Re: what is Management VLAN ??

A vlan which is used purely for management of network devices.

Therefore, no customer traffic should be on the management vlan, just management traffic.

it's vlan 1 or the default vlan on a switch where ports are all initially assigned

Re: what is Management VLAN ??

As Michael notes, this VLAN exludes customer traffic, or in other words, no "normal" user traffic, would be on this VLAN, only network system traffic.

Examples include: the device's management address, CDP, SNMP, RMON, STP BPDUs (if not per VLAN), etc.

The purpose is for both security and performance. Security might be obvious, as a different VLAN, we limit what traffic can access the network device as a host. For performance, just as with VLANs in general, we limit what broadcasts the network device will see and minimize traffic directed to the device's management port (e.g. multicast w/o snooping).
