BayStack 450 10/100/1000 Series Switches
309978-D Rev 01 1-17
SNMP Traps
The BayStack 450 switch supports an SNMP agent with industry-standard
SNMPv1 traps, as well as private SNMPv1 trap extensions (
Table 1-3).
Security
Your BayStack 450 switch security feature can provide four levels of security for
your local area network (LAN):
• “MAC Address-Based Security” (page 1-20) -- Limits access to the switch
based on allowed source MAC addresses.
• “EAPOL-Based Security” (page 1-21) -- Limits access to the switch based on
an authentication mechanism that uses Extensible Authentication Protocol
(EAP) to exchange authentication information between the switch and an
authentication server.
