The SLX-OS platform provides a mechanism to collect and send important data at regular intervals to external equipment for monitoring and analysis purposes.
MPLS LSP Ingress statistics data is streamed using telemetry streaming. In order to configure telemetry streaming, you must configure the necessary telemetry profile along with the necessary fields. The streaming is initiated when the client initiates an RPC call with the telemetry profile name.
You can configure MPLS traffic statistics data from the MPLS LSP, Bypass LSP, or LDP FEC Address to be streamed. Three different types of data streaming profiles are supported for streaming the data related to MPLS traffic, with counters having out-packets and out-bytes attributes. MPLS statistics in the system take a 4 minute interval to get refreshed.
Transit MPLS statistics streaming is not supported. Tunnel-ID based streaming and In-Label based streaming is not supported. Streaming is supported for up to 5000 RSVP LSPs and 500 Bypass LSPs.
- The profile is indexed based on the LSP name.
- The interval has a default value of 240 seconds and a range of 240 to 3600 seconds.
- By default, the profile is not active.
- The streamed data consists of out-packets and out-bytes.
- A maximum of 5000 entries per system can be streamed.
- The data size is 84 bytes per entry.
- The profile is indexed based on the Bypass LSP name.
- The interval has a default value of 240 seconds and a range of 240 to 3600 seconds.
- By default, the profile is not active.
- The streamed data consists of out-packets and out-bytes.
- A maximum of 500 entries per system can be streamed.
- The data size is 84 bytes per entry.
- The profile is indexed based on the valid MPLS LDP FEC.
- The interval has a default value of 240 seconds and a range of 240 to 3600 seconds.
- By default, the profile is not active.
- The streamed data consists of out-packets and out-bytes.
- A maximum of 5000 entries per system can be streamed.
- The data size is 20 bytes per entry.
All of the three profiles are default profiles that get automatically configured while system is coming up. Default profiles cannot be deleted by users.
You can add or delete the default profile parameters, such as interval, lsp/bypass-lsp/fec, out-packets and out-bytes.
MPLS traffic data streaming is developed using existing MPLS statistics features and existing gRPC streaming/Collector features. Thus, the MPLS statistics capabilities and the limitations pertaining to statistics collection remain. Existing gRPC streaming/Collector capabilities and the limitations pertaining to statistics collection remain also.
Note
The MPLS ingress tunnel accounting or Auto bandwidth feature must be enabled to enable MPLS statistics to be collected.
