The default virtual channel settings have already been optimized for switch performance. Changing
the default values can improve switch performance but can also degrade performance. Do not
change these settings without fully understanding the effects of the changes.
lists the virtual channel settings.
VC Priority specifies the class of frame traffic given priority for a virtual channel.
F_Port Login Parameters
Specifies the F_Port login parameters.
Maximum logins per switch
Sets a switch-wide limit on allowed logins. The maximum login per switch has
decreased with Fabric OS v6.4.0. When upgrading from pre-v6.4.0 firmware
versions, the configured maximum is carried forward and may exceed the
v6.4.0 limit. It is recommended to reconfigure this parameter to be within the
range permitted in Fabric OS v6.4.0.
The following three parameters are related to staged F_Port logins by FLOGI requests and virtual
device logins by FDISC(SID==0) requests.
Logins per second Specifies the number of logins the switch accepts per second in staged
F_Port bring up.
Login stage interval Specifies the stage interval in staged F_Port bring up.
Stage FDISC logins This parameter, if nonzero, enables staging of FDISC logins by rejecting the
FDISC requests with "logical busy", when the requests are more than the
number of configured "logins per second". It also specifies the number of
FDISC requests that will always be accepted first without reject.
Unless there are issues with F_Port staging, do not change default values.
