Think of a layer 3 switch. Assume that we have a management vlan and a mgmt vlan interface. And we have other svi's on the switch. The question is this. I know that mgmt vlan is for telnet/ssh, simply for connecting and managing the switch, but whats holding me from connecting to the switch through other svis. Whats the difference between the management svi and other svis?
If there is no ACL created on the line vty 0-4 that would restrict the access to this switch or router, then there is no difference between managment SVI's and other SVI's.
The management SVI/management network, is the the type of network from which the device is managed and where networking components are in. Source IP and destination IP define a management network. This is a network department specific configuration. If this is not defined then there is no difference.
Management SVI that is used for device management, have an IP address like as other SVIs. As per standard design, Vlans are terminated at distribution layer gateway IP address and SVIs IP address are no more visible at other part of network except service domain nodes, but management SVI IP address advertised to every part of network layers like core, super core including distribution and access layer with in network. So, network administrator can easily access to device using management SVI IP address.
