setSplbMode

Enable or disable 2 port loop-back.
Synopsis
setSplbMode [0|1]
Availability
admin
Description
Use this command to enable or disable SPLB mode. The mode is saved in flash memory and stays
in that mode until the next execution of setSplbMode. The mode becomes active as soon as this
command is executed. It does not require a reboot to take effect.
The SPLB mode, when enabled, forces the spinSilk command to disable two port loopback for
M->M connected ports. This may be useful to isolate internal switch problems from GBIC problems
since the internal paths are used much less with SPLB mode enabled.
The SPLB mode, when disabled, forces the spinSilk command to circulate frames between pairs of
M->M connected ports as follows:
P1 TX >>> P1 RX -> P2 TX >>> P2 RX -> P1 TX
where:
>>> is a cable or internal loop-back
-> is a routing table entry
The connections between pairs of M->M ports will be chosen to exercise the connections between
as many chips (or bloom quadrants) as possible subject to the setting of allow_intra_chip and the
availability of pairs of M->M ports.
Any ports that are cross-cabled will be routed to each other in the normal manner regardless of the
setting of SPLB mode:
P1 TX >>> P2 RX -> P1 TX
P2 TX >>> P1 RX -> P2 TX
