The port can be re-activated after the configured time by configuring the auto-recovery option. By enabling, the RA packets received on the interface are dropped and the port can be shutdown based on the interface configuration. The RA guard feature is disabled by default. The Router Advertisement (RA) Guard functionality analyzes the RAs and filters out RA packets sent by unauthorized devices. You can enable or disable this functionality at an interface level. You can now filter the unauthorized devices to send the control packets, restrict the number of MACs allowed on the interface, and detect unwanted loops in the network when not running spanning-tree protocol. This release of ArubaOS Mobility Access Switch supports Port Security functionality which provides network security at Layer 2. This mode is enabled by default and port state is changed to error-disabled, which restricts connected device to perform any function and also disables that particular port.Port Security Overview Port Security Overview Also, logs are generated simultaneously, to check, which device was connected with Cisco switch. When this mode is enabled and port security is violated, all the data transfer is blocked and packets are dropped.

Under this mode, data packets from defined MAC addresses are only transferred within the network. Three primary predefined modes can be used, which are Protect, Restrict and Shutdown. This feature is used to define the action, which will be executed by switch, whenever port security is violated. By this, now five devices can be connected to a port and perform their functions.Ĭisco IOS Switch offers a security feature, which is known as violation. To increase the number of users on a single port, ‘switchport port-security maximum 5’ command is executed. These commands must be executed, whenever any other port is interfaced and port security needs to be enabled on it.īy default, only 1 MAC address is allowed by the Cisco switch on a single port and if any other device tries to connect using that port, switch automatically shutdown its port to restrict unauthorized access. Then, ‘switchport mode access’ and ‘switchport port-security’ commands are executed to change the port mode to access and enable security respectively. This security feature of Cisco IOS Switches can only be configured on access ports and by default, this feature is disabled.īelow provided steps and commands can be used to enable Port Security on Cisco Switch, which ensures that data confidentiality, authenticity and integrity is maintained.Īt first, Command Line Interface of Cisco switch is accessed and a port Gigabit Ethernet 0/1 is interfaced using ‘interface Gigabit Ethernet 0/1’ command. Before configuration of any switch in an organizational network, port security is considered, as it ensures that authentic and authorized user is connected within the network. It is a crucial task to secure these ports, so that only authorized users are able to connect their systems into the network through a switch. MAC address of these connected devices is used by switch to identify them and provide them with the requested service. To connect all these network, Ethernet cables are used. Ethernet ports are present on a switch, which are used to connect devices, such as Router, computer system and Laptop in the network. Switch is a network device, which is configured to connect and maintain communication channel between various devices. Difference between em and rem units in CSS.
