Mirror source and destinations

Mirror sources and destinations have the following characteristics for 7210 SAS devices operating in network mode:

• Mirror source and mirror destination can be on the same node (local mirroring) or on different nodes (remote mirroring).

• Each mirror destination should terminate on a distinct port carrying only null encapsulation or a Dot1q SAP or a Q1.* SAP or a MPLS SDP in case of remote mirroring.

• Packets ingressing a port can have a mirror destination separate from packets egressing another or the same port (the ports must be on the same node).

• Multiple mirror destinations are supported (local only) on a single chassis.

Listed below are the mirror source and destination characteristics for 7210 SAS devices configured in access-uplink mode:

• Mirroring source and destination needs to be on the same node (that is, only local mirroring is supported).

• A mirror destination can terminate on only one port (NULL SAP or dot1q SAP or a Q1.* SAP).

• Packets ingressing a port can have a mirror destination separate from packets egressing another or the same port.

The following table lists the combinations of SAPs, spoke SDPs, and remote sources allowed in a mirror service using different mirror-source-type on 7210 SAS devices configured in network mode.
