stack-unit portmode quad
Configures the list of dynamic fan-out capable ports.
Syntax
stack-unit [stack-unit number] port port-number portmode quad
To remove the quad-port configuration, use the [no] stack-unit[stack-unit number] port
port-number portmode quad command.
Parameters
stack-unit
number
Enter the port number. The range is from 0 to 5.
Defaults 0,8,16,24,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,100,108,116,124

9.7(0.0) Introduced on the S6000 and S6000–ON.
Usage
Information
The default quad port profile configuration includes all ports except the top four left ports and the
top four right ports in the switch. As a result, you cannot fan-out these switch ports using the stack-
unit stack-unit-number portmode command when the ports are in the default quad port profile
configuration.
You can change this default quad port profile configuration using the stack-unit stack-unit-
number port port-numbers portmode quad command and include the top four left ports and
top four right ports in your new profile. When you change the default profile, you can dynamically fan-out
the ports that are part of the new profile using the stack-unit stack-unit-number portmode
quad command.
However, your new profile must exclude four ports from the first 16 port groups and four ports from the
last 16 port groups in the switch. You cannot fan-out these excluded ports as the quad port profile can
only have 12 ports in the first 16 port groups and 12 ports in the last 16 port groups.
For the new quad port profile configuration to take effect, you must first save changes and then reload
the switch.
Example
Dell(conf)# stack-unit 1 slot 3 port 15 portmode quad speed 10G
Warning: Enabling Quad mode on stack-unit 1 slot 3 port 15. Please
verify whether the configs related to interface Fo 1/3/15 Fo 1/3/16 are
cleaned up before proceeding further.
[confirm yes/no]:y
Quad mode is enabled on stack-unit 1 slot 3 port 15
The interface on stack-unit 1 slot 3 port 16 has been removed
%STKUNIT1-M:CP %IFMGR-5-DYNAMIC_FANOUT: Port 15 in slot 3 has been

show interfaces switchport
Display only virtual and physical interfaces in Layer 2 mode. This command displays the Layer 2 mode interfaces’ IEEE 802.1Q
tag status and VLAN membership.
Syntax
show interfaces switchport [interface-type | stack-unit unit-id ]
Parameters
interface-type (OPTIONAL) Enter one of the following keywords and the interface information:
● For a port channel interface, enter the keywords port-channel then a
number.
