Install Guide

As soon as a physical interface is added to a port channel, the properties of the port channel determine the properties of the
physical interface. The configuration and status of the port channel are also applied to the physical interfaces within the port
channel. For example, if the port channel is in Layer 2 mode, you cannot add an IP address or a static MAC address to an
interface that is part of that port channel. In the following example, interface 1/6 is part of port channel 5, which is in Layer 2
mode, and an error message appeared when an IP address was configured.
Reassigning an Interface to a New Port Channel
An interface can be a member of only one port channel. If the interface is a member of a port channel, remove it from the first
port channel and then add it to the second port channel.
Each time you add or remove a channel member from a port channel, Dell EMC Networking OS recalculates the hash algorithm
for the port channel.
To reassign an interface to a new port channel, use the following commands.
1. Remove the interface from the first port channel.
INTERFACE PORT-CHANNEL mode
no channel-member interface
2. Change to the second port channel INTERFACE mode.
INTERFACE PORT-CHANNEL mode
interface port-channel id number
3. Add the interface to the second port channel.
INTERFACE PORT-CHANNEL mode
channel-member interface
The following example shows moving an interface from port channel 4 to port channel 3.
Configuring the Minimum Oper Up Links in a Port Channel
You can configure the minimum links in a port channel (LAG) that must be in “oper up” status to consider the port channel to be
in “oper up” status.
To set the “oper up” status of your links, use the following command.
● Enter the number of links in a LAG that must be in “oper up” status.
INTERFACE mode
minimum-links number
The default is 1.
Example of Configuring the Minimum Oper Up Links in a Port Channel
DellEMC#config t
DellEMC(conf)#int po 1
DellEMC(conf-if-po-1)#minimum-links 5
DellEMC(conf-if-po-1)#
Adding or Removing a Port Channel from a VLAN
As with other interfaces, you can add Layer 2 port channel interfaces to VLANs. To add a port channel to a VLAN, place the
port channel in Layer 2 mode (by using the switchport command).
To add or remove a VLAN port channel and to view VLAN port channel members, use the following commands.
● Add the port channel to the VLAN as a tagged interface.
INTERFACE VLAN mode
tagged port-channel id number
An interface with tagging enabled can belong to multiple VLANs.
● Add the port channel to the VLAN as an untagged interface.
