Table 88 Creating/deleting an aggregation group
Operation
Create an aggregation group
Delete an aggregation group
During creating an aggregation group, if it already exists in the system but
contains no member port, it changes to the new type. When you change a static
LACP aggregation group to a manual one, LACP shall be disabled at the member
ports automatically.
Port aggregation includes manual aggregation, static aggregation and dynamic
aggregation.
In the manual aggregation mode, ports working at different rates can be
■
aggregated. Manual aggregation can be load balancing aggregation if the
aggregation resource is available. In this case, if the traffic rate shared by a
low-rate port exceeds the maximum rate of the port, packets may be lost.
In the static aggregation mode, ports working at different rates can also be
■
aggregated. However, the selected/standby state of statically aggregated ports
is determined by the transmission rate. Only the ports with the maximum rate
and in full-duplex mode can be selected to forward traffic, while other standby
ports do not forward traffic.
You can add/delete ports into/from an aggregation group.
Perform the following configuration in the corresponding view.
Table 89 Adding/deleting an Ethernet port into/from an aggregation group
Operation
Add an Ethernet port into the aggregation
group (Ethernet port view)
Delete an Ethernet port from the aggregation
port (Ethernet port view)
Aggregate Ethernet ports (system view)
Note that:
You cannot add a mirrored port, a port configured with a static MAC address, a
■
port with 802.1x enabled, or a VPN port into an aggregation group.
You must delete the aggregation group, instead of the port, if the aggregation
■
group contains only one port.
When master port enables VLAN VPN, aggregation is permitted in the system.
■
Because the link type of slave port will always keep same as that of master
port. When both master port and slave have VLAN VPN disabled, aggregation
is permitted in the system, it is average aggregation. After the port enabling
VLAN VPN, aggregation is not permitted in the system, at the same time, the
system will tell users that the slave port in the aggregation group conflict with
the master port on VLAN VPN.
