Command History

This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command Line Reference Guide.

The following is a list of the Dell Networking OS version history for this command.

Version
Description
9.10(0.1)
Introduced on the S4048T-ON and S4048–ON.
Usage Information
  • To form a mixed-mode stack, use only the 40G ports between the range 49 to 54.
  • You cannot form a mixed-mode stack using the 10G ports. Because, the 10G ports on the S4048T are copper ports; where as, the 10G ports on the S4048-ON are SFP ports.
  • It is mandatory to enable mixed-mode stacking on the S4048-ON and S4048T-ON switches before joining a mixed-mode stack.
  • Stack election is based on the priority or the MAC address of the stack units as in homogenous stacking. The stack-unit with the highest priority or MAC address is chosen as the master.
  • TDR is a feature that is supported only on the S4048T-ON but not on the S4048-ON. If TDR is configured on the S4048T-ON, then mixed-mode stacking can be enabled only on the S4048T-ON switches.
  • The hardware watchdog command is enabled only when the S4048T-ON act as master. As a single image runs on both the S4048T-ON as well as the S4048–ON, the hardware watchdog command is retained on the S4048-ON also. However, this command remains ineffective and does not perform any function when the S4048-ON acts as master.
  • When the S4048T-ON is the master and mixed-mode stacking is disabled, the S4048-ON remains in the card problem state due to type mismatch.
  • When the S4048-ON is the master and mixed-mode stacking is disabled, the S4048T-ON remains in the card problem state due to type mismatch.

After you issue this command. the following message appears prompting you to confirm the configuration:

Enabling mixed-mode-stacking requires configuration save and reload to operate in compatible with S4048-ON. Do you want to reload? Proceed[confirm yes/no]:

To make the S4048T-ON work like the S4048–ON, enter yes at this prompt and press the return key. The following message appears prompting you to save the configuration:

System configuration has been modified. Save? [yes/no]:

Enter yes again and press the return key.

Example (S4048T-ON)
