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 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 10/100/1000 Mbps Interfaces in Port Channels ).
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 system 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.
To add a physical interface to a port, use the following commands.
1 Add the interface to a port channel.
INTERFACE PORT-CHANNEL mode
channel-member interface
The
interface
variable is the physical interface type and slot/port information.
2 Double check that the interface was added to the port channel.
INTERFACE PORT-CHANNEL mode
show config
Examples of the
show interfaces port-channel
Commands
To view the port channel’s status and channel members in a tabular format, use the
show interfaces port-channel brief
command in EXEC Privilege mode, as shown in the following example.
