Configuring a PE Stack
Before you start, ensure that the PE stack units are cabled in a ring topology, powered on, and that one or
more stack units are attached to a 10GbE port on the parent C9010. For detailed information, see the Dell
Networking C1048P Getting Started Guide
or Dell Networking C1048P Installation Guide.
From a console attached to the C9010 or through a Telnet session to the C9010 management port:
1. Turn on support for the port-extender configuration on a C9010.
CONFIGURATION mode
feature extended-bridge
2. Enter Port-Extender Configuration mode to provision a PE stack by using the PE ID. A Cascade LAG
(port channel) is automatically created, once PE is provisioned or created.
CONFIGURATION mode
pe provision pe-id
• pe-id is a port-extender ID number from 0 to 255.
3. Configure the cascade ports on the C9010 which are attached to PE stack units. The cascade ports
must be operationally up (the no shutdown command) and have a default port configuration with
no L2 and L3 configuration. The port interfaces must be the same type. You can configure up to
sixteen C9010 ports in the auto-LAG. The generated auto-LAG number is from 258 to 513.
PORT-EXTENDER CONFIGURATION mode
Dell(conf-pe-0)# cascade interface interface-type slot/port-range
• interface interface-type specifies a C9010 10-Gigabit Ethernet interface. The only
supported value is
TenGigabitEthernet slot/port-range.
• slot/port-range specifies a C9010 10GbE port, including slot number and either a single port
number, a port range, or a combination of both for auto-LAG configuration.
• The range of slot numbers is from 0 to 9 for linecard slots. The range of port numbers is from 0
to 23.
• Enter a port range with or without spaces; for example, cascade interface
tengigabitethernet 0/1-5
or cascade interface tengigabitethernet 0/1 - 5.
• You can enter up to six comma-separated ranges or port numbers; for example, cascade
interface tengigabitethernet 0/1-2,8,10–12,15.
4. Enable the C9010 cascade ports.
CONFIGURATION mode
interface tengigabitethernet slot/port-range
INTERFACE CONFIGURATION mode
no shutdown
Example of Configuring a PE Stack
NOTE: Dell Networking OS recommends not to use RPM Slots 10 and 11 for PE connectivity.
Dell(conf)# feature extended-bridge
Dell(conf)# pe provision 2
Dell(conf-pe-2)# cascade interface tengigabitethernet 0/0-1
Dell(conf-pe-2)# exit
Dell(conf)# interface range tengigabitethernet 0/0-1
