Monitoring SFP Module Status You can check the physical or operational status of an SFP module by using the show interfaces transceiver privileged EXEC command. This command shows the operational status, such as the temperature and the current for an SFP module on a specific interface and the alarm status. You can also use the command to check the speed and the duplex settings on an SFP module. For more information, see the show interfaces transceiver command in the command reference for this release. Executing Ping If you attempt to ping a host in a different IP subnetwork, you must define a static route to the network or have IP routing configured to route between those subnets.
IP routing is disabled by default on all devices. Though other protocol keywords are available with the ping command, they are not supported in this release. Note Use this command to ping another device on the network from the device: Monitoring Temperature The Device monitors the temperature conditions and uses the temperature information to control the fans. Use the show env temperature status privileged EXEC command to display the temperature value, state, and thresholds.
The temperature value is the temperature in the Device(not the external temperature).You can configure only the yellow threshold level (in Celsius) by using the system env temperature threshold yellow value global configuration command to set the difference between the yellow and red thresholds. You cannot configure the green or red thresholds. For more information, see the command reference for this release. Monitoring the Physical Path You can monitor the physical path that a packet takes from a source device to a destination device by using one of these privileged EXEC commands: Table 1:
