Setting the maximum LSAN count You can set the maximum number of LSAN zones, or LSAN count, that can be configured on the edge fabrics. By default, the maximum LSAN count is set to 3000. You can increase the maximum LSAN count to 5000 without disabling the switch. The maximum number of LSAN devices supported is 10000 (this includes both physical and proxy devices). If you have 3000 LSAN zones but have not exceeded the 10000 device limit, you can increase the LSAN count to 5000. All FC routers in the same backbone fabric should have the same maximum LSAN count defined, to prevent the FC routers from running into indefinite state. Asymmetric LSAN configurations due to different maximum LSAN counts could lead to different devices being imported on different FC routers. 1.

On the FC router, the host and Target A are imported, because both are defined by
lsan_zone_fabric2
and
lsan_zone_fabric75
. However, target B is defined by
lsan_zone_fabric75
and is not imported because
lsan_zone_fabric2
does not allow it.
When a PLOGI, PDISC, or ADISC arrives at the FC router, the SID and DID of the frame are checked.
If they are LSAN-zoned at both SID and DID edge fabrics, the frame is forwarded to the DID. If they
are not zoned, only the PLOGI is dropped; for the remaining frames zoning enforcement takes
place in the edge fabrics.
Setting the maximum LSAN count
You can set the maximum number of LSAN zones, or LSAN count, that can be configured on the
edge fabrics. By default, the maximum LSAN count is set to 3000. You can increase the maximum
LSAN count to 5000 without disabling the switch.
The maximum number of LSAN devices supported is 10000 (this includes both physical and proxy
devices). If you have 3000 LSAN zones but have not exceeded the 10000 device limit, you can
increase the LSAN count to 5000.
All FC routers in the same backbone fabric should have the same maximum LSAN count defined, to
prevent the FC routers from running into indefinite state. Asymmetric LSAN configurations due to
different maximum LSAN counts could lead to different devices being imported on different FC
routers.
