Stacking
All commands in this chapter are specific to the Dell EMC Networking OS.
You can use the commands to pre-configure a switch, so that the configuration settings are invoked when the switch is attached to other
S-Series units.
For information about using the S-Series stacking feature, see the Stacking S-Series Switches section in the Dell EMC Networking OS
Configuration Guide.
CAUTION: You cannot enable stacking simultaneously with virtual link trunking (VLT). If you enable both at the same
time, unexpected behavior occurs.
The Dell EMC Networking OS commands for data center bridging features include 802.1Qbb priority-based flow control (PFC), 802.1Qaz
enhanced transmission selection (ETS), and the data center bridging exchange (DCBX) protocol.
