HP Comware 5 Debug Manual Vol 3

# Enable MLD proxy packet debugging on the public network. When MLD proxy is enabled on the

interface, output similar to the following example is generated:

<Sysname> debugging mld proxying packet

*0.1726142 Sysname MLD/7/PRY_EVT: Received MLDv1 query for group FF0E::101:101 on version

1 proxying interface Ethernet1/1(FE80::200:6C00). (G362885)

// MLD received an MLDv1 query message for group FF0E::101:101 on the upstream interface Ethernet

1 / 1.

*0.1754567 Sysname MLD/7/PRY_EVT: MLDv1 report for group FF0E::101:101 sent out

Ethernet1/1(FE80::200:6C00). (G363449)

// After the entry for group FF0E::101:101 was added, the proxy device sent an MLD report for group

FF0E::101:101 on Ethernet 1/1.

*0.1752533 Sysname MLD/7/PRY_EVT: Type 3 record added for group FF0E::101:101. (G363564)

// When an MLD report was sent as a result of a change in the membership for the multicast group

F F 0 E : :101:101, a TO-IN group record for the group was added.

*0.1783136 Sysname MLD/7/PRY_EVT: Source 100::10 added to group record. (G363647)

// The source 100::10 was added into the group record.

*0.1790527 Sysname MLD/7/PRY_EVT: MLDv2 report sent. (G363662)

// When the membership for the group changed, an MLDv2 report was sent to the upstream device.

# Enable MLD proxy route debugging. When MLD proxy is enabled on the interface, output similar to

the following example is generated:

<Sysname> debugging mld proxying routing-table

*0.57932162 Sysname MLD/7/PRY_RT:(public net): Entry (100::1, FF3E::1) created in IPv6

multicast routing table. (G01597)

// MLD received an (S, G) join with the group address in the SSM group range on a downstream

interface and created a forwarding entry.

*0.58934175 Sysname MLD/7/PRY_RT:(public net): Entries for group FF3E::1 removed upon

change of SSM group range. (G36139)

// MLD detected a change in the SSM group policy and removed entries for the group FF3E: :1.

*0.59833187 Sysname MLD/7/PRY_RT: Loss of route for (100::1, FF3E::1) detected, (S,G) entry

removed. (G361460)

// MLD detected that the route was lost and removed the associated forwarding entry.

*0.58034165 Sysname MLD/7/PRY_RT:(public net): Recovery of route for (100::1, FF3E::1)

detected, (S,G) entry created. (G361460)

// MLD detected that the route was recovered and created the associated forwarding entry.
