¹
A terminal interface command using a Telnet session to an 8239 Model 1 in the
stack
¹
An SNMP request to the appropriate object in the 8239 MIB issued to an 8239
Model 1 in the stack
Instructions for accessing information in the remainder of this chapter describe only
access through the terminal interface command.
Methods of Viewing Traps
The methods by which you can view trap information are:
¹
Displaying the trap on the terminal interface (EIA-232 interface or, on an 8239
Model 1 only, a Telnet session)
¹
Storing the trap in a trap log that can be displayed on your request
¹
Displaying the trap on the LCD (8239 Model 1 only)
¹
Sending the trap to an SNMP application (8239 Model 1 only)
The method used is governed by the 8239 configuration settings referred to as
trap
flags. For further information about trap flags, see “Configuring for Trap Generation
and Accessing Trap Information” on page 7-12.
Displaying Traps on the Terminal Interface
You access the 8239 terminal command interface by logging in via the 8239’s
EIA-232 interface or a Telnet session. Telnet is supported by the 8239 Model 1
only. For more information on the terminal interface, refer to “Using the Command
Interface” on page 4-1. You can display traps at a remote console that is
connected by either the EIA-232 interface or a Telnet session.
To display traps on the terminal interface you must configure the 8239 with
console_display enabled. The factory setting for console_display is enabled. To
change the console_display setting, issue the ENABLE/DISABLE TRAP_SETTING
CONSOLE_DISPLAY terminal interface command. To display the current setting for
console_display, issue the DISPLAY TRAP_SETTINGS terminal interface
command. Even when console_display is enabled, other trap flag settings can
prevent the trap from being displayed.
Logging Traps
Each 8239 stores traps in a log that is maintained locally so that a history of the
traps that were generated can be obtained easily. The trap log contains up to 64 of
the most recent traps that were generated.
Only the traps that have their associated trap flag enabled are stored in the trap
log. For example, all of the items listed under DISPLAY TRAP_SETTINGS except
for "console_display" are considered to be trap flags. For more information about
the individual trap flags, refer to “Configuring for Trap Generation and Accessing
Trap Information” on page 7-12.
To display the trap log, issue the DISPLAY TRAP_LOG terminal interface
command. The trap log is cleared whenever the 8239 is reset or the CLEAR
TRAP_LOG terminal interface command is issued.
