Monitoring Temperature

The Cisco Catalyst Blade Switch 3020 for HP monitors the switch temperature conditions.

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 switch (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.

Using Ping

Understanding Ping

The switch supports IP ping, which you can use to test connectivity to remote hosts. Ping sends an echo

request packet to an address and waits for a reply. Ping returns one of these responses:

• Normal response—The normal response (hostname is alive) occurs in 1 to 10 seconds, depending

on network traffic.

• Destination does not respond—If the host does not respond, a no-answer message is returned.

• Unknown host—If the host does not exist, an unknown host message is returned.

• Destination unreachable—If the default gateway cannot reach the specified network, a

destination-unreachable message is returned.

• Network or host unreachable—If there is no entry in the route table for the host or network, a

network or host unreachable message is returned.

Executing Ping

Beginning in privileged EXEC mode, use this command to ping another device on the network from the

switch:

Note Though other protocol keywords are available with the ping command, they are not supported in this

release.

Command Purpose
