Configuration Procedure
The following only lists the configuration for Switch A; configure Switch B
similarly.
1 Manual link aggregation
a Create manual aggregation group 1.
[4500]link-aggregation group 1 mode manual
b Add Ethernet ports Ethernet1/0/1 to Ethernet1/0/3 into aggregation group 1.
[4500]interface ethernet1/0/1
[4500-Ethernet1/0/1]port link-aggregation group 1
[4500-Ethernet1/0/1]interface ethernet1/0/2
[4500-Ethernet1/0/2]port link-aggregation group 1
[4500-Ethernet1/0/2]interface ethernet1/0/3
[4500-Ethernet1/0/3]port link-aggregation group 1
2 Static LACP aggregation
a Create static LACP aggregation group 1.
[4500]link-aggregation group 1 mode static
b Add Ethernet ports Ethernet1/0/1 to Ethernet1/0/3 into aggregation group 1.
[4500]interface ethernet1/0/1
[4500-Ethernet1/0/1]port link-aggregation group 1
[4500-Ethernet1/0/1]interface ethernet1/0/2
[4500-Ethernet1/0/2]port link-aggregation group 1
[4500-Ethernet1/0/2]interface ethernet1/0/3
[4500-Ethernet1/0/3]port link-aggregation group 1
3 Dynamic LACP aggregation
a Enable LACP at Ethernet ports Ethernet1/0/1 to Ethernet1/0/3.
[4500]interface ethernet1/0/1
[4500-Ethernet1/0/1]lacp enable
[4500-Ethernet1/0/1]interface ethernet1/0/2
[4500-Ethernet1/0/2]lacp enable
[4500-Ethernet1/0/2]interface ethernet1/0/3
[4500-Ethernet1/0/3]lacp enable
Only when the three ports are configured with identical basic configuration, rate
and duplex mode, can they be added into a same dynamic aggregation group
after LACP is enabled on them, for load sharing.
Switch A
Switch B
