Viewing Command History

The command-history trace feature captures all commands entered by all users of the system with a time stamp and writes these

messages to a dedicated trace log buer.

The system generates a trace message for each executed command. No password information is saved to the le.

To view the command-history trace, use the show command-history command.

Example of the show command-history Command

Dell#show command-history

Upgrading the Dell Networking OS

To upgrade the Dell Networking operating system on the switch, refer to the Release Notes for the software version you want to load.

NOTE: If VLT is already congured in a device loaded with Dell Networking OS version 9.9(0.0), you must rst remove the VLT

conguration to upgrade to the Dell Networking OS version 9.10(0.0) or later. After removing the VLT conguration, upgrade

each VLT node and its corresponding single-homed PE individually and then reload both nodes as well as PEs. After the CBs and

PEs come up with Dell Networking OS version 9.10(0.0) or later, congure VLT again. When you congure VLT, the PEs rst go

down and then come up.
