SonicWALL TZ 190 Manuale Utente

Once one or both BWM settings are enabled on the WAN interface and the available bandwidth 
has been declared, a Ethernet BWM tab will appear on Access Rules. The Bandwidth tab will 
present either Inbound settings, Outbound settings, or both, depending on what was enabled 
on the WAN interface:

The configuration on the General tab will classify the traffic. In the above example, which 
assumes no other configured BWM rules, traffic from the LAN (Trusted) Zone’s LAN Subnets 
destined to the VPN (Encrypted) Zone’s 10.50.165.0 remote subnet, consisting of Service 
Group VOIP will be guaranteed 30% of the declared bandwidth (30% of 1500Kbps = 450Kbps), 
but it will not be permitted to exceed 80% (80% of 1500Kbps = 1200Kbps), leaving 300Kbps for 
other traffic.

Bandwidth Management rules each consume memory for packet queuing, so the number of 
allowed queued packets and rules on SonicOS Enhanced is limited by platform (values are 
subject to change):

Consider the following about bandwidth management:

The grand total of all declared Guaranteed Bandwidth percentages across all BWM rules 
cannot exceed 100%, since it is not possible to guarantee greater than 100% of the 
available bandwidth.

The grand total of all Maximum Bandwidth values must be equal to or greater than the total 
Guaranteed Bandwidth.

The grand total of all Maximum Bandwidth values may exceed 100% (e.g. every BWM rule 
may specify 100% Maximum Bandwidth, if no explicit throttling is required).
