When using ip rsvp bandwidthCommand, under default configuration (interface-kbps and single-
flow-kbp), the max resource reservation for the whole port and resource reservation for single data
process will be limited to just 75% of the port total resource.
62.3.2 Start RSVP in an IP Phone Module Configuration
Before configuring our IP Phone and IP Phone module of the router to use Voice over IP, users have to enable
RSVP to use RSVP to reserve resource.
RSVP Command has to be configured on ports that requires RSVP. That is because RSVP is disable by default.
(See the last chapter)
IP phone disables QoS (default), therefore, users must configure dial-peer voipCommand with enabling
QoSCommand.
To enable RSVP on interface f0/0, use the following commands in dail-peer Configuration mode of none IVR
type:
Command Function
req-qos
{
best-effort
|
controlled-load
|
guaranteed-delay
}
Used Qos policy in dialpeer.
62.3.3 Use RSVP to Configure Command
In this RSVP, users may use Command provided by the module to adjust RSVP. Adjustments including
establishing RSVP conversation, RSVP path, path tear, resv, resv tear message transmission. This is going to
be useful for users to test RSVP.
Users may use the following Commands in global configuration mode:
Command Function
ip rsvp local session
session-ip-address
session-dport {tcp | udp}
By setting this Command, users may configure a
new RSVP dialog, which can be used by other
Commands.
ip rsvp local sender
session-id sender-ip-
address sender-sport [bandwidth] [burst-size]
Users may send path message with this
Command, whose no form may send path tear
message.
ip rsvp local reservation
session-id sender-
ip-address sender-sport [
guarantee
|
load
]
[bandwidth] [burst-size]
Users may send resv message with this
Command, whose no form may send resv tear
message.
62.3.4 Configure TOS and Precedence for RSVP flow
To obtain better reservation results, users may use Commands offered by RSVP module to
configure TOS and Precedence for RSVP. When RSVP flow is over the reserved range, the
Command configures a higher TOS. When RSVP flow is within the reserved range, the command
configures a lower TOS. So does Precedence.
Users may use the following Command in interface configuration mode:
Command Function
ip rsvp tos
{
conform
|
exceed
} tos-value This Command can be used to configure the reserved
TOS options.
ip rsvp precedence
{
conform
|
exceed
}
precedence-value
This Command can be used to configure the reserved
precedence options.
