Use the Port Channel Configuration page to group one or more full duplex Ethernet links to be aggregated together to form a port channel, which is also known as a LAG (Link Aggregation Group). The switch treats the port channel as if it were a single link.
To access this page, click in the navigation menu. Select a port and click Edit.
Port Channel Configuration Fields
| Field | Description |
|---|---|
| Port Channel Interface | Select the port channel to configure. The port channel follows a Slot/Port (or Unit/Slot/Port for stacking platforms) interface naming convention, where the slot is 3. |
| Port Channel Name | Enter the name you want assigned to the Port Channel. You may enter any string of up to 15 alphanumeric characters. You must specify a valid name in order to create the Port Channel. |
| Link Trap | Specify whether you want to have a trap sent when link status changes. The factory default is enable, which will cause the trap to be sent. |
| Administrative Mode | Select enable or disable from the drop-down menu. When the Port Channel is disabled no traffic will flow and LACPDUs will be dropped, but the links that form the Port Channel will not be released. The factory default is enable. |
| Link Status | Whether the link is Up or Down. |
| STP Mode | Select the STP Administrative Mode associated with the
Port Channel:
|
| Static Mode | Select enable or disable from the drop-down menu. The factory default is Disable.
|
| Local Preference Mode | This field is available only on systems that support stacking. When this option is enabled, the LAG-destined unicast traffic egresses only out of members of the LAG interface on the local unit. This feature makes sure that the LAG-destined unicast traffic does not cross the external stack link when the LAG has members on the local unit. |
| Load Balance | Select the hashing algorithm used to distribute the traffic load among available physical ports in the LAG. The range of possible values may vary with the type of switch. The possible values are:
|
| Port Channel Members | After you create one or more port channel, this field lists the members of the Port Channel. If there are no port channels on the system, this field is not present. |
| Unit/Slot/Port | This column lists the physical ports available on the system. |
| Participation | Select each port‘s membership status for the Port Channel you are configuring. There can be a maximum of 8 ports assigned to a Port Channel.
|
| Membership Conflicts | Shows ports that are already members of other Port Channels. A port may only be a member of one Port Channel at a time. If the entry is blank, the port is not currently a member of any Port Channel |
