¹
The hub ID for the Model 1
¹
Management Interface status
¹
Abbreviated text for selected traps
Trap text consists of a numeric value followed by a few descriptive words. All
possible trap messages are documented in “Operational Codes” on page 5-15.
The format of the LCD when the 8239 Model 1 is operational is:
hub_id >unit type value trap_info
management_interface_status > more_trap_info
The LCD is updated every two seconds. A message remains on the LCD until
another condition causes a different message to be displayed. Some messages (for
example, traps and adapter status changes) may not be seen if multiple messages
occur before the LCD is updated.
A description of each line on the LCD when the Model 1 is operational follows.
Line 1:
hub_id >unit type value trap_info
where
hub_id
is a three-character field consisting of two blank spaces
followed by a one-character hub ID of this stack unit.
unit
has a value of 0 if the trap is being reported for a device
external to the stack or is equal to the hub ID if the trap is
being reported for a specific hub.
type
has a value of “E” (error) or “I” (informational).
value
is a 2-digit number identifying the specific trap.
trap_info
further describes the trap using up to seven characters.
Line 2 :
management_interface_status > more_trap_info
where
management_interface_status
is a 3-character code giving the management-interface adapter
status or the ring number. The management-interface adapter status
reflects the state of the token-ring interface used for 8239 in-band
connectivity. These status codes are:
ber
Management Interface exceeded the hub’s beacon
threshold error value.
bwr
Management Interface is beacon-wrapped.
cls
Management Interface is closed.
dwr
Management Interface is in diagnostic wrap mode.
opn
Management Interface is open and unwrapped;
Management Interface is inserted in the ring.
rst
Management Interface is in the reset state.
wrp
Management Interface administrative_mode is disabled;
Management Interface is wrapped. This status code
takes precedence over bwr, cls, and opn.
