Layer 2+ and Basic Layer 3 Switches
The switches in the AT-9400 Gigabit Ethernet Series are divided into two 
groups:
ˆ
Layer 2+ Switches
– AT-9408LC/SP
– AT-9424T/GB
– AT-9424T/SP
ˆ
Basic Layer 3 Switches
– AT-9424T
– AT-9424Ts
– AT-9424Ts/XP
– AT-9448T/SP
– AT-9448Ts/XP
The switches of the two groups offer many of the same features and 
capabilities. However, there are a couple of significant differences. For 
instance, the Internet Protocol Version 4 packet routing feature is only 
supported on the Basic Layer 3 switches and is the reason for the group’s 
name. For a list of the supported features, refer to Table 1. The switches 
are numbered in the table as follows:
Layer 2+ switches:
ˆ
1 - AT-9408LC/SP
ˆ
2 - AT-9424T/GB
ˆ
3 - AT-9424T/SP
Basic Layer 3 switches:
ˆ
4 - AT-9424T
ˆ
5 - AT-9424Ts
ˆ
6 - AT-9424Ts/XP
ˆ
7 - AT-9448T/SP
ˆ
8 - AT-9448Ts/XP
The Stack column lists the features supported in a stack of Basic Layer 3 
switches and the AT-StackXG Stacking Module. For more information, 
refer to “Stacking” on page 44.
