To configure an Fabric Shortest Path First (FSPF) feature for an entire Virtual SAN (VSAN), use the fspf config command. To delete an FSPF configuration for the entire VSAN, use the no form of this command.

vsan
vsan-id
|
Specifies a VSAN ID. The range is from 1 to 4093.
|
|
min-ls-arrival
ls-arrival-time
|
Specifies the minimum time before a new link state update for a domain will be accepted by the switch.
ls-arrival-time
is an integer that specifies time in milliseconds. The range is from 0 to 65535.
|
|
min-ls-interval
ls-interval-time
|
Specifies the minimum time before a new link state update for a domain will be generated by the switch.
ls-interval-time
is an integer that specifies time in milliseconds. The range is from 0 to 65535.
|
|
region
region-id
|
Specifies the autonomous region to which the switch belongs. The backbone region has region-id=0.
region-id
is an unsigned integer value ranging from 0 to 255.
|
|
spf
|
Specifies parameters related to the shortest path first (SPF) route computation.
|
|
hold-time
spf-holdtime
|
Specifies the time between two consecutive SPF computations. If the time is small, then routing will react faster to changes but CPU usage will be more.
spf-holdtime
is an integer that specifies time in milliseconds. The range is from 0 to 65535.
|
|
static
|
Forces static SPF computation.
|
This command is not applicable to virtual Fibre Channel interfaces.
In FSPF configuration mode, the default is dynamic SPF computation.
If configuring the spf hold-time , the default value for FSPF is 0.
If configuring the min-ls-arrival , the default value for FSPF is 1000 milliseconds.
If configuring the min-ls-interval , the default value for FSPF is 5000 milliseconds.

This command was introduced.
|
The fspf config command enters FSPF configuration mode for the specified Virtual SAN (VSAN). In FSPF configuration mode, the commands configure FSPF for this VSAN.
This example shows how to configure a static SPF computation in VSAN 1 and delete the FSPF configuration in VSAN 3:

|
|
fspf cost
|
Configures the cost for the selected interface in the specified VSAN.
|
|
fspf hello-interval
|
Specifies the hello message interval to verify the health of a link in the VSAN.
|
|
fspf passive
|
Disables the FSPF protocol for the specified interface in the specified VSAN.
|
|
fspf retransmit
|
