Displaying and
Maintaining Link
Aggregation
Configuration
After the above configuration, execute the display command in any view to
display the running status after the link aggregation configuration and verify your
configuration.
Execute the reset command in user view to clear LACP statistics on ports.
Link Aggregation
Configuration
Example
Network requirements
■ Switch A connects to Switch B with three ports Ethernet1/0/1 to Ethernet1/0/3.
It is required that incoming/outgoing load between the two switch can be
shared among the three ports.
■ Adopt three different aggregation modes to implement link aggregation on the
three ports between switch A and B.

Configure parameters used by
the HASH algorithm in link
aggregation
hash { dstip | dstmac | ip |
l4port | mac | srcip | srcmac }
{ ioboard slot slot-number |
mainboard }
By default, Type A I/O
Modules use four-tuple
(dstip, dstmac, srcip and
srcmac) as the parameter of
HASH algorithm. I/O Modules
other than Type A use ip as
the parameter of HASH
algorithm.
