Configuring IP

USING THE WEB MANAGEMENT INTERFACE

1.Log on to the device using a valid user name and password for read-write access. The System configuration panel is displayed.

2.Click on the plus sign next to Configure in the tree view to expand the list of configuration options.

3.Click on the plus sign next to IP in the tree view to expand the list of IP option links.

4.Click on the General link to display the IP configuration panel.

5.Select the Disable or Enable radio button next to Broadcast Forward.

6.Click the Apply button to save the change to the device’s running-config file.

7.Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change to the startup-config file on the device’s flash memory.

NOTE: To define the ports to be forwarded, select the UDP Helper link from the IP configuration sheet.

Configuring an IP Helper Address

To forward a client’s broadcast request for a UDP application when the client and server are on different networks, you must configure a helper address on the interface connected to the client. Specify the server’s IP address or the limited broadcast address of the IP sub-net the server is in as the helper address.

You can configure up to four helper addresses on each interface. You can configure a helper address on an Ethernet port or a virtual interface. To configure a helper address, use either of the following methods.

USING THE CLI

To configure a helper address on interface 2 on chassis module 1, enter the following commands:

HP9300(config)# interface e 1/2

HP9300(config-if-1/2)# ip helper-address 1 207.95.7.6

The commands in this example change the CLI to the configuration level for port 1/2, then add a helper address for server 207.95.7.6 to the port. If the port receives a client request for any of the applications that the routing switch is enabled to forward, the routing switch forwards the client’s request to the server.

Syntax: ip helper-address <num> <ip-addr>

The <num> parameter specifies the helper address number and can be from 1 – 4. Thus, an interface can have up to four helper addresses.

The <ip-addr> command specifies the server’s IP address or the limited broadcast address of the IP sub-net the server is in.

USING THE WEB MANAGEMENT INTERFACE

To configure a helper address on an interface:

1.Log on to the device using a valid user name and password for read-write access. The System configuration panel is displayed.

2.Click on the plus sign next to Configure in the tree view to expand the list of configuration options.

3.Click on the plus sign next to RIP in the tree view to expand the list of RIP option links.

4.Click on the UDP Helper link.

If the device does not have any UDP helper assignments, the UDP Helper configuration panel is displayed, as shown in the following example.

If a UDP helper assignment is already configured and you are adding a new one, click on the Add UDP Helper link to display the UDP Helper configuration panel, as shown in the following example.

If you are modifying an existing UDP helper assignment, click on the Modify button to the right of the row describing the assignment to display the UDP Helper configuration panel, as shown in the following example.
