Port Mirroring and Monitoring

In this section:

  1. Port Mirroring and Monitoring Overview
  2. Port Mirroring and Monitoring Configuration
  3. Mirroring Configuration on a Traditional Stack
  4. ACL-based Inbound Mirroring
  5. MAC ACL Mirroring
  6. VLAN-based Mirroring
  7. Remote Switched Port Analyzer
    Remote Switched Port Analyzer (RSPAN) enables remote monitoring of multiple switches across a network. When RSPAN is enabled, a copy of each incoming or outgoing packet from one port on a network switch is forwarded to another port on the same switch where the packet can be analyzed. RSPAN can be used as a diagnostic tool for preventing network attacks.
  8. Configuring VLAN-based filtering for SPAN or RSPAN
  9. Encapsulated Remote Switched Port Analyzer
    Encapsulated Remote Switched Port Analyzer (ERSPAN) mirrors traffic across Layer 3 networks using Generic Routing Encapsulation (GRE) tunneling, allowing you to analyze packets on a device not directly connected to the switch.
