SonicOS Enhanced 4.0 Administrator Guide
The outbound SMTP traffic is guaranteed 20 percent of available bandwidth available to it and
can get as much as 40 percent of available bandwidth. If this is the only access rule using
bandwidth management, it has priority over all other access rules on the SonicWALL security
appliance. Other access rules use the remaining bandwidth (minus 20 percent of bandwidth, or
greater than minus 20 percent and less than minus 40 percent of bandwidth).
Note Note: Access rules using bandwidth management have a higher priority than access rules
not using bandwidth management. Access rules without bandwidth management are given
lowest priority.
Tip You must select Bandwidth Management on the WAN > Ethernet page. Click Network, then
Configure in the WAN line of the Interfaces table, and type your available bandwidth in the
Available WAN Bandwidth (Kbps) field.
