A management virtual local area network (VLAN) is a much smaller network that is contained within your regular network. The primary benefit of using a management VLAN is improved network security. When all management traffic is on a separate VLAN, it is much harder for unauthorized users to make changes to your network or monitor network traffic.
Another potential benefit is that a management VLAN can help you minimize the impact of a broadcast storm on other VLANs by giving you a separate path to access your network.
On NETGEAR devices that support management VLANs, the management VLAN, VLAN 1, is also the native or default VLAN. By default, all ports are members of the default VLAN. For the management VLAN to be secure, it must only be used for controlling and managing your network devices; you must restrict access to the management VLAN and configure other VLANs to carry all regular network traffic.
If you decide to restrict access tothemanagement VLAN, especially with an access control list (ACL), make sure that you make your computer or device a member of the VLAN and add its MAC address to the ACL (if applicable). Otherwise, you must log in from an allowed device or lose access to the management functions of the switch. If you are unable to log in on an allowed device, you must reset the switch to factory default settingsto regain management access.
Using a management VLAN is not a substitute for physical security. NETGEAR recommends that you keep your networking devices (except access points) in a secure, temperature-controlled room with restricted access.

FAQs
A management VLAN is the VLAN that is used to remotely manage, control, and monitor the devices in you network using Telnet, SSH, SNMP, syslog, or Cisco's FindIT. By default, this is also VLAN 1. A good security practice is to separate management and user data traffic.
Should I have a management VLAN? ›
Security wise, you only allow specific access to the management vlan. (through acl on the router or firewall). It is good practice to put all your management devices (ilo, idrac, …) in this vlan. They should not be accessible by anyone except the ICT department in charge of those devices.
What is the purpose of a management VLAN on an HP provision switch? ›
Secure Management VLANs are designed to restrict management access to the switch to only those nodes connected to the Management VLAN.
How does a management VLAN increase security? ›
VLANs enhance network security by isolating segments, preventing unauthorized access and enabling specific security policies for each segment. This logical segmentation minimizes the risk of threats spreading across the network, offering efficient control and management for improved security measures.
What is management VLAN and data VLAN? ›
A management VLAN transmits packets that are forwarded through CAPWAP tunnels, including management packets and service data packets forwarded through CAPWAP tunnels. Typically, a management VLAN is the VLAN configured using the.
What is the default management VLAN? ›
The default VLAN continues to operate as a standard VLAN you cannot delete it or change its VID. Any ports not specifically assigned to another VLAN will remain assigned to the Default VLAN, even if it is the Primary VLAN.
Does the management VLAN need an IP address? ›
1 Management VLAN. To manage an Ethernet switch remotely through Telnet or the built-in Web server, the switch need to be assigned an IP address.
Should native and management VLAN be the same? ›
The management VLAN, which is VLAN 1 by default, should be changed to a separate, distinct VLAN. A recommended security practice is to change the native VLAN to a different VLAN than VLAN 1. The native VLAN should also be distinct from all user VLANs.
What type of VLAN is initially the management VLAN? ›
VLAN 1 is the management VLAN by default (VLAN 1 would be a bad choice for the management VLAN).
What devices should be on the management VLAN? ›
Just as your operations and your visitors are put on two (or more) VLANs to separate the network traffic, it is a best practice to use a separate management VLAN for the web and CLI* for your network equipment—router, switch(es), and access point(s). This way, users cannot access (and therefore hack) your hardware.
Management VLAN is used for managing the switch from a remote location by using protocols such as telnet, SSH, SNMP, syslog etc.
What does the management port on a switch do? ›
A management port can be used for remote management and configuration of a networking device, where as the Console Port can be used, in conjunction with a console server, such as Lantronix SLC 8000, to implement a separate dedicated network to access the network devices in case the primary network goes down.
What is the difference between primary VLAN and management VLAN? ›
The primary VLAN is the VLAN on which the switch expects to get its IP address via DHCP. The management VLAN is the VLAN on which it expects to receive management traffic like SNMP. (I personally agree with you that telnet/ssh/web should be disabled on other VLANs also, but they're not.)
Is a management VLAN used to remotely access and configure a switch? ›
A management VLAN is used to remotely access and configure a switch. Data VLANs are used to separate a network into groups of users or devices. The default VLAN is the initial VLAN all switch ports are placed in when loading the default configuration on a switch.
What are some common VLAN security mistakes? ›
What are the common mistakes and pitfalls to avoid when configuring VLAN ACLs?
- Misunderstanding the direction of traffic. ...
- Using standard ACLs instead of extended ACLs. ...
- Forgetting to permit or deny implicit traffic. ...
- Applying the wrong ACL to the wrong VLAN. ...
- Not testing or troubleshooting the ACLs.
The management VLAN communicates with the main switch interface and has a default VLAN ID of 1. A tagged VLAN between a trunk port and a switch port contains the VLAN information in the Ethernet frame. The untagged VLAN is enabled to send traffic without the VLAN tag.
