OSPF LSA Issue ICX7150

Model - ICX7150-C12-2X10GR

Version - 08.0.95rT213

Each time a single port withing a vlan changes operational state, the VE initiates an LSA removal form the tree at the same time that it adds the LSA to the tree. This happens simultaneously and if there is an interface flapping due to a damaged cable, it creates excessive LSA churn that create random pauses in traffic.

Hey Vladimir,

Is the VE flapping during this event? This issue is probably best tracked via an official case (see my signature).

VE is stable during this event.

Now we have only Warranty for hardware replacement.

Could you share config if possible? If you are willing, it may be worth testing 10010g_cd8. Note: Many changes between 8.x and 10.x, so proceed with caution.
