1. A method, comprising:
- selecting an operation, administration, and maintenance (OAM) type for a destination, wherein the destination is enabled for a service insertion architecture (SIA), wherein the SIA comprises a service classifier that is configured to redirect packets to one or more of a plurality of service nodes for servicing;
encapsulating an OAM packet with the OAM type indicated in a service header of the OAM packet, the OAM type designating an OAM function to be performed using the OAM packet, wherein the OAM type is selectable from normal, SIA trace, SIA echo, and continuity check;
sending the OAM packet to the destination by traversing at least one of the plurality of service nodes; and
receiving a reply packet from the destination, wherein the reply packet includes information indicating performance of the OAM function.

11. A method, comprising:
-
receiving an operation, administration, and maintenance (OAM) packet in a device enabled for a service insertion architecture (SIA), wherein the SIA comprises a service classifier that is configured to redirect packets to one or more of a plurality of service nodes for servicing, the OAM packet having traversed at least one of the plurality of service nodes; parsing an OAM type from a service header in the OAM packet, wherein the OAM type is selectable from normal, SIA trace, SIA echo, and continuity check; performing an OAM function designated by the OAM type and using the OAM packet; and sending a reply packet to a source node or a next node, wherein the reply packet includes reply information based on the OAM type to indicate performance of the OAM function. - View Dependent Claims (12, 13, 14, 15, 16)
