Switch Management Commands 2077
User Guidelines
Debug output should be enabled with caution. Switch behavior may be
adversely affected by the additional processing load incurred from enabling
debug.
Example
console#debug ip dvmrp packet
debug ip igmp
Use the debug ip igmp command to trace IGMP packet reception and
transmission. The receive option traces only received IGMP packets and the
transmit option traces only transmitted IGMP packets. When neither
keyword is used in the command, then all IGMP packet traces are dumped.
Vital information such as source address, destination address, control packet
type, packet length, and the interface on which the packet is received or
transmitted is displayed on the console. Use the “no” form of this command
to disable IGMP traces.
Syntax
debug ip igmp packet [receive | transmit]
no debug ip igmp packet [receive | transmit]
Default Configuration
Display of IGMP traces is disabled by default.
Command Mode
Privileged Exec mode.
