Parameters
If you enable RSVP, you specify the following information:
■
Maximum total reservable bandwidth
■
Maximum per-reservation bandwidth
■
Policing option ( edge, always, or never, with edge as the default)
■
Service level for excess/policed traffic ( best or low , with low as the
default). This setting applies to the excess traffic with the reserved
bandwidth (that is, in which queue it should be placed).
After you enable RSVP, you can use your configuration tool (for example,
the Administration Console) to display summary or detail information
about RSVP. Figure 78 shows a sample RSVP detail display.
Figure 78 identifies the RSVP data flow as it passes through the Layer 3
module and provides the following information:
■
Session information, including destination IP addresses and ports,
protocols, sender, receivers, and RSVP reservations
■
Session sender information that identifies port numbers, source IP
addresses, previous hop addresses, Logical Interface Handle (LIH)
values, Time To Die (TTD) values, bandwidth values, burst size values,
and output ports
■
Session receiver and reservation information that identifies port
numbers, an RSVP style (ST) of fixed filter (FF), shared explicit (SE), or
wildcard filter (WF), next-hop addresses, LIH values, TTD, values,
bandwidth values, burst size values, and filters
■
The actual flow that is installed on the system (shown in the last
portion of the display)
