Bandwidth Limiting
You can limit an application ’ s uplink or downlink bandwidth. This limit keeps the
traffic from using up too much of the out-going interface ’ s bandwidth. This way
you can make sure there is bandwidth for other applications. Use the following
guidelines:
• The sum of the bandwidth allotments that apply to the WAN interface (LAN to
WAN, WLAN to WAN) must be less than or equal to the Uplink value that you
configure in the Bandwidth Management General screen.
• The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN,
WAN to WLAN) must be less than or equal to the Downlink value that you
configure in the Bandwidth Management General screen.
16.2 General
Use this screen to enable bandwidth management and assign uplink/downlink
limits. You can use either one of the following types:
• Priority Queue . Enable bandwidth management to give uplink traffic that
matches a bandwidth rule priority over traffic that does not match a bandwidth
rule. (This type does not apply to downlink traffic.)
• Bandwidth Allocation . Enabling bandwidth management also allows you to
control the maximum or minimum amounts of bandwidth that can be used by
traffic that matches a bandwidth rule.
Note: You cannot apply both bandwidth management types at the same time.
