Source IP
Address
Enter the IP address of source that meats this class. Note that for traffic from 'LAN to
WAN', since BWM is before NAT, you should use the IP address before NAT
processing.
Source Subnet
Mask
Enter the destination subnet mask.
Source Port
Enter the source port number of the traffic.
Protocol ID
Enter the protocol number for the traffic. 1 for ICMP, 6 for TCP or 17 for UDP
After configuration BWM, you can check current bandwidth of the configured traffic in
ADVANCED->BWM MGMT->Monitor. The values in the column of Current usage (kbps) would
display the actually number.
Scenario - Limit bandwidth usage, but when there is residual bandwidth, we hope it can be shared fairly
among several active traffic.
Description
FTP Client A can get 400kbps FTP traffic and FTP Client B can get 800 kbps FTP traffic and IPTV user
can retrieve 800 kbps UDP streaming.
LAN Interface: Fairness-based, Speed = 2048kbps
Class 1: Budget = 400kbps, Dest. IP = FTP Client A’s IP, Service = FTP, Priority = 3, enable Borrow
Class 2: Budget = 800kbps, Dest. IP = FTP Client B’s IP, Service = FTP, Priority = 3, enable Borrow
Class 3: Budget = 800kbps, Dest IP = IPTV Client’s IP, Protocol = UDP.
