Creating a Port Channel
You can create up to 128 port channels with eight port members per group on the Z9000 S4810 S4820T.
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
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 Gigabit Ethernet and 10/100/1000 Ethernet interfaces,
but FTOS 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 S4810 S4820T supports jumbo frames by default (the default maximum transmission
unit (MTU) is 1554 bytes). 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.
