Changing the Maximum Number of Hops to a BootP Relay Server

Each BootP/DHCP request includes a field Hop Count field. The Hop Count field indicates how many routers the request has passed through. When the routing switch receives a BootP/DHCP request, the routing switch looks at the value in the Hop Count field.

If the hop count value is equal to or less than the maximum hop count the routing switch allows, the routing switch increments the hop count by one and forwards the request.

If the hop count is greater than the maximum hop count the routing switch allows, the routing switch discards the request.

To change the maximum number of hops the routing switch allows for forwarded BootP/DHCP requests, use either of the following methods.

NOTE: The BootP/DHCP hop count is not the TTL parameter.

USING THE CLI

To modify the maximum number of BootP/DHCP hops, enter the following command:

HP9300(config)# bootp-relay-max-hops 10

This command allows the routing switch to forward BootP/DHCP requests that have passed through up to ten previous hops before reaching the routing switch.

Syntax: bootp-relay-max-hops <1-15>

USING THE WEB MANAGEMENT INTERFACE

To modify the maximum number of hops supported:

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 display the list of configuration options.

3.Click on the plus sign next to IP to display the list of IP configuration options.

4.Select the General link to display the IP configuration panel.

5.Enter a value from 1 – 15 in the BootP Relay Maximum Hop field.

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.
