HP Comware 5 Debug Manual Vol 3

Examples
A multicast tunnel interface (MTI) is a global interface. Unless otherwise stated, all examples in this
section are based on centralized devices.
# Enable multicast tunnel error debugging. Output similar to the following example is generated when
an IPv4 packet of another multicast tunnel is sent under the following conditions:
•
A multicast tunnel is created between two PE devices.
•
The tunnel parameters are configured at both ends to bring the tunnel interface up.
<Sysname> debugging mtunnel error
*Jan 23 16:30:17:06 2007 Sysname MTUNNEL/7/debug:
mtunnel_error: Can't get MTunnel PhyInfo Ptr.
// The multicast tunnel failed to obtain the physical statistics data block of the multicast tunnel interface.
# Enable multicast tunnel event debugging. Output similar to the following example is generated when
a multicast tunnel is removed under the following conditions:
•
The multicast tunnel is created between two PE devices
•
Interrupts fail to be disabled when the multicast tunnel is removed.
<Sysname> debugging mtunnel event
*Jan 23 16:30:17:06 2007 Sysname MTUNNEL/7/debug:
mtunnel_event: SplImp is failed..
// The multicast tunnel failed to disable interrupts.
# Enable multicast tunnel management debugging. Output similar to the following example is generated
under the following conditions:
•
A multicast tunnel interface is created.
•
The multicast tunnel group address is set to 235.0.0.1.
<Sysname> debugging mtunnel management
*Jan 23 15:52:15:02 2007 Sysname MTUNNEL/7/debug:
mtunnel_management: Set MTunnel group addr=235.0.0.1.
// The multicast tunnel set the multicast tunnel interface group address to 235.0.0.1.
*Jan 23 15:52:15:02 2007 Sysname MTUNNEL/7/debug:
mtunnel_management: Set MTunnel Src addr=11.11.11.11.
// The multicast tunnel set the multicast tunnel interface source address to 11.11.11.11.
*Jan 23 15:52:55:18 2007 DUT1 MTUNNEL/7/debug:
mtunnel_management: The MTunnel has been UP, no change.
// The link state of the multicast tunnel interface was up without any change.
# Enable multicast tunnel packet debugging. Output similar to the following example is generated under
the following conditions:
•
A multicast tunnel interface is created, with the default group address 235.0.0.1 and the source
a d d r e s s 11.11.11.11.
•
The MD is configured.
•
The MD protocol is enabled to start protocol packet exchange.
<Sysname> debugging mtunnel packet
*Jan 23 15:52:15:02 2007 Sysname MTUNNEL/7/debug:
mgre_encapsulate: Payload is IP data.
// The packet that entered the multicast tunnel is an IP packet.
