HP Comware 5 Debug Manual Vol 3

// After MTI got up, an up event was received. BGP was informed to add local MDT routing information.
*Jun 16 08:21:50:706 2008 Sysname MD/7/MD:(mvpn): Send Join Group 225.1.2.3 to PD for
InstanceID 1(M04882)
*Jun 16 08:21:50:706 2008 Sysname MD/7/MD:(mvpn): Socket initialization is successful for
MTunnel0(12.34.56.78)(M04661)
*Jun 16 08:21:50:707 2008 Sysname MD/7/MD:(mvpn): PIM Initialization on MTI is done
successfuly for Instance 1(M04922)
// PIM-enabled interfaces exist in the VPN instance. The VPN instance sent a join notification to the
public network for joining the share-group, and the same PIM mode was initialized on all the MTI
interfaces.
# Enable MD packet debugging for VPN instance mvpn. When a remote PE device initiates an MDT
switchover, output similar to the following example is generated:
<Sysname> debugging md vpn-instance mvpn packet
*Mar 12 17:28:21:709 2007 Sysname MD/7/MD:(mvpn): Number of MD TLV received is 1(M03197)
*Mar 12 17:28:21:814 2007 Sysname MD/7/MD:(mvpn): (10.21.21.3, 235.4.5.6) entry exists
in the PIM MRT (M03443)
*Mar 12 17:28:21:953 2007 Sysname MD/7/MD:(mvpn): Refresh Time for 226.4.5.0 switch group
& sender 22.22.22.22(M03562)
*Mar 12 17:28:22:103 2007 Sysname MD/7/MD:(mvpn): Switch message processed
successfully(M03644)
// MD received a MDT switching notification message from a remote PE. The locally attached PE
received the packet (10.21.21.3, 235.4.5.6), and the local device refreshed the switching receiving timer.
# Enable MD timer debugging for VPN instance mvpn. When the MTI address query timer expires,
output similar to the following example is generated:
<Sysname> debugging md vpn-instance mvpn timer
*Mar 12 17:29:50:428 2007 Sysname MD/7/MD:Query-MTI-Address timer expires(M042864)
*Mar 12 17:29:50:524 2007 Sysname MD/7/MD:Result: 0, BGP Addr: 11.11.11.11(M042881)
*Mar 12 17:29:55:428 2007 Sysname MD/7/MD:Query-MTI-Address timer expires(M042864)
*Mar 12 17:29:55:524 2007 Sysname MD/7/MD:Result: 0, BGP Addr: 11.11.11.11(M042881)
// When the MTI address query timer (set to 5 seconds) expired, the MTI address was automatically
refreshed to keep consistent with the obtained BGP address.
