acc-qos
To generate an SNMP event if the quality of service for a dial peer drops below a specified level, use
the acc-qos dial-peer configuration command. Use the no form of this command to use the default
value for this feature.
acc-qos {best-effort | controlled-load | guaranteed-delay}
no acc-qos
Syntax Description
best-effort Indicates that Resource Reservation Protocol (RSVP) makes no
bandwidth reservation.
controlled-load Indicates that RSVP guarantees a single level of preferential service,
presumed to correlate to a delay boundary. The controlled load service
uses admission (or capacity) control to assure that preferential service is
received even when the bandwidth is overloaded.
guaranteed-delay Indicates that RSVP reserves bandwidth and guarantees a minimum bit
rate and preferential queuing if the bandwidth reserved is not exceeded.
Default
The default value is best-effort. Using the no form of this command is the same as the default.
Command Mode
Dial-peer configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.3(1)T.
Use the acc-qos dial-peer command to generate an SNMP event if the quality of service for specified
dial peer drops below the specified level. When a dial peer is used, the Cisco IOS software reserves
a certain amount of bandwidth so that the selected quality of service can be provided. Cisco IOS
software uses Resource Reservation Protocol (RSVP) to request quality of service guarantees from
the network.
To select the most appropriate value for this command, you need to be familiar with the amount of
traffic this connection supports and what kind of impact you are willing to have on it. The Cisco IOS
software generates a trap message when the bandwidth required to provide the selected quality of
service is not available.
This command is only applicable to VoIP peers.
