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

service tag

To configure a fabricpath OAM service, use the service tag command in fabricpath OAM profile configuration mode. To remove the fabricpath OAM service, use the no form of this command.

service tag tag-id

no service tag tag-id

Syntax Description

tag-id

Service tag ID. The range is from 4096 to 16,777,215.


Command Default

Fabricpath OAM service is not configured.

Command Modes

Fabricpath OAM profile (config-fp-oam-profile)

Command History

Release
Modification

7.0(0)N1(1)

This command was introduced.


Usage Guidelines

The service tag identifies the segment ID.

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

Release
Modification

5.2(1)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)#

Related Commands

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

5.2(1)N1(1)

This command was introduced.


Usage Guidelines

Note The no keyword returns the interface to the default Classical IEEE 802.1Q Ethernet (CE) switchport access interface. The FabricPath ports carry traffic only for those VLANs configured as FabricPath VLANs.

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)#
