How does a management VLAN increase security?
Because VLANs support a logical grouping of network devices, they reduce broadcast traffic and allow more control in implementing security policies. Also, surveillance traffic is only available to those authorized, and bandwidth is always available, when needed.
What is difference between access and trunk mode?
A trunk port has more than one VLAN set up on the interface, whereas an access port is capable of having only one VLAN set up on the interface. Trunk port usually offers higher bandwidth and lower latency than access ports. Voice VLAN feature is supported only on the access Port, not on the trunk port.
When do I need to set a management VLAN?
Management VLANs should generally be configured last (after devices), because once you set a network device to use a VLAN, you will lose access to the device until its PC port connects to the same VLAN.*** To ensure connection, make sure the PC port used by the device is configured to the management VLAN used by the device.

Do you need a VLAN for an SVI?
For an interface VLAN ( or SVI) to be up/up, you need 3 things: 1) the VLAN must exist in the vlan database which is the case as it is the default vlan. 2) it must be active on one port,whether access port or trunk. 3) that port must be in the stp forwarding state.
