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).

Table 6 Support SNMP traps

Trap name	Configurable	Sent when
RFC 1215 (industry standard):
linkUp	Per port	A port’s link state changes to up.
linkDown	Per port	A port’s link state changes to down.
authenticationFailure	System wide	There is an SNMP authentication failure.
coldStart	Always on	The system is powered on.
warmStart	Always on	The system restarts due to a management
		reset.
s5CtrMIB (Nortel proprietary traps):
s5CtrUnitUp	Always on	A unit is added to an operational stack.
s5CtrUnitDown	Always on	A unit is removed from an operational stack.
s5CtrHotSwap	Always on	A unit is hot-swapped in an operational
		stack.
s5CtrProblem	Always on	An assigned base unit fails.
s5EtrSbsMacAccessViolation	Always on	A MAC address violation is detected.

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.
