AT-S63 Management Software Command Line Interface User’s Guide
Section VII: Internet Protocol Routing 567
The following command creates a default route for the example and
specifies the next hop as 149.44.55.6:
add ip route=0.0.0.0 nexthop=149.44.55.6
Upgrading from
AT-S63 Version
1.3.0 or Earlier
When an AT-9400 Series switch running AT-S63 version 1.3.0 or earlier is
upgraded to the latest version of the management software, the unit
retains its previous IP configuration by automatically creating a routing
interface that replicates the configuration. If the switch had a static
address, the interface is assigned the same address. If the unit obtained
its IP configuration from a DHCP or BOOTP server, the interface is
created with its DHCP or BOOTP client activated. The interface is given
the interface number 0 and assigned to the preexisting management
VLAN. Furthermore, the interface is designated as the local interface of
the switch.
For example, a switch with the static IP address 149.55.55.55, subnet
mask 255.2552.255.0, and a management VLAN with a VID of 12 will
have, after the upgrade, a routing interface with the name VLAN12-0 and
the same static IP address and subnet mask.
The purpose of retaining the IP configuration is to ensure that those
management functions (e.g., remote Telnet management, syslog client,
and RADIUS client) that were operating before the upgrade will continue to
operate after the unit is upgraded to the newest version of the
management software. Without this feature, you would have to restore the
switch’s IP configuration by manually creating a routing interface.
If the switch does not have an IP address and the DHCP and BOOTP
clients are not activated, the upgrade process does not create a routing
interface.
