Standard is a Raw-mode, that can support various port configurations and protocols, such as
Inter-Switch Trunking (IST) for Switch Clustering.
Figure 23: FI port labels
Note:
Due to the different bandwidth support of the FI port top and bottom connectors, you must
connect the top connector to the top connector of another unit, and connect the bottom
connector to the bottom connector of another unit.
Rear port mode is disabled by default. With rear port mode disabled, the FI ports on the rear
of the chassis can be interconnected between units to deploy in a Stack-mode DToR.
Note:
When you enable, disable, or modify a rear port mode, the switch automatically initiates a
reboot.
Warning:
Enabling, disabling, or changing rear port mode and answering yes to the confirmation
prompt results in a switch configuration reset equivalent to a partial default command.
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 once
you add the port to a VLAN.
