interface 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 channelin Layer 2 mode or configure an IP address to place the port channel in Layer 3 mode, use theswitchport command.You can configure a port channel as you would a physical interface by enabling or configuring protocolsor assigning access control lists.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 samephysical 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 channelmember 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 canconfigure 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 thephysical interfaces if they are part of a port channel.NOTE: The Z9000 supports jumbo frames by default (the default maximum transmission unit (MTU)is 12000 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 showconfig command or from EXEC Privilege mode, use the show running-config interfaceinterface 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 interfaceThe 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 modeshow configInterfaces 329
