"INTRODUCTION"





This document describes the SNMP Trap messages that are currently being
sent by Timeplex network devices to the Element Management Station (EMS).
The SNMP Trap messages are divided into 2 groups: generic and specific. Generic
traps are those defined in RFC 1067. Timeplex network devices comply with
the standard as well as providing additional information to further clarify
the generic trap. Specific traps are used to identify events that are
specific to Timeplex network devices. Here again, additional information is
provided to clarify the specific trap.



"GENERIC TRAPS"



An SNMP Trap message as defined in RFC 1067 contains a field named 'generic'.
The value of this field indicates the type of generic trap. Timeplex network
devices use the field named 'specific' to convey additional information
clarifying the generic trap. RFC 1067 does not restrict the use of this field
for generic traps. There are 32 bits available in the 'specific' field. The
following defines the generic traps together with the values of their respective
'generic' and 'specific' fields:


COLDSTART TRAP

Cause: issued upon power-up.
Generic field: 0
Specific field: 0


WARMSTART TRAP

Cause: issued after a network device has reset due to some unrecoverable
error condition.
Generic field: 1
Specific field: process ID (bits 8-15)
error code (bits 0-7)

LINKDOWN TRAP

Cause: issued after a network link interface (LAPB) has been declared down.
Generic field: 2
Specific field: reason (bits 30-31)
0 = scheduled
1 = link error
2 = indeterminate
3 = frame reject
state information (bits 0-23)

LINKUP TRAP

Cause: issued after a network link interface (LAPB) has been declared up.
Generic field: 3
Specific field: initial UP (bit 31)
0 = TRUE
1 = FALSE

AUTHENTICATION FAILURE TRAP

Cause: issued whenever SNMP receives an SNMP request message that
is not from the EMS or has an invalid community name.
Generic type: 4
Specific type: IP address in network byte order of the source
of the invalid SNMP request


EGP NEIGHBOR LOSS TRAP

Cause: issued whenever EGP detects that one of his neighbors is
no longer responsive.
Generic type: 5
Specific type: IP address in network byte order of the EGP neighbor
that is mo longer responsive

"SPECIFIC TRAPS"



The specific trap type is meaningful only when the generic trap type is SPECIFIC (=6).
In other words, if an SNMP Trap message contains a 'generic' value of 6, them the
'specific' value identifies the specific trap type. The lower 8 bits identify the
specific trap type; the upper 24 bits contain information to further clarify the
specific trap. The following defines the specific trap types:


FDDI SCM STATE CHANGE TRAP

Cause: issued when a station wraps or unwraps
Lower 8 bits: 151
Upper 24 bits: Station state [1-4] in bits 15-8
1 = Isolated (will not be transmitted over the network)
2 = Wrap A
3 = Wrap B
4 = Thru
6 = Cleave A (wrap A for Dual Home
operation)
7 = Cleave B (wrap B for Dual Home
operation)


FDDI UPSTREAM NEIGHBOR CHANGE TRAP

Cause: issued when a station detects a new upstream neighbor
has been connected to the ring.
Lower 8 bits: 152
Upper 24 bits: not used


FDDI DOWNSTREAM NEIGHBOR CHANGE TRAP

Cause: issued when a station detects that a new downstream neighbor
has been connected to the ring.
Lower 8 bits: 153
Upper 24 bits: not used


FDDI CONNECT REJECTED TRAP

Cause: issued when the station PHY rejects a neighbor PHY connection.
Lower 8 bits: 154
Upper 24 bits: PHY resource index [1-10] in bits 23-16
reject code [2-6] in bits 15-8
2 = Neighbor Station Reject
3 = Connect Ports Incompatible
4 = Exceesive Bit Errors on link
5 = Neighbor Station Detected
Excessive Bit Erros
6 = Master Port to Master Port
Connect Reject


DUPLICATE MAC ADDRESS
Cause: issued when a station detects when another station on
the ring has the same physical(MAC) address as the this
issuing station.
Lower 8 bits: 155
Upper 24 bits: not used


UNA DUPLICATE MAC ADDRESS
Cause: issued when this station's upstream neighbor station
detects that it has a duplicate MAC address.
Lower 8 bits: 156
Upper 24 bits: not used


FDDI TWISTED RING
Cause: issued when a station detects that its PHY A/B is
connected to a matching PHY A/B causing the ring to twist back on itself.
Lower 8 bits: 157
Upper 24 bits: not used


SLAVE LINK ERROR TRAP
Cause: issued when a concentrator detects that one of its slave
links has exceed its CRC error rate threshold.
Lower 8 bits: 158
Upper 24 bits: Slave port [1-8] in bits 15-8
