Configuring Ports and LAGs on AOS-CX

Link aggregation group (LAGLink Aggregation Group . A LAG combines a number of physical ports together to make a single high-bandwidth data path. LAGs can connect two switches to provide a higher-bandwidth connection to a public network. ) bundles multiple physical EthernetEthernet is a network protocol for data transmission over LAN. links into one logical link. Link aggregation has the following benefits:

• Increased bandwidth beyond the limits of single link. In an aggregate link, traffic is distributed across the member ports.
• Improved link reliability. The member ports dynamically back up one another. When a member port fails, its traffic is automatically switched to other member ports.

From the Ports and Link Aggregation page, you can view all the ports, configure LAGs, and modify port settings for AOS-CX switches using UI groups.

Following are the maximum number of LAGs that are supported on AOS-CX switches:

• AOS-CX 4100i, 6100 switch series—8
• AOS-CX 6200 switch series—32
• AOS-CX 6300 switch series—256
• AOS-CX 8320, 8360 switch series—54
• AOS-CX 8325 switch series—128

Adding a LAG

To add a LAG, complete the following steps:

1. In the Network Operations app, select one of the following options:
   • To select a switch group in the filter:
     1. Set the filter to a group.
        

        The dashboard context for the group is displayed.

     2. Under Manage, click Devices > Switches.
     3. Click the AOS-CX or Config icon to view the switch configuration dashboard.
   • To select a switch in the filter:
     1. Set the filter to Global or a group containing at least one switch.
     2. Under Manage, click Devices > Switches.
        

        A list of switches is displayed in the List view.

     3. Click an AOS-CX switch under Device Name.
        

        The dashboard context for the switch is displayed.

     4. Under Manage, click Device.
        

        The AOS-CX UI configuration page is displayed.

2. Click Interfaces > Ports & Link Aggregations.

   The Ports & Link Aggregations page is displayed with the list of ports configured on the switch.

   In the device view, all access ports are shown by default. Click the filter in the Name column to select All Uplink Ports or All Access Ports. You can also search for a port using the port name.

3. In the Ports & Link Aggregations table, click the + add icon to add a Lag. The Add Lag window is displayed.

When the maximum number of LAGs are added for a switch, the + add icon is disabled.

4. Configure the following parameters:>

   Table 1: Link Aggregation Parameters

   Name	Description	Value
   Name	Name of the LAG.	Name starting with the string lag. Example: lag1, Lag23, LAG123.
   Description	Description of the LAG.	A maximum of 64 characters including letters, numbers, and special characters, except question mark (?) and double quotes (").
   Port Members	The switch port members for the LAG.	Select from the drop-down list.
   Speed Duplex	The speed and duplex configuration for the client traffic. NOTE: Speed Duplex is shown or hidden depending on the value in Port Members field	Select from the drop-down list.
   Routing	Indicates whether routing is enabled. If routing is enabled at the device level, then specify the IP address with subnetSubnet is the logical division of an IP network. mask for the destination network. Format: (x.x.x.x/x). NOTE: If Routing is enabled at the device level, then port authentication configuration is reset on all the selected ports.	Toggle the switch to on or off position.
   VLAN Mode	The operational mode of VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.. This field is available only when Routing is disabled. In the access mode , port carries traffic only for the VLAN to which it is assigned. In the trunk mode, a port can carry traffic for multiple VLANs.	trunk or access For access mode, an Access VLAN can be specified. For trunk mode, the Native VLAN and Allowed VLANs can be configured. You can enter multiple Allowed VLANs by specifying the range of VLANs or VLANs separated by comma. For example, 1-7 or 55, 56, 57. NOTE: To specify the VLANs here, you must have already added the VLANs in the VLAN configuration page. See Configuring VLANs on AOS-CX.
   Admin Up	The operational status of the LAG. If the check box is selected, then the LAG can receive and transmit data as long as a cable is connected and no physical or operational problems exists.	Select the check box to enable.
   Aggregation Mode	The operational mode of link aggregation control protocol (LACPLink Aggregation Control Protocol. LACP is used for the collective handling of multiple physical ports that can be seen as a single channel for network traffic purposes.). LACP operates in these two modes: LACP active—When the LACP is operating in active mode on either end of a link, both ports can send Protocol Data Units (PDUs). The active LACP initiates an LACP connection by sending LACPDUs. LACP passive—When the LACP is operating in passive mode on a local member port and its peer port, both ports cannot send PDUs. The passive LACP will wait for the remote end to initiate the link.	None, LACP active, or LACP passive.

5. Click Add. The configured parameters are displayed in the Ports & Link Aggregations table.

Editing a LAG

To edit a LAG, point to the row for the LAG, and click the edit icon.

Deleting a LAG

Editing Ports settings

You can edit port settings by selecting one or more ports. If ports selected have different values configured, then changes made will be deployed on all the selected ports.

To edit ports, complete the following steps:
