Application of Layer 2 Port Mirroring Types
You can apply different sets of Layer 2 port-mirroring properties to the VPLS packets at different ingress or egress points of an MX Series or of an EX Series route.
Table 1 describes the three types of Layer 2 port mirroring you can configure on an MX Series router and EX Series switch: the global instance, named instances, and firewall filters.
Table 1: Application of Layer 2 Port Mirroring Types
Type of Layer 2 Port Mirroring Definition | Point of Application | Scope of Mirroring | Description | Configuration Details | |
|---|---|---|---|---|---|
Global Instance of Layer 2 Port Mirroring | All ports in the MX Series router (or switch) chassis | VPLS packets received on all ports in the MX Series router (or switch) chassis | If configured, the global port-mirroring properties implicitly apply to all VPLS packets received on all ports in the router (or switch) chassis. | See Configuring the Global Instance of Layer 2 Port Mirroring | |
Named Instance of Layer 2 Port Mirroring | Ports grouped at the FPC level See Binding Layer 2 Port Mirroring to Ports Grouped at the FPC Level. | VPLS packets received on ports associated with a specific DPC or FPC and its Packet Forwarding Engines. | Overrides any port-mirroring properties configured by the global port-mirroring instance. | See Defining a Named Instance of Layer 2 Port Mirroring. NOTE: The number of port-mirroring destinations supported for an MX Series router and for an EX Series switch is limited to the number of Packet Forwarding Engines contained on the DPCs or FPCs installed in the router or switch chassis. | |
Ports grouped at the PIC level See Binding Layer 2 Port Mirroring to Ports Grouped at the PIC Level. | VPLS packets received on ports associated with a specific Packet Forwarding Engine. | Overrides any port-mirroring properties configured at the FPC level or in the global port-mirroring instance. | |||
Layer 2 Port-Mirroring Firewall Filter | Logical interface (including an aggregated Ethernet interface) | VPLS packets received or sent on a logical interface. | In the firewall filter configuration, include action and action-modifier terms to apply to the packets selected for mirroring:
| See Defining a Layer 2 Port-Mirroring Firewall Filter. NOTE: Layer 2 port-mirroring firewall filters are not supported for logical systems. For mirroring tunnel interface input packets to multiple destinations, also see Defining a Next-Hop Group for Layer 2 Port Mirroring. | |
VLAN forwarding table or flood table See Applying Layer 2 Port Mirroring to Traffic Forwarded or Flooded to a Bridge Domain. | Layer 2 traffic forwarded or flooded to a VLAN | ||||
VPLS routing instance forwarding table or flood table See Applying Layer 2 Port Mirroring to Traffic Forwarded or Flooded to a VPLS Routing Instance. | Layer 2 traffic forwarded or flooded to a VPLS routing instance | ||||
