Switch 7700 Configuration Guide

Link Aggregation Configuration 35
Perform the following configuration in system view.
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.
Display and Debug Link
Aggregation
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.
Example: Configuring
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.
Figure 2 Configure Link Aggregation
The following configurations are for Switch A. Configure Switch B the same way.
1 Aggregate Ethernet1/0/1 through Ethernet1/0/3.
