Gateway Address field of BootP/DHCP requests that the Layer 3 Switch receives on port 1/1 and forwards to the
BootP/DHCP server.
Syntax: ip bootp-gateway <ip-addr>
USING THE WEB MANAGEMENT INTERFACE
You cannot change the IP address used for stamping BootP/DHCP requests using the Web management
interface.
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 Layer 3 Switch receives a BootP/DHCP request, the Layer 3 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 Layer 3 Switch allows, the Layer 3
Switch increments the hop count by one and forwards the request.
• If the hop count is greater than the maximum hop count the Layer 3 Switch allows, the Layer 3 Switch
discards the request.
To change the maximum number of hops the Layer 3 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:
BigIron(config)# bootp-relay-max-hops 10
This command allows the Layer 3 Switch to forward BootP/DHCP requests that have passed through up to ten
previous hops before reaching the Layer 3 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.
