IMPORTANT The zre51 port is the Inter-Switch Link (ISL) for the fabric-side of the switch. If you

plan to connect the fabric portion of each switch into the same external network, do

not include zre51 in this VLAN configuration, as it will create a network loop and

likely bring down the external network. In this case, create a separate VLAN for

zre51 so that the ISL is isolated from the external network.

Step 4. Enter the following command line to move the default script out of the way. This will ensure that

the default script does not execute on the Switch Blade that configures the base interfaces:

mv /etc/rcZ.d/S50layer2 /etc/rcZ.d/off.S50layer2

Step 5. Enter the zsync command to make the rc script persistent:

zsync
