| RFO Ziggo Lite |
Datum RFO: 28-12-2020 Datum incident: 24-12-2020 Status RFO: Preliminary Overview: At 11:03 a spike in network traffic was seen on one Ziggo - Comsave NNI. The edge device which facilitates this NNI saw traffic increase restricted to this port. The normal traffic flowing on this port was impacted by this rise in traffic which caused a major network outage on all Ziggo services flowng through the NNI. After analysis this traffic was found to be coming only from Ziggo services and contact was made with the Ziggo NOC for assistance. The Ziggo NOC gave a preliminary response reporting a possible loop in the network and further investigation was needed. The Ziggo NOC advised that they saw a single MAC address on 2 customer VLAN's. No other issues were detected. The Ziggo NOC advised that they did not see the same port telemetry we were seeing. The data sent over the NNI was not visible on the Ziggo side according to the Ziggo NOC. The VLAN's were rejected on the edge device. After the VLAN configuratie was implemented traffic flow returned to expected levels. Preliminary configuration was added to disallow the traffic seen during the incident. So far the root cause for the traffic increase has not been found. The setup and conditions are being rebuilt in a lab environment to analyse the situation in depth. 1) The exact reason for the outage (why did it happen?) This will be shared at a later date. Investigation is still ongoing. 2) On what device was the issue The Comsave edge device connected to the Ziggo edge device. 3) The location (geographical location or network location i.e. core-/access-network or last mile) or exchange names of the trouble point? Amsterdam 4) Who solved it Ziggo and Comsave NOC 5) What was done to solve it Removal of VLAN interfaces 6) Is this fix permanent? Please refer to point 1. 7) Are there any measures taken to prevent this from occurring? Please refer to point 1. Monitoring has been set up to alert the NOC when the first indicators of this behavior occurs. Configuration changes have been made to further disallow traffic seen during the incident. |
