show context
To display information stored in NVRAM when an unexpected system reload (system exception) occurs, use the show context command in user EXEC or priviledged EXEC mode.
show context [summary | all | slot slot-number [crash-index] [all] [debug]]
Syntax Description
Command Modes
User EXEC
Privileged EXEC
Command History
10.3
This command was introduced.
11.2 GS
The slot slot-number [crash-index] [all] [debug] syntax was added for Cisco 12000 series routers.
Usage Guidelines
The display from the show context command includes the following information:
•
Reason for the system reboot
•
•
•
•
Note
Output for this command will vary by platform. Context information is specific to processors and architectures. For example, context information for the Cisco 2600 series router differs from that for other router types because the Cisco 2600 runs with an M860 processor.
Examples
The following is sample output from the show context command following a system failure:

show derived-config
To display the composite results of all the configuration commands that apply to an interface, including commands that come from sources such as static templates, dynamic templates, dialer interfaces, and authentication, authorization, and accounting (AAA) per-user attributes, use the show derived-config command in privileged EXEC mode.
show derived-config [interface type number]
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Configuration commands can be applied to an interface from sources such as static templates, dynamic templates bound by resource pooling, dialer interfaces, AAA per-user attributes and the configuration of the physical interface. The show derived-config command displays all the commands that apply to an interface.
The output for the show derived-config command is nearly identical to that of the show running-config command. It differs when the configuration for an interface is derived from a template, a dialer interface, or some per-user configuration. In those cases, the commands derived from the template, dialer interface, and so on, will be displayed for the affected interface.
If the same command is configured differently in two different sources that apply to the same interface, the command coming from the source that has the highest precedence will appear in the display.
Examples
The following examples show sample output for the show running-config and show derived-config commands for serial interface 0:23 and dialer interface 0. The output of the show running-config and show derived-config commands is the same for dialer interface 0 because none of the commands that apply to that interface are derived from any sources other than the configuration of the dialer interface. The output for the show running-config and show derived-config commands for serial interface 0:23 differs because some of the commands that apply to serial interface 0:23 come from dialer interface 0.

Command History
Usage Guidelines
The availability of keywords will depend on your system.
Once a minute a routine is run that gets environmental measurements from sensors and stores the output into a buffer. This buffer is displayed on the console when the show environment command is entered.
If a measurement exceeds desired margins, but has not exceeded fatal margins, a warning message is printed to the system console. The system software queries the sensors for measurements once a minute, but warnings for a given test point are printed at most once every hour for sensor readings in the warning range and once every 5 minutes for sensor readings in the critical range. If a measurement is out of line within these time segments, an automatic warning message appears on the console. As noted, you can query the environmental status with the show environment command at any time to determine whether a measurement is at the warning or critical tolerance.
If a shutdown occurs because of detection of fatal environmental margins, the last measured value from each sensor is stored in internal nonvolatile memory.
For environmental specifications, refer to the hardware installation and configuration publication for your individual chassis.
If the Cisco 12000 series exceeds environmental conditions, a message similar to the following is displayed on the console:
%GSR_ENV-2-WARNING: Slot 3 Hot Sensor Temperature exceeds 40 deg C;Check cooling systems
Note
You can also enable Simple Network Management Protocol (SNMP) notifications (traps or informs) to alert a network management system (NMS) when environmental thresholds are reached using the snmp-server enable traps envmon and snmp-server host global configuration commands.
Whenever Cisco IOS software detects a failure or recovery event from the DRPS unit, it sends an SNMP trap to the configured SNMP server. Unlike console messages, only one SNMP trap is sent when the failure event is first detected. Another trap is sent when the recovery is detected.
Cisco AS5300 DRPS software reuses the MIB attributes and traps defined in CISCO-ENVMON-MIB and CISCO-ACCESS-ENVMON-MIB. CISCO-ENVMON-MIB is supported by all Cisco routers with RPS units, and CISCO-ACCESS-ENVMON-MIB is supported by the Cisco 3600 series routers.
A power supply trap defined in CISCO-ENVMON-MIB is sent when a failure is detected and when a failure recovery occurs for the following events: input voltage fail, DC output voltage fail, thermal fail, and multiple failure events.
A fan failure trap defined in CISCO-ENVMON-MIB is sent when a fan failure or recovery event is detected by Cisco IOS software.
A temperature trap defined in CISCO-ACCESS-ENVMON-MIB is sent when a board overtemperature condition is detected by Cisco IOS software.
CISCO-ACCESS-ENVMON-MIB also defines an overvoltage trap. A similar trap is defined in CISCO-ENVMON-MIB, but it requires the ciscoEnvMonVoltageStatusValue in varbinds. This value indicates the current value of the voltage in the RPS. With Cisco AS5300 RPS units, the current voltage value is not sent to the motherboard.
CISCO-ENVMON-MIB is extended to add a new enumerated value, internalRedundant(5), for MIB attribute ciscoEnvMonSupplySource. This is used to identify a RPS unit.
Examples
In the following example, the typical show environment display is shown when no warning conditions are in the system for the Cisco 7000 series and Cisco 7200 series routers. This information may vary slightly depending on the platform you are using. The date and time of the query are displayed, along with the data refresh information and a message indicating that there are no warning conditions.

An "NA" in the table means that no values were returned. In some cases it is because the equipment is not supported for that environmental parameter (for example, the power supply and blowers in slots 24, 26, 28, and 29 do not have a 3V power supply, so an NA is displayed).

Command History
Usage Guidelines
The command history feature provides a record of EXEC commands you have entered. The number of commands that the history buffer will record is determined by the history size line configuration command or the terminal history size EXEC command.
Table 70 lists the keys and functions you can use to recall commands from the command history buffer.
Table 70 History Keys
Ctrl-P or Up Arrow1
Recalls commands in the history buffer in a backward sequence, beginning with the most recent command. Repeat the key sequence to recall successively older commands.
Ctrl-N or Down Arrow1
Returns to more recent commands in the history buffer after recalling commands with Ctrl-P or the Up Arrow. Repeat the key sequence to recall successively more recent commands.
1 The arrow keys function only with ANSI-compatible terminals.
Examples
The following is sample output from the show history command, which lists the commands the user has entered in EXEC mode for this session:
