[afnog] Dealing with nbar unknown traffic

[Benjamin Cobblah]

Dear All,

I have a cisco 2600 which per Nbar, i have about 85% of my bandwidth being consumed by unknown traffic. (very disturbing). Could anyone help me block this traffic immediately. I used the show ip nbar unclassified-port-stats and got thousands of both tcp and udp ports. Is there a smart way i can block this traffic without using thousands of access lists to block each port?

Thanks in advance

Benjamin
