FIGURE 90 Example of setting up Speed LSAN tag
Rules for LSAN tagging
Note the following rules for configuring LSAN tags:
• You configure the tags on the FC router, and not on the edge switches. If Virtual Fabrics is enabled,
you configure the tags on the base switch on which the EX_Ports and VEX_Ports are located. You
then must ensure that the LSAN zones in the edge fabrics incorporate the tags correctly.
• The LSAN tags are configured per FC router, not per fabric. If the backbone fabric has multiple FC
routers, it is recommended that you configure the LSAN tags on all of the FC routers.
• The FC router must be disabled before you configure the Enforce tag. Configuring the Speed tag
does not require that the FC router be disabled; however, after configuring the Speed tag, you must
select the host or target port to trigger the fast import process.
• The tag is from 1 through 8 alphanumeric characters.
• You can configure only one Speed tag on an FC router, and up to eight Enforce tags on an FC
router. The maximum number of tags (Enforce and Speed) on an FC router is eight.
• Up to 500 Speed LSAN tags are supported.
Configuring an Enforce LSAN tag
1. Log in to the FC router as admin.
2. Enter the following command to disable the FC router:
switchdisable
3. Enter the following command to create an Enforce LSAN tag:
fcrlsan --add -enforce tagname
The tagname variable is the name of the LSAN tag you want to create.
