  • The optical port of the switch becomes clogged after prolonged use

    The optical port of the switch becomes clogged after prolonged use

    Verify switch port configuration If optical attenuation is normal but the link still fails, check the switch port settings: • Some switches use combo SFP/RJ45 ports, which require manual optical port configuration. • Some ports are multi-rate multiplexed (e. The transmitted optical power is too low or too high. The optical modules connected at both. Based on typical issues encountered with optical modules in daily switch applications, this document summarizes basic troubleshooting steps for resolving common faults: 1. In both devices, we have experienced episodes of SFP port lockup, requiring a full reboot of the switch to restore connectivity — even applying shutdown / no shutdown on the affected interface does not resolve the issue. Maintenance personnel should regularly check for loose, contaminated, or damaged ports to ensure proper fiber jumper connections. This is typically due to one of the following failures: hardware defect, poor seating, or incompatibility.

  • Security Configuration of Core Switch Ports

    Security Configuration of Core Switch Ports

    In this lesson, you will learn how to configure port security to restrict the number of MAC addresses per port, specify which MAC addresses are allowed, and control what happens when violations occur. To understand port security, you should be familiar with how switches learn MAC. Which means to security architecture must implement with different layers of security levels such that firewalls, intrusion preventing system, antivirus and antimalware tools for end user devices, IP access control lists to filter packets on routers and there are many more. The maximum number of secure MAC addresses that you can configure on a switch is set by the maximum number of available MAC addresses allowed in the. To block unauthorized access to switch ports, switches support a feature called port security. This tutorial explains. On Cisco Catalyst switches, port security is a per-interface feature that enforces a limit and a list of allowed MAC addresses. If a device connects and its MAC is allowed, all good. This can be a security risk when users connect.
