5
debug ipv6 pim nbr-change
Syntax: [no] debug ipv6 pim nbr-change [nbr_address]
The nbr_address variable specifies the neighbor address.
This command controls the IPv6 PIM neighbor changes and the command output resembles the
following example.
Brocade# debug ipv6 pim nbr-change
PIM6: nbr-change debugging is on

Syntax: [no] debug ipv6 pim packet source_address group_address [rate]
• source_address - Specifies the IPv6 source address of the PIM packet
• group_address - Specifies the IPv6 group address of the PIM packet.
• rate - Specifies the hardware rate.
This command displays debugging information about the IPv6 PIM packets. Command output
resembles the following example.
Brocade# debug ipv6 pim packet
