You can specify two types of tags:
•
•
The LSAN tags are persistently saved and support configupload and configdownload.
Enforce tag
The Enforce tag reduces the resources used in an FC router by limiting the number of LSAN zones
that will be enforced in that FC router.
Use the Enforce tag to achieve better scalability in the FC router. This is useful when multiple FC
routers are connected to the same edge fabric. Without the Enforce tag, all FC routers import all
LSAN zones, even those that are not needed.
Normally, the FC router automatically accepts all zones with names that start with "lsan_". You can
specify an Enforce tag to indicate that a particular FC router should only accept zones that start
with the prefix "lsan_tag". For example, if you specify an Enforce tag of "abc", the FC router accepts
only those LSAN zones that start with "lsan_abc" and does not import or export any other LSAN
zones.
The Enforce tag can be up to eight characters long and can contain only letters and numbers. The
Enforce tag is not case-sensitive; for example, the tag "abc" is equivalent to "ABC" and "Abc".
If you specify "abc", "xyz", and "fab1" as Enforce tags, then the FC router accepts only those LSAN
zones with names that start with any of the following:
In this example, the following LSAN zones would all be accepted:
You can specify up to eight Enforce tags on an FC router.
Speed tag
During target discovery, the FC router process of presenting proxy devices and setting up paths to
the proxy devices may cause some sensitive hosts to time out or fail. The Speed tag allows you to
speed up the discovery process by importing the devices into the remote edge fabrics when the
devices come online, regardless of the state of the host. This helps sensitive hosts to quickly
discover the devices without timing out.
You set the Speed tag on the FC router, and then configure the LSANs in the target edge fabrics
with the tag.
For example, in
devices D1 and D2. You could set up the Speed tag as follows:
1. In FC router 1 and FC router 2, configure the Speed tag as "super".
2. In Edge fabric 2, configure two LSANs:
