58 CHAPTER 4: CREATING AN XRN STACKING FABRIC
Table 14 SuperStack 4 Switch 5500 Support for XRN Distributed Fabric
1 Ensure that the Switch units that you wish to interconnect have the latest
software agent installed. You can use the display version
command to check this.
2 Enable the ‘up port’ and the ‘down port’ on each Switch (see Ta b le 14
) to
operate in Fabric mode using the following CLI command. From the
System View enter fabric-port gigabitethernet 1/0/51
enable, for example.
As with all Switch 5500 CLI commands, the format for entering a
command that is port specific is x/y/z, where x = unit number, y = module
number (in the case of the Switch 5500 this will always be 0), z = port
number.
3 Connect the Fabric-enabled ‘up’ port on one Switch 5500 unit to the
Fabric-enabled ‘down’ port on another Switch 5500 unit using the
appropriate connection method for your Switch as detailed in Tab l e 14
.
4 To create a fully resilient Fabric: enable the spare Fabric ports on the
top-most and bottom-most units in the Fabric as described in the
previous steps. Then insert a cable into these two Fabric ports to create a
link between the top-most and bottom-most units in the Fabric, as shown
in Figure 17
on page 60.
This ensures that in the event of a unit failure within the Fabric, the Fabric
will continue working and no “Fabric split” will occur.
5 Save all configuration settings. From the User View, enter the save
command to save the configuration to your Switch.
