Ethernet MIB
Your switch supports the Ethernet MIB as defined in Definitions of 
Managed Objects for the Ethernet-like Interface Types, RFC 1284 (J. Cook, 
editor), dated December 1991. 
Bridge MIB
Your switch supports the Bridge MIB as defined in Definitions of Managed 
Objects for Bridges, RFC 1286 (Decker, Langille, Rijsinghani, and 
McCloghrie, editors).
Traps
The unit sends Trap PDUs to the NMS, using the pre-configured NMS IP 
address (see sxadminNMSIPAddr). If no address has been pre-configured, 
then the unit sends the Traps to the source IP address of the last SNMP 
datagram received from an NMS. If no address has been pre-configured, 
and if no datagrams have been received since the unit was booted, then 
the unit uses the broadcast IP address. 
The Trap PDUs are sent from a source UDP port, to a destination UDP 
port, which are the SNMP standard numbers reserved for Trap PDUs. The 
unit may be configured to send an additional copy of each Trap PDU to a 
user specified destination UDP port number (see sysTrapPort).
Generic Traps SNMP defines the generic traps described below. At this time, only generic 
traps are sent.
coldStart (0) The switch has restarted. 
warmStart (1) Not used.
