S Commands


This chapter describes the Cisco NX-OS FabricPath commands that begin with S.

spf-interval

To configure an interval for shortest-path-first (SPF) generation, use the spf-interval command. To return to the default setting, use the no form of this command.

spf-interval {spf-max-wait | spf-initial-wait | spf-second-wait}

no spf-interval {spf-max-wait | spf-initial-wait | spf-second-wait}

Syntax Description

spf-max-wait

Maximum interval (in seconds) between two consecutive occurrences of a link-state packet (LSP) being generated. The range is from 50 to 120000.

spf-initial-wait

Initial LSP generation delay (in milliseconds). The range is from 50 to 120000.

spf-second-wait

Hold time between the first and second LSP generation (in milliseconds). The range is from 50 to 120000.


Command Default

The defaults are as follows:

spf-max-wait: 8000

spf-initial-wait: 50

spf-second-wait: 50

Command Modes

FabricPath IS-IS configuration mode

Command History

Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to configure an interval for SPF generation:

switch# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
switch(config)# fabricpath domain default
switch(config-fabricpath-isis)# spf-interval 9000 60 70
switch(config-fabricpath-isis)#

Command
Description

fabricpath domain default

Enables FabricPath Layer 2 IS-IS.


switchport mode fabricpath

To configure interfaces as FabricPath ports, use the switchport mode fabricpath command. To return the interfaces to the default settings, use the no form of this command.

switchport mode fabricpath

no switchport mode

Syntax Description

This command has no arguments or keywords.

Command Default

None

Command Modes

Interface configuration mode
Virtual Ethernet interface configuration mode

Command History

Release
Modification

6.0(2)N1(1)

This command was introduced.

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to configure specific interfaces as FabricPath ports:

switch# configure terminal
switch(config)# interface ethernet 2/11-15
switch(config-if)# switchport mode fabricpath
switch(config-if)# no shutdown
switch(config-if)#
 
   

This example shows how to configure a virtual Ethernet interface as a FabricPath port:

switch# configure terminal
switch(config)# interface vethernet 1
switch(config-if)# switchport mode fabricpath
switch(config-if)# no shutdown
switch(config-if)#
