Hijacking the Ethernet Port
Static IP is used to create IP connection (e.g., Telnet, SNMP) to A500 switches when
LANE is not available. When LANE is available, LANE is the preferred method to provide
IP connection. On the static IP server, the Network Management System (NMS) is on the
Ether port; there is no instance of an ethernet interface and user defines the static IP
address for the box (Managed Entity). On the Static IP Client, an instance of the ethernet
interface can exist, where the ethernet must be on a subnet other than the NMS subnet.
When static IP is in use, the NMS should be on the same network as the ME, e.g., A500.
If this is not the case, the default gateway must be on the same network as the static IP
address. This applies to both the client and server A500s. This forces the IP traffic to flow
on the static IP interface.
Ethernet Filtering in Promiscuous Mode
To provide static IP, you must place the ethernet interface (physical port) in promiscuous
mode. This mode enables the static IP server to receive unicast MAC frames destined for
static IP clients. To avoid overwhelming the A500 with ethernet traffic, a filter has been
defined to only accept those frames with an OUI matching that of the static IP server.
Configuring Static IP
The Web Agent enables you to configure your static IP configuration, clients, and server.
To configure static IP:
1. In the ATM Switch A500 section of the Web Agent window, select Services, then
select Static IP. The Static IP Status window opens with the Status and Mode
information.
2. Select Configuration. At the Static IP Nvram Configuration screen you can
select Enable or Disable for the Status and Client or Server for the mode.
3. Click Apply to save your changes, or Cancel to restore previous settings.
To configure these connections, using the CLI:
1. In the ATM Switch A500 section of the Web Agent window, select CLI. A shell
window opens.
2. Execute the
admin static_ip enable_client
and
admin static_ip
enable_server
commands. For more information on these commands, see
Chapter 6, "admin Commands".
