For rate reservations to be enforced, a rate limit must be set for the traffic type
that the reservation is made for. Setting a rate limit for a broader traffic type, of
which the one the reservation is made for is a subset, is also acceptable. For
example, when making a rate reservation for voice traffic from wlan1 to eth0
(‘out.eth0.wlan1.vo.reserve’), a limit must be set with ‘out.eth0.limit’,
‘out.eth0.wlan1.limit’, or ‘out.eth0.wlan1.vo.limit’.
Rate reservations guarantee bandwidth for a particular traffic type, but if no such traffic is
present, the bandwidth reserved will be returned to the pool of available bandwidth for other
traffic types to use. The points at which rate reservations can be made are shown in Figure 54.
These points are similar to where rate limits can be placed, except that rate reservations
require both an input and output interface, whereas rate limits can be made without specifying
an input interface.
Figure 54. Quality of Service rate reservation control points
All rate reservation parameter values are in kbps. If no rate reservation parameter is
set, rate reservation will be disabled for that interface or interface and traffic
combination.
A rate reservation, which guarantees a certain amount of bandwidth, can be made for traffic
that enters the EL-500 through a particular interface and exits it through another interface.
Rate reservations can also be set based on traffic type through an interface. The default value
set for the EL-500 rate reservation is applied to interfaces that have their bandwidth
reservation parameters set to ‘inherit’ or are left blank.
