Note
The AT-9408LC ⁄SP, AT-9424T/GB, and AT-9424T/SP switches do
not support the IPv4 packet routing feature. These switches do,
however, allow you to create one routing interface so that you can
assign an IP address to the switch for those management functions
that require it. For further information, refer to “AT-9408LC/SP
AT-9424T/GB, and AT-9424T/SP Switches” on page 563.
Note
When an AT-9400 Series switch with an IP address is upgraded
from AT-S63 version 1.3.0 or earlier to the latest version, a routing
interface is automatically created on the device to preserve its IP
configuration. The interface is assigned to the same VLAN that
functioned as the switch’s management VLAN. If the switch does not
have an IP address, no routing interface is created. For further
information, refer to Chapter 32, “Internet Protocol Version 4 Packet
Routing” on page 547.
