Configuring VLANs on AOS-CX

VLANs Virtual 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. are primarily used to provide network segmentation at layer 2. VLANs enable the grouping of users by logical function instead of physical location. VLANs help managing bandwidth usage within networks by:

• Allowing grouping of high-bandwidth users on low-traffic segments.
• Organizing users from different LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments according to their need for common resources and individual protocols.
• Improving traffic control at the edge of networks by separating traffic of different protocol types.
• Enhancing network security by creating subnets Subnet is the logical division of an IP network. to control in-band access to specific network resources.

From the VLANs page, you can add VLANs and manage VLAN settings such as name, description, admin status, and IP assignment for AOS-CX switches.

For AOS-CX 6200 and 6300 switch series, VLAN 1 (DEFAULT_VLAN_1) is associated with all interfaces on the switch. The DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  assignment of the IP address is available only on the default VLAN.

Adding a VLAN

To add a VLAN, complete the following steps:

1. In the WebUI, 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 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 Bridging > VLANs.

   The VLANs page is displayed with a list of VLANs.

3. In the VLANs table, click + to add a VLAN and configure the following parameters.

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

   Name	Description	Value
   ID	The VLAN ID number.	Following are the different ranges for the VLANs supported on switches: AOS-CX 4100i, 6100 switch series—2 to 512 AOS-CX 6200 switch series—2 to 2048 AOS-CX 6300 and 8360 switch series—2 to 4094 AOS-CX 8320 and 8325 switch series—2 to 4040 At the group level, the maximum VLANs supported is 4094 NOTE: AOS-CX 6400 and 8400 switch series are not supported in Classic Central UI configuration.
   Name	The name of the VLAN.	Only letters (a-z) and numbers (0-9) are allowed.
   Description	The description of the VLAN.	Letters, numbers, and special characters are allowed except question mark (?) and double quotes (").
   Admin UP	The operational status of the VLAN. The VLAN can forward packets only when the check box is selected.	Select the check box to enable.
   Voice	The VLAN support for voice.	Select the check box to enable.
   IP Address Assignment	The method of IP assignment. The option to enter the IP address is displayed only when you select Static. This field is available only at the device level. NOTE: The DHCP option is available only for the default VLAN on AOS-CX 6100, 6200, and 6300 switch series.	Static, DHCP, or None. Default: None
   IP Address	The IP address with a subnet mask for IP assignment. This field is enabled only when you select Static from the IP address assignment drop-down and available only at the device level.	IPv4 address or IPv6 address with subnet mask. Format: (x.x.x.x/x).
   DHCP Relay	The IP address of the DHCP relay server. This field is enabled only when you select DHCP or Static from the IP address assignment drop-down and available only at the device level. NOTE:   AOS-CX 6100 and 6200 switch series—DHCP relay is not supported AOS-CX 6300 switch series—DHCP relay is available only on the default VLAN	IPv4 address.

4. Click Add.

   The VLAN information is displayed in the VLANs table.

Editing a VLAN

To edit a VLAN, point to the row for the VLAN, and click the edit icon. You can select only one VLAN at a time for editing.

Deleting a VLAN

To delete a VLAN, point to the row for the VLAN, and click the delete icon. Deleting VLAN at the device level and modifying configuration at group level will not add the VLAN again on the device. You can select only one VLAN at a time for deleting.
