CHAPTER 7
TRAPS
The unit sends Trap PDUs to the NMS, using the pre-configured
NMS IP address (see lxadminNMSIPAddr). 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 source UDP port number 161, to
destination UDP port number 162, 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).

7.1 GENERIC TRAPS
The ELS10-26 issues generic and enterprise-specific (Cabletron)
traps. SNMP defines the generic traps below.
coldStart (0) - The ELS10-26 has restarted.
warmStart (1) - Not used by the ELS10-26.
linkDown (2) - A port has failed, and ELS10-26’s response is to
automatically disable usage of the port. If the port comes back to
life, ELS10-26 will automatically re-enable usage of the port. The
“variable-bindings” portion of the trap contains the ifIndex of the
port.
linkUp (3) - A port has come back to life, and the ELS10-26’s local
management agent has re-enabled usage of the port. The
“variable-bindings” portion of the trap contains the ifIndex of the
port.

The additional traps are not sent when the ELS10-26 is using the broadcast IP
address.
