Sets the loopback mode to:
remote>	•	off
	•	internal
	•	external
