Creating a Port Channel
You can create up to 128 port channels with four port members per group on the Aggregator.
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 3 mode. To configure an IP address to place the
port channel in Layer 3 mode, use the switchport command.
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.
NOTE
: Port channels can contain a mix of Gigabit Ethernet and 10/100/1000 Ethernet interfaces, but Dell
Networking OS disables the interfaces that are not the same speed of the first channel member in the
port channel.
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.
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, Dell Networking OS recalculates the hash algorithm.
