NOTE
Do not connect stacking ports to non-stacking ports. Stacking ports have a proprietary packet
format that renders them incompatible with regular ports even when they are forwarding regular
packets. In linear topologies, make sure that end units have only one stacking port configured
(secure-setup automatically configures only one stacking port for an end unit).
Configuring a single stack port
NOTE
The two left ports on the Four-port 10 Gpbs SFP+ module do not pass regular Ethernet traffic by
default. The stack disable must be entered at the global level and the long preamble command must
be configured on these two ports in order for them to pass regular traffic. Use show stack stack-port
command to confirm port mode.
To configure a single stack port, enter a command similar to the following.
PowerConnect(config)# stack unit 3
PowerConnect(config-unit-3)# stack-port 3/2/1
Syntax: [no] stack-port <stack-unit/slotnum/portnum>
