This command was introduced.

5.0(2)N2(1)

Support for virtual Fibre Channel interface was added.


Usage Guidelines

By default, FSPF is enabled on all E ports and TE ports of an Fibre Channel over IP (FCIP) interface. FSPF can be disabled by setting the interface as passive using the fspf passive command. FSPF must be enabled on the ports at both ends of the ISL for the protocol to operate correctly.

For virtual Fibre Channel interfaces, this command configures the FSPF parameters for the virtual E (VE) port.

Examples

This example shows how to disable the FSPF protocol for an FCIP interface on VSAN 1:

switch(config)# interface fc 2/1 
switch(config-if)# fspf passive vsan 1 

This example shows how to disable the FSPF protocol for a virtual Fibre Channel interface on VSAN 1 and verify the interface configuration:

switch(config)# interface vfc 5 
switch(config-if)# fspf passive vsan 1 
switch(config-if)# show fspf interface 
FSPF interface vfc5 in VSAN 1
FSPF routing administrative state is passive
Timer intervals configured, Hello 30 s, Dead 300 s, Retransmit 5 s
FSPF State is DOWN

switch(config-if)#
