Creating A Port Channel; Adding A Physical Interface To A Port Channel - Dell C9000 Series Networking Configuration Manual

Creating a Port Channel

You can create up to 128 port channels with 16 port members per group on the switch.
To configure a port channel, use the following commands.
1 Create a port channel.
CONFIGURATION mode
interface port-channel id-number
2 Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
After you enable the port channel, you can place it in Layer 2 or Layer 3 mode. To place the port channel in
Layer 2 mode use the switchport command, or configure and IP address to place the port channel in Layer
3 mode.
NOTE: L3 is not supported on port extender (PE) ports or on port-channels when they have PE ports as
members.
You can configure a port channel as you would a physical interface by enabling or configuring protocols or
assigning access control lists.

Adding a Physical Interface to a Port Channel

The physical interfaces in a port channel can be on any line card in the chassis, but must be the same physical
type.
You can add any physical interface to a port channel if the interface configuration is minimal. You can
configure only the following commands on an interface if it is a member of a port channel:
•
description
•
shutdown/no shutdown
•
mtu
• ip mtu (if the interface is on a Jumbo-enabled by default)
NOTE: A logical port channel interface cannot have flow control. Flow control can only be present on the
physical interfaces if they are part of a port channel.
NOTE: The switch supports jumbo frames by default (the default maximum transmission unit (MTU) is
9216 bytes). To configure the MTU, use the mtu command from INTERFACE mode.
To view the interface's configuration, enter INTERFACE mode for that interface and use the show config
command or from EXEC Privilege mode, use the show running-config interface interface
command.
When an interface is added to a port channel, the system recalculates the hash algorithm.
