5.8 VLAN (Bridge Mode Only)
The Virtual Local Area Network (VLAN) feature helps in logical grouping of network host on different physical LAN segments, which
can communicate with each other as if they are all on the same physical LAN segment.
With VLANs, you can conveniently, efficiently, and easily manage your network in the following ways:
• Define groups
• Reduce broadcast and multicast traffic to unnecessary destinations
- Improve network performance and reduce latency
• Increase security
- Secure network restricts members to resources on their own VLAN
The SUs and End Point devices support QinQ VLAN feature that enables service providers to use a single VLAN ID to support
multiple customer VLANs by encapsulating the 802.1Q VLAN tag within another 802.1Q frame. The benefits with QinQ are,
• Increases the VLAN space in a provider network or enterprise backbone
• Reduce the number of VLANs that a provider needs to support within the provider network for the same number of
customers
• Enables customers to plan their own VLAN IDs, without running into conflicts with service provider VLAN IDs
• Provides a simple Layer 2 VPN solution for small-sized MANs (Metropolitan Area Networks) or intranets
• Provides customer traffic isolation at Layer 2 within a service provider network
: VLAN can be configured in Bridge Mode only.
5.8.1 System-Level VLAN Configuration
To configure system-level VLAN parameters, navigate to ADVANCED CONFIGURATION > VLAN. The VLAN configuration
screen appears.
Figure 5-53 System-Level VLAN Configuration
1. VLAN Status: This parameter is used to either enable or disable VLAN feature on the device. By default, this
parameter is disabled. To enable VLAN, select the VLAN Status box. If VLAN status is enabled, it indicates that locally
configured VLAN parameters will be applied on the device. If VLAN status is disabled, it indicates that the device is open for
remote VLAN configuration.
2. Management VLAN Id: This parameter enables the user to configure VLAN Id for management frames (SNMP, ICMP,
Telnet and TFTP). The stations that manage the device must tag the management frames with the management VLAN
Id. By default, the Management VLAN Id is set to -1 which indicates no tag is added to the management frame. To set
VLAN tag to the management frame, enter a value ranging from 1 to 4094.
