–To view a complete list of the available configuration commands, enter ? at the prompt
Example: Router(config-if)# ?
–To view a complete list of command keyword options, enter ? at the end of the command
Example: Router# service-module integrated-service-engine ?
•The commands are grouped in the tables by the configuration mode in which they are available. If the same command is available in more than one mode, it can act differently in each mode.
Shutting Down and Starting Up the Cisco Integrated Storage System Application
To start up or shut down the network module or the Cisco Integrated Storage System application that runs on the module, use the shutdown and startup commands as needed from Table 1.
Note•Some shutdown commands can potentially disrupt service. If command output for such a command displays a confirmation prompt, confirm by pressing Enter or cancel by typing n and pressing Enter. Alternatively, prevent the prompt from displaying by using the no-confirm keyword.
•Some commands shut down the module or application and then immediately restart it.
Table 1 Common Shutdown and Startup Commands
|
|
|
|
|
|
service-module integrated-service-engine slot/0 reload |
Shuts down the module operating system gracefully, and then restarts it from the boot loader. |
|
|
service-module integrated-service-engine slot/0 reset |
Resets the hardware on a module. Use only to recover from shutdown or a failed state.
Caution
Use this command with caution. It does
not provide an orderly software shutdown, and it can affect file operations that are in progress.

|
|
reload |
Shuts down the module gracefully, and then reboots the module from the boot loader. |
|
|
shutdown |
Shuts down the module application gracefully, and then shuts down the module (see caution under "Network Module Prerequisites" section on page 4) |
Verifying System Status
To verify the status of an installation, upgrade, or downgrade, or to troubleshoot problems, use verification and troubleshooting commands as needed from Table 2.
Note Among keyword options for many show commands is the provision to display diagnostic output on your screen or to "pipe" it to a file or a URL (that is, to read the output from one command and write it to the file or URL).

Diagnostics and Logging Options
Cisco Integrated Storage System diagnostics are of two types:
•System log (syslog)—Syslog is an industry-standard protocol for capturing the following events:
–Fatal exceptions that cause an application or system crash, during which normal error-handling paths are typically nonfunctional
–Application run-time errors that cause unusual conditions and configuration changes
The syslog file size is fixed at 10 MB. Syslog configurations survive a power failure.
•Traces—Trace logs capture events related to the progress of a request through the system.
Trace logs survive a CPU reset; trace configurations survive a power failure. Log and display these configurations with the trace commands.
Note Among the keyword options for many log and trace commands is the provision to display diagnostic output on your screen or to save it to a file or a URL.
Use the show errors command to display error statistics by module, entity, or activity.
SNMP Commands
Table 3 lists and describes the snmp-server SNMP command-line interface commands.
Table 3 SNMP Commands

|
|
|
snmp-server community community-string [RO | RW] no snmp-server community community-string [RO | RW] Example: iss-module(config)# snmp-server community cisco-snmp RO |
Enables the SNMP agent with the configured case sensitive community string. The password and the mode of access can be set to read-only or read-write. Up to five community strings that can be set for each read-only or read-write category. community-string—case sensitive character string with a maximum length of 15 characters. RO—Read-Only access mode. RW—Read-Write access mode. Use the no form of this command to remove the configuration associated with the community string. Note Even after all community string configurations are removed, you can still have read-only access of MIB variables using the default community strings. The default read-only community string is cisco-snmp. |

|
|
snmp-server enable traps no snmp-server enable traps Example: iss-module(config)# snmp-server enable traps |
Enables SNMP traps to be sent to the SNMP trap destination. Note This command is effective only for certain types of notifications. Not all types of notifications are controlled by this command. Also, this CLI does not control the traps generated from exceeding the system resource thresholds. The only form of notifications enabled (or disabled) by this CLI are the traps generated from syslog messages with severity level greater than or equal to that of warning level. Use the no form of this command to disable trap notifications to be sent to the trap destination. |
|
|
snmp-server host ip-address community-string no snmp-server host ip-address community-string Example: iss-module(config)# snmp-server host 1.100.10.219 cisco-snmp |
Configures the IP address of the host that is to receive the trap notifications. The community string must also be specified. Up to a maximum of 5 hosts that can be configured. Note The snmp-server enable traps command must be executed for the hosts to receive the trap notifications. ip-address—IP address (IPv4 only is supported) in dotted decimal notation of the host that is to receive the trap notifications. community-string—character string with a maximum length of 15 characters. Use the no form of this command to clear the host configuration. |
|
|
snmp-server location location-name no snmp-server location location-name Example: iss-module(config)# snmp-server contact "San Jose" |
Sets or clears the location name. location-name—character string with a maximum length of 31 characters. Use the no form of this command to clear the location name. |

Sets the threshold for monitoring the disk usage for all the disks, including local, NFS, and iSCSI devices. percentage—Integer variable in the range of 1 to 30 that represents the percentage of free space within each disk partition. If the free disk space percentage falls below this threshold, the system will generate a trap. Use the no form of this command to disable disk monitoring. |
|
|
snmp-server monitor cpu percentage no snmp-server monitor cpu percentage Example: iss-module(config)# snmp-server monitor cpu 10 |
Sets the threshold for monitoring the CPU utilization. percentage—Number in the range of 0 to 20 that represents the percentage of idle CPU time. This number includes wait states. Use the no form of this command to disable CPU monitoring |
