MAC Limit for VPLS and H-VPLS
Overview
The MAC limit controls how many MAC addresses a system can learn, which is especially beneficial in Virtual Private LAN Service (VPLS) deployments. This control allows you to limit MAC addresses at more granular levels, such as the Access Circuit (AC) or Spoke-PW level, while maintaining the current VPLS instance-level limits.
Characteristics of MAC Move Limit - VPLS/H-VPLS
| • | Threshold-based control for the number of MAC addresses. |
| • | Granular configuration options, including interface/subinterface/AC/Spoke-PW levels. |
| • | Monitoring and enforcement with actions like logging or error-disable. |
| • | Security benefits by preventing MAC flooding and limiting device access. |
| • | Non-disruptive operation with logging, and optional error-disable with recovery options. |
Benefits
| • | Prevents MAC flooding attacks, controls access to network segments. |
| • | Improves network efficiency by managing memory and CPU usage. |
| • | Granular configuration at interface, subinterface, AC, and Spoke-PW levels. |
| • | Prevents MAC table overflows, ensuring stable traffic forwarding. |
| • | Syslog alerts and watermark thresholds for proactive management. |
| • | Logging doesn’t affect traffic, and error-disable includes recovery options. |
| • | Helps networks grow efficiently without overloading devices. |
