Cisco Cisco IOS Software Release 12.4(4)T 發佈版本通知

Further Problem Description: When the connected DSLAM is configured to mark some or all 
packets that are larger than 1400 bytes with the CNG bit (indicating a possible congestion), the 
Cisco 870 should not mark these packets as errors and should not drop these packets but should 
increase the congestion counters and process the packets normally if sufficient bandwidth is 
available.
