Stacking
All commands in this chapter are specic to the Dell Networking operating software.
You can use the commands to pre-congure a switch, so that the conguration settings are invoked when the switch is attached to
other S-Series units.
For information about using the S-Series stacking feature, refer to the “Stacking S-Series Switches” chapter in the Dell Networking
OS Conguration 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 Networking OS commands for data center bridging features include 802.1Qbb priority-based ow control (PFC), 802.1Qaz
enhanced transmission selection (ETS), and the data center bridging exchange (DCBX) protocol.
Switch Stacking and DCB Caveats for the S4820T
The following is a list of behaviors and limitations regarding the use of DCB over S4820T ports involved in switch stacking:
• You can enable DCB only on 40Gig (QSPF+) ports.
• DCB is not supported over any of the 48 RJ-45 10Gig ports while they are congured in Stacking mode.
• You cannot congure stacking on any of the 48 RJ-45 10Gig ports if you enable DCB on any of the 40Gig stacking ports.
• If you enable DCB, it disables the ability to use any of the 48 10Gig ports for stacking.
