Configuration Restrictions And Guidelines; Configuring A Layer 2 Aggregation Group - H3C S5560S-EI Series Configuration Manual

Configuration restrictions and guidelines

The following information describes restrictions and guidelines that you must follow when you
configure link aggregations.
Aggregation member interface restrictions
•
You cannot assign an interface to a Layer 2 aggregation group if any features in
configured on that interface.
Table 4 Features incompatible with Layer 2 aggregation member interfaces
Feature on the interface
MAC authentication
Port security
802.1X
•
Do not assign a reflector port for port mirroring to an aggregation group. For more information
about reflector ports, see Network Management and Monitoring Configuration Guide.
Configuration consistency requirements
•
You must configure the same aggregation mode at the two ends of an aggregate link.
•
For a successful static aggregation, make sure the ports at both ends of each link are in the
same aggregation state.
•
For a successful dynamic aggregation, make sure the peer ports of the ports aggregated at one
end are also aggregated. The two ends can automatically negotiate the aggregation state of
each member port.
Miscellaneous
Deleting an aggregate interface also deletes its aggregation group and causes all member ports to
leave the aggregation group.

Configuring a Layer 2 aggregation group

Configuring a Layer 2 static aggregation group
Step
1.
Enter system view.
2.
Create a Layer 2 aggregate
interface and enter Layer 2
aggregate interface view.
3.
Exit to system view.
4.
Assign an interface to the
specified Layer 2
aggregation group.

quit
a
Enter Layer 2 Ethernet
interface view:

b
Assign the interface to the
specified Layer 2
aggregation group:

Remarks
N/A
When you create a Layer 2
aggregate interface, the system
automatically creates a Layer 2
static aggregation group
numbered the same.
N/A
Repeat these two substeps to
assign more Layer 2 Ethernet
interfaces to the aggregation
group.
