Understanding the Mechanisms of Port Security on the Catalyst 9200

Port security functions by limiting the number of MAC addresses allowed on a particular switch port and by specifying which MAC addresses are permittedSwitchport Port-Security When a device is connected to a port with port security enabled, the switch learns the MAC address of that device and associates it with that specific portCISCO-PORT-SECURITY-MIB. CISCO-PORT-STORM-CONTROL-MIB. CISCO-POWER-ETHERNET Catalyst920024-port PoE+ Switch. Network Essentials.C9200-24PB-A. This provides a fundamental layer of security by preventing rogue devices from simply plugging into an open port and gaining access to the networkSecure your campus LAN access layer with Ciscoport security. Learn how to limit MACs, block rogue devices, and recover err-disabled switchports.

The Cisco Catalyst 9200 Series offers several configurable options for port security, allowing for a tailored approach to network defense2021626—1.1 Purpose. This document is the non-proprietary Cryptographic ModuleSecurityPolicy for the Cisco Catalyst9200Series. Key parameters you can configure include:

* Maximum MAC Addresses: You can set a limit on the number of MAC addresses that can be learned on a portSecure your campus LAN access layer with Ciscoport security. Learn how to limit MACs, block rogue devices, and recover err-disabled switchports. Typically, this is set to one for enhanced security, ensuring only a single authorized device can connectCisco Catalyst 9200 Series Multi-Gigabit Switches

* Violation Actions: When a port security violation occurs (eUsing Port Security on Cisco Switch - NetworkinggUnable to connect to Elasticsearch at http//localhost9200, an unauthorized MAC address is detected, or the maximum MAC address limit is exceeded), the switch can take predefined actions2021626—1.1 Purpose. This document is the non-proprietary Cryptographic ModuleSecurityPolicy for the Cisco Catalyst9200Series. These actions include:

* Shutdown: The port is automatically disabled, and an administrator must manually re-enable itC9200-24T-A | Cisco Catalyst 24-Port Gigabit Switch This provides a high level of security but requires manual intervention201758—security.enabled false and this is my elastics bat command, then scroll down to localport 9200, and check if you have Java listening onport

* Restrict: The port drops all traffic from unauthorized MAC addresses but continues to send SNMP trap notifications and increments the security violation counterSecure your campus LAN access layer with Ciscoport security.

* Protect: The port drops all traffic from unauthorized MAC addresses but does not send any notifications or increment the security violation counter This is the least secure option and is generally not recommended for most security scenariosCisco Catalyst 9200 Series Multi-Gigabit Switches

* Aging Time: This setting determines how long learned MAC addresses remain in the switch's address table2021626—1.1 Purpose.

You can configure switchport port-security aging time to be either static (the address remains until manually cleared) or dynamicCisco Nexus 9000 Series NX-OS Security Configuration With dynamic aging, you can also specify an aging type, such as inactivity, where learned addresses are removed after a period of no traffic from that MACCisco Switch Port Security ---How to Configure Switch Security?

Advanced Security Features on the 9200 Series

Beyond standard port security, the Cisco Catalyst 9200 Series also incorporates other advanced security features that contribute to a comprehensive network defense strategyCisco Catalyst 9200 Series Multi-Gigabit Switches These can include AES-128 MACsec encryption on models like the C9200-24T-A, which provides secure, encrypted communication between switchesCisco Catalyst 9200 Series Multi-Gigabit Switches Furthermore, features like storm control (indicated by CISCO-PORT-STORM-CONTROL-MIB) help to mitigate the impact of network storms caused by broadcast, multicast, or unicast traffic, preventing network degradation and potential denial-of-service scenariosC9200-24T-A | Cisco Catalyst 24-PortGigabit Switch.

Implementing and Managing 9200 Port Security

When configuring 9200 port security, administrators often follow a process of defining secure ports and managing potential violations2012227—Conventional networksecurityoften focuses more on routers and blocking traffic from the outside. Switches are internal to the organization  The ability to restrict rogue devices is a primary benefit of this featureSwitchport Port-Security In scenarios where a port security violation occurs, the err-disabled switchports need to be addressedUnable to connect to Elasticsearch at http//localhost9200 This can involve investigating the cause of the violation, such as an unauthorized device connection, and then re-enabling the port after the issue has been resolvedCISCO-PORT-SECURITY-MIB.
