Chapter 2: Ethernet Line Cards
54 Section I: Hardware Overview
 Large Layer 2 Switching and Layer 3 Routing mode - Optimizes
AT-SBx81XLEM Line Cards for remote Layer 3 subnets.

Large Layer 3 Host mode - Optimizes AT-SBx81XLEM Line Cards
for local Layer 3 hosts.
Here are the guidelines for the large address table modes:
 The large table modes are supported only when the AT-SBx8106
Chassis has AT-SBx81XLEM Line Cards. The large table modes
are not supported with any of the other SwitchBlade x8100
Ethernet line cards.

You have to specify the silicon profile “profile3” for the chassis with
the PLATFORM SILICON-PROFILE command in the AlliedWare
Plus operating system.
Caution
Profile3 is only compatible with AT-SBx81XLEM Line Cards. Do not
activate the profile if the chassis contains other models of
SwitchBlade x8100 Ethernet line cards.

Only one large table mode can be active at a time in a chassis.

The large table mode is set at the chassis level. All AT-
SBx81XLEM Line Cards in the chassis use the same table mode
setting.

The SFP+ slots on the front panel of the AT-SBx81CFC960
Controller Fabric Card cannot be used for regular network traffic
when silicon profile Profile3 is active. They must be unused or
used for the trunk in a VCStack Plus. The AlliedWare Plus
operating system disables the SFP+ slots for regular network
traffic when you designate “profile3” as the silicon profile for the
chassis.

The large address table modes require AlliedWare Plus v5.4.6.1-1
or later.
 Using the large table modes is optional.
 The large table modes require the AT-SBx81CFC960 Controller
Fabric Card. The AT-SBx81CFC400 Controller Fabric Card does
not support the large table modes.
For descriptions of the large table modes and how to activate them, refer
to “Command Reference: SwitchBlade x8100 Series Switches running
AlliedWare Plus Version 5.4.6-1.x.”
LEDs
Each SFP slot on the AT-SBx81XLEM Line Card has one LED. The LED
is shown in Figure 26 on page 55 and described in Table 13 on page 55.
