Policies
Note: The mc command
must be entered prior to
issuing one of the submenu
commands.
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
err
When this policy is enabled, the switch compares the detected
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).
