Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
Workaround: Reduce the number of applied class maps.
• CSCed76109
Symptoms: On a Cisco 7500 series that is equipped with Versatile Interface Processors (VIPs) with
ATM port adapters, the ATM PVCs may not come back up after the ATM interface flaps. This occurs
because the interfaces in the VIP do not transmit any packets but still process incoming traffic.
Conditions: This symptom is observed in a dLFIoATM environment in which distributed Class
Based Weighted Fair Queueing (dCBWFQ) is configured on PPPoATM virtual templates.
Workaround: Apply any kind of distributed queueing on any interface or subinterface of the affected
VIP. Doing so triggers all interfaces to start transmitting again, enabling the ATM PVCs to come
back up.

Symptoms: A CHOC12DS1 line card does not support a sufficient number of BERT patterns.
Conditions: This symptom is observed on a Cisco 12000 series.

Engine 2 interface and when the member interfaces in the bundle are toggled.
