• Deleting or Disabling a Port Channel (optional)• Load Balancing Through Port Channels (optional)Creating a Port ChannelYou 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 modeinterface port-channel id-number2. Ensure that the port channel is active.INTERFACE PORT-CHANNEL modeno shutdownAfter 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 orconfigure 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 controllists.Adding a Physical Interface to a Port ChannelThe 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 NetworkingOS disables the interfaces that are not the same speed of the first channel member in the port channel (refer to10/100/1000 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 followingcommands 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 partof a port channel.NOTE: The Z9000 supports jumbo frames by default (the default maximum transmission unit (MTU) is 12000 bytes). Toconfigure 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 fromEXEC 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 modechannel-member interface288 Interfaces
