Technical Field
The present application relates to an ethernet passive optical network technology, and in particular, to a method and an apparatus for collecting monitoring packets.
Background

The EPON network adopts PON technology on a physical layer, uses an Ethernet protocol on a data link layer and realizes Ethernet access by utilizing a topological structure of the PON.
When an EPON Network fails, a professional PON (Passive Optical Network) analyzer needs to be connected between an OLT (Optical Line Terminal) and an ONU (Optical Network Unit) to capture an OAM (Operation, Administration, and Maintenance) message to analyze the failure. However, this method has a disadvantage that the PON analyzer cannot intelligently analyze the OAM message to analyze the OAM message corresponding to the configured OAM command.

Fig. 1 shows an embodiment of a method for collecting management packets, which includes the following steps:
103, when the message type of the operation management maintenance message is the message type carrying the fault data of the optical network unit, analyzing the fault data of the specified field of the operation management maintenance message corresponding to the fault monitoring type of the optical network unit;
and step 104, mirroring the operation, management and maintenance message to a network interface connected with the collector.
The method and the device have the advantages that the OAM message from the ONU is monitored through the optical line terminal OLT of the EPON, so that the state of the EPON is monitored in real time, the positioning efficiency of the problems of the EPON is greatly improved, and the stability of the EPON is improved.
Fig. 2 is a schematic diagram of a monitoring operation management maintenance message mechanism provided in the present application; an OLT device embedded SOAM (supervisory OAM) Agent and a remote SOAM Collector. The SOAM Agent of the OLT mirrors OAM data which is sent to the ONU by the OLT needing to be monitored and OAM data received from the ONU to the Ethernet port through an ACL (access control list).
Specific OAM messages are monitored by configuring monitoring instructions on the OLT, such as monitoring loop monitoring OAM message instructions and monitoring ONU internal fault report OAM message instructions.
Because the number of the ONUs in the network is large, in order to reduce the phenomenon that the CPU load of the OLT is too large when the OLT monitors a specific OAM message, the OAM message for monitoring the specified ONU can be set.
And the OLT generates mirror image ACL list items according to the configured monitoring instructions, and mirrors the OAM messages conforming to the monitoring OAM instructions to the Ethernet port connected with the Collector.
According to the method and the device, data to be monitored are carried by using the extended OAM and the extended private OAM, and ONU fault data are carried by using the extended private OAM. The OLT may identify whether the received OAM message is an extended private OAM according to a vendor identifier carried in an OUI (organization unique identifier).
When an OLT receives an OAM message, analyzing an Ext.Opcode field which represents an extended operation type (get, set, auth, event and the like) and a Branch field which represents an attribute of an extended object (generally, the extended attribute is an extended attribute, and get and set can be executed, and 0xC7) wherein the OAM message is an analysis message type; and (3) determining that the action behavior of the OAM message accords with the configured monitoring instruction by using a Leaf field for expressing the operation management (specific action) of the extended object, and copying and caching the OAM message.
Similarly, when receiving the OAM message, the OLT distinguishes that the OAM message is an extended private OAM message according to the OUI field, determines that the action behavior of the extended private OAM message conforms to the configured monitoring instruction according to the PDU _ TYPE field and the REQ _ ID field of the private OAM message, and copies one for caching.
The OAM messages received by the OLT are all provided with LLID (Logical Link ID); if the LLIDs of the appointed ONUs of the configured monitoring instruction are the same, identifying the type of the OAM message as an expanded OAM message or a private OLT receives the OAM message, analyzing the action behavior of the OAM message to be in accordance with the configured monitoring instruction, and copying and caching the OAM message.
And when the expanded OAM message and the expanded private OAM cached by the OLT reach a caching threshold value or a timer of the OAM from the OLT to the collector arrives, sending the cached OAM message and the expanded private OAM to the collector.
In the application, the OLT does not buffer the ONU faults transmitted by the extended private OAM message, but directly copies one part of the ONU faults and mirrors the part of the ONU faults to the Ethernet port connected with the collector
In the application, in an OAM message for monitoring an ONU fault, a PDU _ TYPE field needs to be filled with "EOAM _ EVENT", and REQ _ ID to distinguish fault TYPEs, and different faults can be identified by agreeing on an ID value. For example, an ID value of 0xf1 indicates that the CPU utilization exceeds 90%, an ID value of 0xf2 indicates that the ONU memory threshold is reached, and an ID value of 0xf3 indicates that the upstream traffic is congested.
When the ONU has a fault which needs to be reported immediately, the ONU directly sends an extended private OAM message with a fault type to the OLT, and the OLT directly sends the message to the collector after receiving the message and analyzing the message.
When the OLT receives the OAM message, the OAM message is an extended private OAM message according to the resolution of the OUI field, the extended private OAM message is determined to carry ONU fault data according to the PDU _ TYPE field and the REQ _ ID field of the private OAM message, a copy of the received extended private OAM message is immediately copied, and the extended private OAM message is connected with an Ethernet port of the collector to be sent, so that the message with the ONU fault data is immediately mirrored to the collector.
