Fabric Interconnect connectivity

Caution:

Enabling, disabling, or changing rear port mode, and answering yes to the confirmation prompt,

resets the switch configuration to partial defaults.

When you enable rear port mode, the switch applies the following default settings to all FI ports on

the rear of the chassis:

• VLAN tagging for rear ports is set to tagAll.

• The LACP administration key is set to 4095.

• The LACP operating mode for rear ports is set to active.

• The LACP rear ports time-out value is set to short.

• LACP for rear ports is set to enable.

Note:

Rear port mode allows the VSP 7000 Series to automatically aggregate multiple connections

between adjacent units without additional configuration.

LACP mode is disabled on a rear port if you remove the port from the default VLAN (VLAN 1)

and the port is not configured for any other VLAN. You can activate LACP mode after you add

the port to a VLAN.

When you enable the Shortest Path Bridging (SPB) rear port mode to deploy in a Fabric-mode

DToR, the switch configures port 40 as loopback. Port 40 in loopback mode is not accessible by

applications, or displayed on the port list.

Note:

Rear port Raw-mode does not support SPB. You must enable SPB rear port mode to deploy a

Fabric-mode DToR configuration. Changing between rear port modes results in a reboot and a

partial configuration reset.

Important:

Do not interconnect the FI ports of a VSP 7000 unit operating in Fabric-mode DToR or Raw-

mode with a VSP 7000 unit operating in Stack-mode DToR. This is an invalid configuration that

causes the rear port mode enabled unit to show ports 33–40 as enabled and up, while the Stack

unit ports 33–40 are not visible and not available.
