When Failed to Create ATM Services

ATM services fail to be created, thus failing to realize the protection. You need to add the two connections into the protection group.

Product

Fault Type

Configuration_Problem

Symptom

After you create two connections that have the same source but different sinks, or that have the same sink but different sources, the service of a connection fails to be created.
The service fails to be created. The protection fails to be achieved accordingly.

Cause Analysis

The second connection takes effect only after you add the two connections that have the same source but different sinks, or that have the same sink but different sources into the protection group.

Procedure

  1. Add the two connections into the protection group.

Reference Information

None.

How to do when Mismatching Between MA Groups and Associated VCTRUNKs, Hence Causing the Binding Failure?

IMA groups fail to be bound with associated VCTRUNKs. You need to configure IMA groups to match with associated VCTRUNKs.

Product

Fault Type

Configuration_Problem

Symptom

The principle of binding VCTRUNKs is met, but VCTRUNKS fail to be bound.

Cause Analysis

Mutual check relation exists between IMA groups and associated VCTRUNKs.

Procedure

  1. If IMA groups are symmetrically configured, make sure that the mapping VCTRUNKs are symmetrical.
  2. If VCTRUNKs are nonsymmetrical, make sure that the mapping IMA groups are nonsymmetrical.

Reference Information

None.

Failing to Create the 622 Mbit/s Service

The ATM 622 Mbit/s service fails to be created. You need to adjust the VCTRUNK that is bound with VC-4.

Product

Fault Type

Configuration_Problem

Symptom

The 622 Mbit/s service fails to be created.

Cause Analysis

The four bound VC4 virtual connections are in the first ATM processing unit. The source end or sink end of the created connection belong to the same external port. The bandwidth used at the source end and sink end is 622 Mbit/s x 2 = 1244 Mbit/s, which exceeds the maximum bandwidth of a single ATM processing unit.

Procedure

  1. Delete the VCTRUNK that is bound with VC4 timeslots 1 -4.
  2. Set up the VCTRUNK that is bound with VC4 timeslots 5 -8.

Reference Information

None.
