Ip path excessive packet loss rate

  1. 1. ALM-25898 IP Path Excessive Packet Loss Rate Description This alarm is reported when the average packet loss rate is higher than the preset alarm threshold during 10 minutes, in the case that the IP PM function is activated on the uplink of the IP path. Parameters Parameter Name Parameter Description Cabinet No. Cabinet number of the faulty board Subrack No. Subrack number of the faulty board Slot No. Slot number of the faulty board IP Path No. IP path number Packet Loss Rate (per mill) Packet loss rate of the IP path Description Peer description information Impact on the System Alarm Severity Alarm Impact Minor The data packet on the link between the NE and the RNC is discarded, and the services carried on this IP path cannot be performed normally. System Actions None Possible Causes • The bandwidth configuration of the IP path on the NE side is inconsistent with that on the RNC side. • The bit error rate (BER) or frame error rate (FER) of the link bearing the IP path is extremely high. • The bandwidth of the physical link between the NE and the RNC is restricted. Procedure 1. Check that the bandwidth of the IP path is configured correctly. a. Run the MML command LST IPPATH to check whether the receive bandwidth and transmit bandwidth of the IP path are consistent with those configured on the RNC . Y=> The parameter settings are consistent. Go to step 2. N => The parameter settings are inconsistent. Go to sub-step b. b. Reconfigure the receive bandwidth and transmit bandwidth of the IP path to keep them consistent with those configured on the RNC. Wait for 10 minutes. Check whether the alarm is cleared. Y => The alarm is cleared. No further action is required. N => The alarm is not cleared. Go to step 2. 2. Check for the correlated alarm of the link bearing the IP path on the M2000. a. On the M2000, check for the correlated alarm of the link bearing the IP path: Ethernet-correlated alarms PPP/MLPPP-correlated alarms Y => The correlated alarm exists. Go to sub-step b. N => The correlated alarm does not exist. Go to step 3. b. Clear the correlated alarm with recommended actions. Check whether the alarm is cleared. Y => The alarm is cleared. No further action is required. N => The alarm is not cleared. Go to step 3. 3. Check the bandwidth of the physical link between the NE and the RNC. a. Contact the network plan engineers to check whether the configured bandwidth of the link between the RNC and the NE meets the service requirements. If the configured bandwidth cannot meet the service requirements, the network replan is required. b. Increase the link bandwidth according to the network replan. Check whether the alarm is cleared. Y => The alarm is cleared. No further action is required. N => The alarm is not cleared. Contact Huawei Customer Service Center.
