Policies

You can view the current global policy settings and configure the switch to use the policies you select.

Note: Before you type a command for port policies, select the desired port by typing po

#(where # is the desired port number).

An explanation of the available policies follows:

Policy	Description
Smart insertion	Ensures that data meets the requirements of Fibre Channel
	Arbitrated Loop (FC-AL) and allows sub-policies to be enabled.
Bad zone recovery	Reacts to bad zone indications by putting all ports through the
	normal insertion process and allowing only those ports sending
	ordered sets to insert.
No data recovery	The switch will automatically bypass a port if no K characters
	(Ordered Sets) are detected within a certain timeframe. The
	switch will try to reinsert the port upon detection of valid K
	characters.
LIP F8 recovery	Reacts to LIP(F8)s (indicating non-functional zones) by putting
	all ports through the normal insertion process and allowing only
	those ports not sending LIP(F8)s to insert.
LIP on port bypass	Requires bypassed ports to send LIP(F7)s to other zone
	members.
Auto cascade	When this policy is enabled, the switch will automatically
	configure itself and any other detected Vixel Inspeed devices in a
	cascade configuration.
	Note: This policy must be set to enabled if auto cascading on a
	port is enabled.
Bypass at max OS err	When this policy is enabled, the switch bypasses a port when
	that port exceeds the threshold of Ordered Set errors within a
	certain timeframe.
	(This policy applies to Zone 1 only.)
	The default timeframe is 10 seconds (see the Error Count
	Threshold setting).
Bypass at max CRC err	When this policy is enabled, the switch bypasses ports that
	exceed the set threshold of frame CRC errors. Compares the
	CRC transmitted with a frame to the CRC calculated in the
	switch.
	(This policy applies to Zone 1 only.)
Bypass on clock delta	When this policy is enabled, the switch compares the detected
err	line clock through the frame and the number of fill words
	inserted or deleted versus the switch’s internal clock. If the
	derived clock delta is too high, the port is bypassed.
Bypass on switch stall	When this policy is enabled and switching mode is on, the switch
	bypasses a stalled port if the connection is not terminated within
	a certain timeframe (see the Switch Stall Threshold setting).
Clear conn on sw stall	When this policy is enabled, the switch clears the port
	connection on a switch stall after a certain timeframe (see the
	Switch Stall Threshold setting).
