Conguration Tasks for Port Channel Interfaces
To congure a port channel (LAG), use the commands similar to those found in physical interfaces. By default, no port channels are
congured in the startup conguration.
These are the mandatory and optional conguration tasks:
• Creating a Port Channel (mandatory)
• Adding a Physical Interface to a Port Channel (mandatory)
• Reassigning an Interface to a New Port Channel (optional)
• Conguring the Minimum Oper Up Links in a Port Channel (optional)
• Adding or Removing a Port Channel from a VLAN (optional)
• Assigning an IP Address to a Port Channel (optional)
• Deleting or Disabling a Port Channel (optional)
Creating a Port Channel
You can create up to 128 port channels with 16 port members per group on a switch.
To congure 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 congure an IP
address to place the port channel in Layer 3 mode, use the switchport command.
You can congure a port channel as you would a physical interface by enabling or conguring 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 conguration 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 rst channel member in the port channel (refer to
100/1000/10000 Mbps Interfaces in Port Channels).
You can congure 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
congure the MTU using the mtu command from INTERFACE mode.
