Value
Description
LoopTestOn 0 Cable loop test enable.
When SM starts, if LoopTestOn is set to 1 a loop
test will be started in normal mode. The LoopTest-
Packets setting will specify how many packets will
be injected into the loop test when started.
LoopTest is a good way to validate ISL's between
switches in a cluster.
By default Loop test runs in default mode. In the
default mode, the SM uses an exhaustive
approach to setup loop routes and will include
each ISL in as many loops as possible. This
ensures that each ISL is exactly in the same number
of loops and hence will see the same amount
of utilization. But finding all possible loops is computationally
intensive and can take a long amount
of time.
LoopTestFastMode 0 Puts LoopTest in fast mode when set to 1, when
started based on LoopTestOn setting.
Under this mode, loop test doesn't attempt to
include each ISL in all possible loops, but includes
it in at least the specified number of loops (this
value is controlled via the MinISLRedundancy
parameter).
In typical fast mode operations (with the default
MinISLRedundancy of 4), injecting four packets
into each loop is sufficient to get a high utilization
on the ISLs.
LoopTestPackets 0 Number of packets to inject. If the XML tag is not
set or commented out in the XML configuration file
but loop test has been enabled in the configuration
file, then a loop test will start but since the packet
count is zero, no packets will be injected into the
loops for testing. Using one of the inject CLI commands
the user can manually inject packets.
LIDSpacing 0 Spacing of LIDs to test LFT
SaRmppChecksum 0 RMPP internal checksum
DynamicPortAlloc 1 This parameter is for development use only.
