42 Chapter 1 BayStack 420 Switch
209418-A
SNMP trap support
The BayStack 420 Switch supports an SNMP agent with industry standard
SNMPv1 traps, as well as private SNMPv1 trap extensions (Table 6).
BootP automatic IP configuration/MAC address
The BayStack 420 Switch has a unique 48-bit hardware address, or MAC address,
that is printed on a label on the back panel. You use this MAC address when you
configure the network BootP server to recognize the BayStack 420 Switch BootP
requests. A properly configured BootP server enables the switch to automatically
learn its assigned IP address, subnet mask, IP address of the default router (default
gateway), and software image file name.
For information on a stack MAC address, see “Stack MAC address” on page 50.
For more information and an example of a BootP configuration file, see
Appendix F, “Sample BootP configuration file,” on page 207.
