To remotely manage the device, an IP address must be defined to access the switch. This is a fundamental process for accessing the switch's web configuration interface and making the necessary configurations for proper network operation. A Cisco switch gets its management IP on an SVI (usually VLAN 1 or a dedicated mgmt VLAN).

The IP Limit feature restricts user-based IP addresses that can log in to a device. we've Cisco core switch and wanted to limit ssh access to specific SVI interface, at the moment we've a standard ACL configured for limiting source addresses who can access core switch through ssh, in addition to that we wanted only one of the SVIs to be accessed through ssh and tried below configs. Router on a Stick is best used in a small office environment, and not a large campus, or similar environment where multiple servers are located. Using a WAN router or Firewall as your routing device for your LAN (the router on the stick) means each user must be routed by that device to get to the. The core switch is a high-end device that is used to connect all the access switches. Since each interface module provides a certain number of ports, the number of slots fundamentally determines the number of ports that the switch can support.

When you start a switch, it reads the startup configuration and loads it into RAM as the running configuration. And this process is a little more advanced than, say, setting up your home Internet or even a plug-and-play type switch. Although a Cisco switch is a much simpler network device compared with other devices (such as routers and firewalls for example), many people have difficulties to configure a Cisco Catalyst Switch.
