An Eth-Trunk load balances incoming and outgoing traffic
among multiple links and improves the bandwidth and connection reliability
between two switches.
Context
You can configure Eth-Trunks in the following scenarios:
- The bandwidth is insufficient when two switches are connected through
only one link.
- The connection reliability cannot meet requirement when two switches are connected through
only one link.
Procedure
- Query Eth-Trunk information.
- Choose in the navigation tree, and the Eth-Trunkport page is displayed.
- Enter the interface name, for example, 12.
- Click Query to display all matching
records.
- Create an Eth-Trunk.
- Choose in the navigation tree, and the Eth-Trunkport page is displayed.
- Click New, and the Create Eth-Trunk page is displayed.
Table 1 describes the parameters on the Create Eth-Trunk page.
Table 1 Create Eth-Trunk
Parameter
|
Description
|
Eth-Trunk Name
|
Indicates the name of an Eth-Trunk. This parameter
is mandatory.
|
BPDU
|
Indicates whether to enable BPDU. The options are Enable and Disable. By default, BPDU
is disabled.
|
Working Mode
|
Indicates the working mode of the Eth-Trunk, including: - Manual load balancing mode
When the bandwidth or the reliability
between two devices needs to be increased and one device does not
support LACP, you should create an Eth-Trunk in manual load balancing
mode and add member interfaces to the Eth-Trunk.
- Static LACP mode
The links between two devices can implement
redundancy backup. When a fault occurs on some links, the backup links
replace the faulty ones to keep data transmission uninterrupted.
The default mode is manual load balancing. NOTE: - Check whether the Eth-Trunk contains member interfaces before
you set the working mode of the Eth-Trunk. If the Eth-Trunk contains
member interfaces, the working mode of the Eth-Trunk cannot be changed.
- The working modes on the local end and remote end must be the
same.
|
Min Active Links
|
Indicates the lower threshold of the number of active interfaces.
You can specify the lower threshold of active interfaces in the Eth-Trunk.
If the number of active interfaces is smaller than this value, the
status of the Eth-Trunk becomes Down. NOTE: - The lower threshold must be not greater than the upper threshold.
- The lower thresholds of active member interfaces can be set to
different values for the local end and remote end. If the lower thresholds
at the two ends are different, the greater one is used.
|
Max Active Links
|
Indicates the upper threshold of the number of active interfaces. NOTE: - The lower threshold must be not greater than the upper threshold.
- The upper thresholds of active member interfaces can be set to
different values for the local end and remote end. If the upper thresholds
at the two ends are different, the smaller one is used.
- In manual load balancing mode, this parameter has a fixed value
8.
|
LACP Timeout
|
Indicates the timeout period for receiving LACP packets
on an interface in static LACP mode: This parameter is valid only
when the static LACP mode is enabled. The timeout can be set to 3
seconds for fast mode or 90 seconds for slow mode.
|
LACP preempt Delay
|
Indicates whether to enable the preempt delay function in
static LACP mode. By default, the preempt delay function is enabled.
This parameter is valid only when the static LACP mode is enabled.
|
Preempt Delay
|
Specifies the delay for LACP priority preemption. This parameter
is valid only when the static LACP mode and preempt delay functions
are enabled.
|
Load Balancing Mode
|
Indicates the load balancing mode of Eth-Trunk, including: - Destination IP
- Destination MAC
- Source IP
- Exclusive-or of source and destination IP
- Source MAC
- Exclusive-or of source and destination MAC
By default, load balancing is based on the "Exclusive-OR"
result of the source and destination IP addresses.
|
Link Type
|
Indicates the link type of an interface. The value cannot
be changed.
|
Jumbo
|
Indicates the length of a Jumbo frame. This parameter is
optional.
|
Description
|
Indicates the description of the created Eth-Trunk.
|
Select Interface
|
Adds member interfaces to the Eth-Trunk.
An Eth-Trunk
contains a maximum of eight member interfaces. NOTE: - Member interfaces of an Eth-Trunk must have the same interface
type.
- A member interface cannot be an Eth-Trunk.
|
- Set parameters.
When selecting the interface:
- If this interface is configured by other Eth-Trunks, it is unavailable
and cannot be selected.
- If this interface is not configured, you can select it.
- If this interface does not join the Eth-Trunk and is configured
by other modules except shutdown and combo, the Configure Basic Attributes page is displayed. You can clear the
original configurations of this interface.
- Click OK.
- Modify Eth-Trunk
- Choose in the navigation tree to open the Eth-Trunkport page.
- Select a record that you want to modify and click
to open the Modify Eth-Trunk page.
Table 1 describes the parameters on the Modify Eth-Trunk page.
NOTE: - The Eth-Trunk name cannot be modified.
- Before changing the working mode of an Eth-Trunk, ensure that
the Eth-Trunk does not contain any member interfaces.
- Set parameters.
When selecting the interface:
- If this interface is configured by other Eth-Trunks, it is unavailable
and cannot be selected.
- If this interface is not configured, you can select it.
- If this interface does not join the Eth-Trunk and is configured
by other modules except shutdown and combo, the Configure Basic Attributes page is displayed. You can clear the
original configurations of this interface.
- Click OK.
- Delete Eth-Trunks.
- Choose in the navigation tree to open the Eth-Trunkport page.
- Select a record that you want to delete and click Delete. The system asks you whether to delete the record.
- Click OK.
NOTE: An Eth-Trunk cannot be deleted when it
has member interfaces.
