QoS - RSVP bandwidth and flow reservations
In its most basic form, this command specifies two values:
- The maximum amount of bandwidth, in kb/s, that can be allocated by RSVP flows. The range is from 1 to 10000000.
- The maximum amount of bandwidth, in kb/s, that may be allocated to a single flow. The range is from 1 to 10000000.
An example of the command on a particular interface is as follows:
Router(config-if)#ip rsvp bandwidth 256 64
This command reserves a total of 256 kb/s for all RSVP flows, and reserves a maximum of 64 kb/s for each individual flow.
Thus, this interface can support RSVP flows of up to 64 kb/s each, and can support a total flow bandwidth of 256 kb/s.
That means that the interface can support four flows of 64 kb/s each, or eight flows of 32 kb/s each or a combination of two flows of 64 kb/s each and four flows of 32 kb/s each, and so on. As long as the total bandwidth of all the flows does not surpass 256 kb/s.
Any attempts at creating individual flows larger than 64 kb/s or creating a number of flows that will surpass a total of 256 kb/s will fail.
