Display And Debug Link Aggregation - 3Com 7700 Configuration Manual

Display and Debug Link
Aggregation
Example: Configuring
Link Aggregation
Perform the following configuration in system view.
Table 14 Aggregating Ethernet Ports
Operation
Aggregate Ethernet ports
Remove a configured link
aggregation
Note: The Ethernet ports to be aggregated should be configured with the same
speed and duplex otherwise, they cannot be aggregated. The Switch 7700 does
not support ingress aggregation mode.
After the previous configuration, execute the display command in all views to
display the running of the link aggregation configuration, and to verify the effect
of the configuration.

Operation

link aggregation
The following example uses the link aggregation commands to aggregate several
ports and implements the outgoing/incoming payload balance among all the
member ports. The link aggregation is typically used for Trunk ports. Since the
Trunk port allows frames from several VLANs to pass through, the heavy traffic
needs balancing among all the ports.
Ethernet Switch (Switch A) is connected to the Ethernet Switch (Switch B)
upstream via the aggregation of three ports, Ethernet1/0/1 through Ethernet1/0/3.
