Modifying the Link Aggregation for Security Devices
You can combine multiple Ethernet interfaces to form a single link layer interface, known as a Link Aggregation Group (LAG). This page enables you to create, edit, and delete LAG configuration profiles and also includes Global Settings, AE Interface, Logical Interface, Admin Status, Link status, VLAN Tagging, and so on.
Refer to the Junos OS documentation (available at http://www.juniper.net/documentation/en_US/release-independent/junos/information-products/pathway-pages/junos/product/) for a particular release and device. There you can find detailed information on the configuration parameters for that device.
To modify Link Aggregation profile:
Field |
Action |
---|---|
Global Settings |
Click to add a Global Settings to a Link Aggregation profile. The Global Settings page appears. Complete the configuration according to the guidelines provided in Table 2 and click OK. |
Add Logical Interface |
Click to add a logical interface for the security devices. You can add an Aggregated Ethernet (AE) interface followed by a logical interface to a device. The Add Logical Interface page appears. Complete the configuration according to the guidelines provided in Table 3 and click OK. |
Enable/Disable |
Click to enable or disable an existing Link Aggregation profile. |
Create an Aggregated Ethernet (AE) Interface |
Click + to add an AE Interface. The Add AE Interface page appears. Complete the configuration according to the guidelines provided in Table 4 and click OK. |
Modify an AE Interface |
Select a Link Aggregation profile and click the pencil icon. The Modify AE Interface page appears, which shows the same fields as create a SSL Initiation Profile. You can modify some of the fields on this page. See Table 4 for more details on the fields. Click OK to save the changes. |
Delete an AE Interface |
Select one or more interfaces that you want to delete, and click the bin icon to delete the profiles. The Warning page appears. Click Yes to confirm the deletion. |
Show Hide Columns |
Select to show or hide various parameters in the grid. |
Field |
Guideline |
---|---|
Device Count |
Enter the device count. This is the number of Aggregated Ethernet devices. Note:
The range is 1 through 128. |
Field |
Guidline |
---|---|
General | |
AE Interface Name |
Displays the AE Interface name that you have selected from the table. |
Logical Interface Unit |
Enter a valid logical interface. The range is 0 to 65535. Note:
By default, the value will be 0, unless VLAN tagging is enabled. You must enable VLAN tagging if you want to enter a value greater than zero. |
Description |
Enter a valid description for logical interface. The maximum limit being 255 characters. |
VLAN ID |
Enter the VLAN ID. The range is 0 to 4094. Note:
If the VLAN tagging is enabled, then the VLAN ID is mandatory. |
IPV4 Address | |
Add an IPV4 Address |
Select + to add an IPV4 address for the logical interface. |
IPV4 Address |
Enter a valid IPV4 address. |
Subnet Mask |
Enter a valid subnet mask for IPV4 address. |
IPV6 Address | |
Add an IPV6 Address |
Select + to add an IPV6 address for logical interface. |
IPV6 Address |
Enter a valid IPV6 address. |
Subnet Mask |
Enter a valid subnet mask for IPV6 address. |
Field |
Guidelines |
---|---|
Global Settings | |
AE Name |
Enter the name of the aggregated interface. If an aggregated interface already exists, then the field is displayed as read-only. |
Interfaces |
Select the interface available for aggregation and move to Selected column using right arrow. Note:
Only interfaces that are configured with the same speed can be selected together for a LAG. |
Advanced Settings | |
LACP Configuration |
Specifies global Link Aggregation Control Protocol configuration. |
LACP Mode |
Select the mode in which Link Aggregation Control Protocol packets are exchanged between the interfaces. The modes are:
|
Periodic |
Select transmission rates of link aggregation control PDUs. The options are:
|
System Priority |
Select the priority level that you associate with the LAG. Select the priority level that you want to associate with the LAG by clicking the arrow button. The range is 0 to 65535. |
Link Protection |
Enable the option to protect the link. You can configure only two member links for an aggregated Ethernet interface, that is, one active and one standby. |
Non Revertive |
Select an option. It specifies not to switch links when higher priority link is available. |
Description |
Enter a description of the LAG. |
VLAN Tagging |
Select to enable VLAN tagging for a LAG. |
