Workflow to configure a mirror service

Prerequisites

The workflow lists the high-level steps required to configure a mirror service.

The workflow assumes the following:

  • A group or a customer with the required user access privileges has been configured.

  • The IP or IP/MPLS core network exists.

  • Any required service tunnels are created including the static, dynamic or SR-TE LSP required to create the service tunnel; see To create an IP/MPLS service tunnel .

  • The access ports for the service are created; see Chapter 16, Port and channel object configuration for more information.

  • Any required pre-defined routing, QoS, scheduling, filter, accounting, and time of day suite policies are created; see Chapter 49, Policies overview for more information. You do not have to create pre-defined policies if policies are created on a per-service basis.

  • Any required MP-BGP for PE-to-PE routing is configured; see Chapter 28, Routing protocol configuration for more information about protocol configuration.

  • The network services the mirror service will use are created.

  • A packet-sniffing device at the L2 SAP that is the destination of the mirror service is configured.

  • The SAP with the attached packet-sniffing device as the mirror destination is specified.

  • The source of the packets to be mirrored is configured.

Note: Note: The functionalities described in these procedures are device-dependent. Not all functionalities described in these procedures are supported by all devices.

Stages
 
1 

Create the mirror service. See To create a mirror service .

  1. Define the general properties for the mirror service.

  2. Specify the services for inclusion in the mirror service. You can specify multiple services in one operation.

  3. Enable one or more routing protocols for the mirror site.

  4. Create a destination site on the mirror service. See To create a destination site on a mirror service .

  5. Create a source site on the mirror service, if required. See To create a source site on a mirror service .

  6. Specify an endpoint on the site for redundancy, if required. See To create an endpoint for redundancy support on a mirror site .

  7. Create an L2 access interface on the destination site, if required. See To create an L2 access interface on a destination site .

  8. Specify one or more SAPs on the site as a mirror source, if required. See To specify a SAP on a mirror site as a mirror source .

  9. Specify one or more ports on the site as a mirror source, if required. See To specify a port on a mirror site as a mirror source .

  10. Specify one or more source IP filters, if required. See To specify a source IP filter entry as a mirror source .

  11. Specify one or more source IPv6 filters, if required. See To specify a source IPv6 filter entry as a mirror source .

  12. Specify one or more source MAC filters, if required. See To specify a source MAC filter entry for a mirror site .

  13. Specify one or more source MPLS ingress labels, if required. See To specify an MPLS ingress label as a mirror source .

  14. Turn up the mirror service.

As required, view mirror service information:

  1. View the service topology map associated with a Mirror Service. See To view the service topology associated with a mirror service .

  2. View the mirror service operational status. See To view mirror service operational status .

3 

As required, run an OAM validation test for a mirror service. See To run an OAM validation test for a mirror service .
