You can also use the ping command to specify additional ping parameters,
including the number of ICMP packets to be sent, the packet size, the
interval between packets, and the timeout. You can also set the ping to
continuous, or you can set a debug flag to obtain extra debug information.
For more information about these commands, see "System configuration
using the CLI" (page 177).
BootP automatic IP configuration/MAC address
The Ethernet Routing Switch 2500 Series has a unique 48-bit hardware
address, or MAC address, that is printed on a label on the back panel. You
can use this MAC address when you configure the network BootP server
to recognize the Ethernet Routing Switch 2500 Series BootP requests. A
properly configured BootP server lets the switch automatically learn its
assigned IP address, subnet mask, IP address of the default router (default
gateway), and software image file name.
For more information and an example of a BootP configuration file, see
Appendix "Sample BootP configuration file" (page 351).
Choosing a BootP request mode
The BootP Request Mode field in the IP Configuration window lets you
choose which method the switch uses to broadcast BootP requests:
• BootP or Default IP
•
BootP Always
•
BootP Disabled
