Creating A Port Channel; Adding A Physical Interface To A Port Channel - Dell S4820T Configuration Manual

Creating a Port Channel

You can create up to 512 port channels with up to 16 port members per group on the platform.
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 or 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 (refer to
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 S4820T supports jumbo frames by default (the default maximum transmission unit
(MTU) is 1554 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, Dell Networking OS recalculates the hash algorithm.
