NOTE Make the same set of changes to the redundant, failover Ethernet Switch Blade at
this time in order to maintain High Availability integrity for the 14-Slot Shelf.
Configuring the Fabric Interfaces (zre0 to 51 fabric)
Configure the fabric interfaces on the Ethernet Switch Blade, which will then become vlan5. The sample
topology vlan5 includes fabric ports zre0 through zre51. There is no need to assign an IP address to this
VLAN as it merely passes traffic through to endpoints defined elsewhere in the 14-Slot Shelf. Any fabric
plane traffic to the 14-Slot Shelf will come in through vlan5, which (acting as a switch), will send the traffic to
the appropriate blade in the 14-Slot Shelf.
IMPORTANT When configuring the fabric interfaces on the HP bc2100 ATCA Server Blades, it is important
to note that (in this topology) the Server Blade IP address must to reside within the fabric
network space to ensure proper connectivity to the 14-Slot Shelf and to the outside enterprise.
To build vlan5, complete the following steps:
Step 1. Connect your laptop computer or terminal RS-232 port to the lower (fabric) serial port on the
Switch Blade front panel.
Step 2. Issue the following command to ensure that all fabric interfaces are torn down:
zconfig -t
Step 3. Add the following S50fabric rc script to the /etc/rcZ.d directory to ensure that the fabric
interfaces are recreated when you reboot the Ethernet Switch Blade:
#!/bin/sh
