Debugging auto-attach entities (client and proxy) using connectivity fault management (CFM) and shortest path bridging MAC (SPBM) cloud
View Patent ↗A computer-implemented method, apparatus and software for debugging auto-attach entities is presented. A Continuity Fault Management (CFM) request for a service is received over a network at an Auto-Attach (AA) server. The AA server responds with a first response regarding the AA server on the service. The AA server also responds to the CFM request with a second response regarding any AA clients and any AA proxies on the service.
1. A computer-implemented method in which a computer system performs operations comprising:
receiving, at an Auto-Attach (AA) server, a Continuity Fault Management (CFM) request
for a service over a network, wherein said service over said network is mapped to a Service Instance Identifier (I-SID);
responding, by said AA server, with a first response regarding said AA server on said
service mapped to said I-SID, to said CFM request; and
responding, based on information stored on said AA server, by said AA server on behalf of any AA client and any AA proxy on said service that is mapped to said I-SID without transmitting said CFM request to said any AA client and said any AA proxy, with a second response regarding said any AA client and said any AA proxy on said service, to said CFM request, wherein said second response includes a Type, Length, Value (TLV) having an identifier of said any AA client device and said any AA Proxy.
2. The method of claim 1 wherein said AA server comprises a Backbone Edge Bridge (BEB) connected to a Shortest Path Bridging (SPB) network.
3. The method of claim 1 wherein said second response includes a Type, Length, Value (TLV) having a list of ports that have client devices and proxy devices.
4. The method of claim 1 further comprising using, by a device sending said CFM request, said responses to determine a presence of a rogue device attached to said network.
5. The method of claim 1 further comprising using, by a device sending said CFM request, said responses to confirm a configuration of devices on said network.
6. A non-transitory computer readable storage medium having computer readable code thereon for debugging auto-attach entities (client and proxy) using Connectivity Fault Management (CFM) and Shortest Path Bridging MAC (SPBM) cloud, the medium including instructions in which a computer system performs operations comprising:
receiving, at an Auto-Attach (AA) server, a Continuity Fault Management (CFM) request for a service over a network, wherein said service over said network is mapped to a Service Instance Identifier (I-SID);
responding, by said AA server, with a first response regarding said AA server on said service that is mapped to said I-SID, to said CFM request; and
responding, based on information stored on said AA server, by said AA server on behalf of any AA client and any AA proxy on said service without transmitting said CFM request to said any AA client and said any AA proxy, with a second response regarding said any AA client and said any AA proxy on said service, to said CFM request, wherein said second response includes a Type, Length, Value (TLV) having an identifier of said any AA client device and said any AA Proxy.
7. The computer readable storage medium of claim 6 wherein said AA server comprises a Backbone Edge Bridge (BEB) connected to a Shortest Path Bridging (SPB) network.
8. The computer readable storage medium of claim 6 wherein said second response includes a Type, Length, Value (TLV) having a list of ports that have client devices and proxy devices.
9. The computer readable storage medium of claim 6 further comprising using, by a device sending said CFM request, said responses to determine a presence of a rogue device attached to said network.
10. The computer readable storage medium of claim 6 further comprising using, by a device sending said CFM request, said responses to confirm a configuration of devices on said network.
11. A computer system comprising:
a memory;
a processor;
a communications interface; and
wherein the memory is encoded with an application for debugging auto-attach entities (client and proxy) using Connectivity Fault Management (CFM) and Shortest Path Bridging MAC (SPBM) cloud, that when performed on the processor, provides a process for processing information, the process causing the computer system to perform the operations of:
receiving, at an Auto-Attach (AA) server, a Continuity Fault Management (CFM) request for a service over a network, wherein said service over said network is mapped to a Service Instance Identifier (I-SID);
responding, by said AA server, with a first response regarding said AA server on said service that is mapped to said I-SID, to said CFM request; and
responding, based on information stored on said AA server, by said AA server on behalf of any AA client and any AA proxy on said service without transmitting said CFM request to said any AA client and said any AA proxy, with a second response regarding said any AA client and said any AA proxy on said service, to said CFM request, wherein said second response includes a Type, Length, Value (TLV) having an identifier of said any AA client device and said any AA Proxy.
12. The computer system of claim 11 wherein said AA server comprises a Backbone Edge Bridge (BEB) connected to a shortest Path Bridging (SPB) network.
13. The computer system of claim 11 wherein said second response includes a Type, Length, Value (TLV) having a list of ports that have client devices and proxy devices.
14. The computer system of claim 11 further comprising using, by a device sending said CFM request, said responses to determine at least one of a group consisting of a presence of a rogue device attached to said network, and a configuration of devices on said network.
