Frequently asked questions

This chapter provides answers to frequently asked questions about SFS.

• Can I use different platforms in the same VLT leaf pair in a fabric?

  No, both leaf switches in the same VLT pair must be the same platforms in SFS deployments. See Networking Solutions Support Matrix for the list of supported switches and typical roles in SFS deployments.

• Can I use the different switch port profiles available on S4148F-ON in SmartFabric mode?

  Yes, all six profiles available on S4148F-ON can be used in SmartFabric mode as follows:

  1. Set the appropriate port profile for the switch in Full-Switch mode.
     CAUTION Changing the switch port profile resets the system defaults and overwrites the existing switch configuration. You must reconfigure the setting on a switch manually after applying the new port profile.
  2. Reload the switch to apply the new port profile.
  3. Enable SFS on the switch to change the switch mode to SmartFabric. After enabling SFS, the switch reboots in SmartFabric mode and uses the set port profile.
  NOTE For more information about port profiles, see SmartFabric OS10 User Guide. This procedure is applicable only on S4148F-ON platform as S4148FE-ON and S4148U-ON switches are not supported in SFS deployments.
• How do I change the OS10 admin password in SmartFabric mode?

  By default, admin is the username and password to log in to the OS10 CLI. The default OS10 admin password should be changed on each switch after the first login. The procedure is the same for a switch in Full Switch mode or SmartFabric mode. For more information about changing the password, see SmartFabric OS10 User Guide. The admin password does not have to be the same password on all switches in a SFS deployment. When logging in to the SFS GUI, use the credentials of the leader switch. The leader switch may change and use the command show smartfabric cluster at any switch in the SmartFabric to see the details of the leader switch.

• How can I upgrade firmware for a SFS-enabled switch?

  The firmware can be upgraded using the image install command. For more information about installing firmware upgrade, see SmartFabric OS10 User Guide.

• Can I have a peer switch with multiple BGP devices?

  Yes, you can peer SFS switches with multiple BGP devices.

• Is OSPF supported for SFS?

  No. OSPF is not supported in SFS with leaf and spine deployments.

• How many jump ports can I configure?

  You can configure one jump port per leaf switch in a fabric.

• Can I change the VLTi interface after SFS has been enabled?

  There is no option to change the VLTi interface in SmartFabric mode. If you want to change the VLTi interfaces, the leaf switches must be changed from SmartFabric mode to Full-Switch mode using the no smartfabric l3fabric command. This command deletes all the existing configuration on the switches. Enable SmartFabric mode back on the leaf switches and specify the new VLTi interfaces with the smartfabric l3fabric enable role LEAF vlti ethernet command, see here.
