Quality of Service Commands: ip rsvp atm-peak-rate-limit Through ip rtp priority
This chapter explains the function and syntax of the quality of service commands from ip rsvp atm-peak-rate-limit through ip rtp priority. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Quality of Service Solutions Command Reference, Release 12.1.
To set a limit on the peak cell rate (PCR) of reservations for all newly created Resource Reservation Protocol (RSVP) switched virtual circuits (SVCs) established on the current interface or any of its subinterfaces, use the ip rsvp atm-peak-rate-limit interface configuration command. To remove the current peak rate limit, in which case the reservation peak rate is limited by the line rate, use the no form of this command.
ip rsvp atm-peak-rate-limit limit
no ip rsvp atm-peak-rate-limit
Syntax Description
limit
| The peak rate limit of the reservation specified in kilobytes. The minimum value allowed is 1 KB; the maximum value allowed is 2 GB.
|
To enable Resource Reservation Protocol (RSVP) for IP on an interface, use the ip rsvp bandwidth interface configuration command. To disable RSVP, use the no form of this command.
ip rsvp bandwidth [interface-kbps [single-flow-kbps]]
no ip rsvp bandwidth [interface-kbps [single-flow-kbps]]
Syntax Description
interface-kbps
| (Optional) Amount of bandwidth (in kbps) on interface to be reserved. The range is 1 to 10000000.
|
single-flow-kbps
| (Optional) Amount of bandwidth (in kbps) allocated to a single flow. The range is 1 to 10000000.
|
To configure an interface as a Designated Subnetwork Bandwidth Manager (DSBM) candidate, use the ip rsvp dsbm candidate interface configuration command. To disable DSBM on an interface, which exempts the interface as a DSBM candidate, use the no form of this command.
ip rsvp dsbm candidate [priority]
no ip rsvp dsbm candidate
Syntax Description
priority
| (Optional) A value in the range of 64 to 128. Among contenders for the DSBM, the interface with the highest priority number wins the DSBM election process.
|
To configure the NonResvSendLimit object parameters, use the ip rsvp dsbm non-resv-send-limit interface configuration command. To use the default NonResvSendLimit object parameters, use the no form of this command.

no ip rsvp dsbm non-resv-send-limit {rate kbps | burst kilobytes | peak kbps | min-unit bytes | max-unit bytes}
Syntax Description
rate kbps
| The average rate (in kilobytes per second) for the DSBM candidate.
|
burst kilobytes
| The maximum burst size (in kilobytes) for the DSBM candidate.
|
peak kbps
| The peak rate (in kilobytes per second) for the DSBM candidate.
|
min-unit bytes
| The minimum policed unit (in bytes) for the DSBM candidate.
|
max-unit bytes
| The maximum packet size (in bytes) for the DSBM candidate.
|
To enable Resource Reservation Protocol (RSVP) to attach itself to NetFlow so that it can leverage NetFlow services to obtain flow classification information about packets in order to update its token bucket and set IP Precedence as required, use the ip rsvp flow-assist interface configuration command. To detach RSVP from NetFlow, use the no form of this command.
ip rsvp flow-assist
no ip rsvp flow-assist
Syntax Description
This command has no arguments or keywords.
To enable neighbors to request a reservation, use the ip rsvp neighbor interface configuration command. To disable this feature, use the no form of this command.

|
To enable the router to mark the IP Precedence value of the type of service (ToS) byte for packets in a Resource Reservation Protocol (RSVP) reserved path using the specified values for packets that either conform to or exceed the RSVP flowspec, use the ip rsvp precedence interface configuration command. To remove existing IP Precedence settings, use the no form of this command; if neither conform nor exceed is specified, all IP Precedence settings are removed.
ip rsvp precedence {[conform precedence-value] [exceed precedence-value]}
no ip rsvp precedence [conform] [exceed]
Syntax Description
conform precedence-value
| Specifies an IP Precedence value in the range of 0 through 7 for traffic that conforms to the RSVP flowspec. The IP Precedence value is written to the three high-order bits (bits 5 through 7) of the ToS byte of a packet's IP header. Either conform or exceed is required; both keywords may be specified.
When used with the no form of the command, this keyword is optional.
|
exceed precedence-value
| Specifies an IP Precedence value in the range of 0 through 7 for traffic that exceeds the RSVP flowspec. The IP Precedence value is written to the three high-order bits (bits 5 through 7) of the ToS byte of a packet's IP header. Either conform or exceed is required; both keywords may be specified.
When used with the no form of the command, this keyword is optional.
