Creating a Port Channel
You can create up to 128 port channels with 16 port members per group on a 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 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
You can add any physical interface to a port channel if the interface configuration is minimal.
NOTE: Port channels can contain a mix of 100/1000/10000 Ethernet interfaces and 10 Gigabit Ethernet interface, but the
Dell Networking OS disables the interfaces that are not the same speed of the first channel member in the port channel
(refer to 100/1000/10000 Mbps Interfaces in Port Channels).
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:
The switch supports jumbo frames by default (the default maximum transmission unit [MTU] is 1554 bytes) You can
configure the MTU using 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.
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
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.
