Configuring FCR router port cost
In FCR, EX_Ports can be assigned router port cost. The cost of the link is a positive number. The
router port path or tunnel path is chosen based on the minimum cost per connection. If multiple paths
exist with the same minimum cost, there will be load sharing over these paths. If multiple paths exist
where one path costs less than the others, then the lowest cost path is used.
Every link has a default cost. For an EX_Port 1 Gbps, 2 Gbps, 4 Gbps, 8 Gbps, 10 Gbps, and 16 Gbps
links, the default cost is 1000. For a VEX_Port, the default cost is 10000. If the cost is set to 0, the
default cost are be used for that link.
To configure the FCR router port cost, perform the following steps.
1. Click Configure > FCR.
2. Click the EX_Ports tab.
3. Disable the EX_Port.
4. Click the Router Port Cost button.
Viewing LSAN zones
The LSAN Zones tab displays all the LSAN zones, in both a tabular and tree form. If FC-FC Routing is
disabled, the table and the tree node in this tab display only the LSAN zones present in the backbone
fabric.
For more detailed information about a specific LSAN zone, click a zone name in the table and then
click the View Details button in the task bar. You can also click the zone name in the tree on the left
side of the window.
The LSAN matrix is mapping of LSAN Zones with the edge fabric they are going to communicate with.
When an LSAN matrix is created in the backbone fabric, only the LSAN zones mapped in the edge
fabrics are displayed in the LSAN Zones tab.
Follow the procedure described in Creating and populating zones on page 148 to create LSAN zones.
Viewing LSAN devices
The LSAN Devices tab displays information about the physical and proxy devices and displays these
devices in a tree on the left side of the window. (If FC-FC Routing is disabled, the tables and tree
nodes in this tab are empty.)
Click the LSAN Devices element in the tree to display a count of all the physical and proxy LSAN
devices. Note that this count is for all of the LSAN fabrics.
Click the Physical Devices or Proxy Devices element in the tree to see a detailed list of the physical
or proxy devices. Click the device name in the tree for more detailed information about a specific
device.
