How do I enable port security on a dynamic port?

How do I enable port security on a dynamic port?

Configuration Steps:

1. Your switch interface must be L2 as “port security” is configure on an access interface.
2. Then you need to enable port security by using the “switchport port-security” command.
3. This step is optional, but you can specify how many MAC addresses the switch can have on one interface at a time.

Is a dynamic port?

A port that can be used by any computer application program to communicate with any other application program running Transmission Control Protocol (TCP) or User Datagram Protocol (UDP), with no registration requirements. Dynamic ports are numbered from 49,152 through 65,535.

What does the Switchport port security command do?

The switchport security feature (Port Security) is an important piece of the network switch security puzzle; it provides the ability to limit what addresses will be allowed to send traffic on individual switchports within the switched network.

What are the port security violation modes?

You can configure the port for one of three violation modes: protect, restrict, or shutdown.

2. enable port security by using the switchport port-security interface subcommand.

How do I check my dynamic ports?

2. netsh int ipv4 show dynamicport udp.
3. netsh int ipv6 show dynamicport tcp.
4. netsh int ipv6 show dynamicport udp.

What causes port security violation?

A security violation occurs when the maximum number of MAC addresses has been reached and a new device, whose MAC address is not in the address table attempts to connect to the interface or when a learned MAC address on an interface is seen on another secure interface in the same VLAN.

What is Switchport port security violation protect?

Protect – When a violation occurs in this mode, the switchport will permit traffic from known MAC addresses to continue sending traffic while dropping traffic from unknown MAC addresses. When using this mode, no notification message is sent when this violation occurs.

What is dynamic port security?

Dynamic – Dynamic secure MAC addresses are learned from the device (or devices) connected to the switchport. These addresses are stored in the address table only and will be lost when the switchport state goes down or when the switch reboots.
