Network requirements
BitTorrent (BT) is a kind of shared software for file download. Its feature is as
follows: The more people are using it to download a file, the faster the file
downloads. While BT download greatly reduces the burden of the download
server, it also brings dramatic increase of download traffic on the internet. As a
result, the network bandwidth is greatly occupied by the BT download traffic,
which influences other network services seriously. Therefore, it is necessary to
control the BT traffic effectively.
The purpose of the configuration is to prohibit the BT data traffic passing through
port GE7/1/8 by configuring proper ACL rules.
CAUTION: 3C17526 series cards do not support BT traffic control configuration.
