Commands
You use the command line interface (CLI) from a local console or remotely using a Telnet or Secure Shell
SSH session. The CLI provides a command structure similar to Cisco NX-OS software, with
context-sensitive help, show commands, multi-user support, and role-based access control.
Each feature has show commands that provide information about the feature configuration, status, and
performance. Additionally, you can use the following commands for more information:
• show system—Provides information on system-level components, including cores, errors, and
exceptions. Use the show system error-id command to find details on error codes:

Ping
The ping utility generates a series of echo packets to a destination across a TCP/IP internetwork. When
the echo packets arrive at the destination, they are rerouted and sent back to the source. Using ping, you
can verify connectivity and latency to a particular destination across an IP-routed network.
