== Troubleshooting MGCP ==

To provide information about the operation of the MGCP application, use the following commands in privileged EXEC mode:

{| border = 1
|-
!Command
!Purpose
|-
|
Router# debug mgcp all
|

Displays real-time information about MGCP errors, events, media, packets, parser, system resource check (SRC), and VoIP call admission control (CAC)
|-
|
Router# debug mgcp errors {endpoint endpoint-name}
|

Displays MGCP errors
|-
|
Router# debug mgcp events {endpoint endpoint-name}
|

Displays MGCP events
|-
|
Router# debug mgcp media {endpoint endpoint-name}
|

|-
|
Router# debug mgcp packets {endpoint endpoint-name | input-hex}
|

Displays MGCP packet information, with input packets optionally in hexadecimal format
|-
|
Router# debug mgcp parser
|

|-
|
Router# debug mgcp src
|

Displays MGCP SRC CAC information
|-
|
Router# debug mgcp voipcac
|

Turns on debugging messages for the VoIP CAC process at the MGCP application layer
|}

== Troubleshooting MGCP SRC CAC ==

To help identify SRC CAC problems, use the following commands in privileged EXEC mode:

{| border = 1
|-
!Command
!Purpose
|-
|
Router# show call threshold {status [unavailable] | stats}
|

Displays status of configured triggers or statistics for application programming interface (API) calls that were made to global and interface resources
|-
|
Router# show mgcp statistics
|

|-
|
Router# debug call threshold
|

Displays details of trigger actions
|-
|
Router# debug mgcp src
|

Provides debug information for MGCP SRC CAC calls
|}

== Troubleshooting MGCP RSVP CAC ==

To identify and trace RSVP CAC problems, use the following commands in privileged EXEC mode:

{| border = 1
|-
!Command
!Purpose
|-
|
Router# show call fallback cache
|

Displays a network congestion level check result if one has been cached
|-
|
Router# show call rsvp-sync stats
|

Displays statistics for calls that attempted RSVP reservation
|-
|
Router# show call rsvp-sync conf
|

Displays the configuration settings for RSVP synchronization
|-
|
Router# show ip rsvp reservation
|

Displays the RSVP-related receiver information currently in the database
|-
|
Router# debug call rsvp-sync func-trace
|

|-
|
Router# debug call rsvp-sync events
|

Displays events that occur during RSVP setup
|-
|
Router# debug ip rsvp detail
|

|}

== Troubleshooting MGCP SA Agent CAC ==

To help identify Service Assurance (SA) Agent CAC problems, use the following commands in privileged EXEC mode:

{| border = 1
|-
!Command
!Purpose
|-
|
Router# show call fallback cache
|

Displays a network congestion level check result if one has been cached
|-
|
Router# debug call fallback probes
|

Verifies that probes are being sent correctly
|-
|
Router# debug call fallback detail
|

Displays details of the VoIP call fallback
|-
|
Router# show rtr application {tabular | full}
|

|-
|
Router# debug rtr error
|

Enables logging of SA agent run-time errors
|-
|
Router# debug rtr trace
|

Traces the execution of an SA agent operation
