Table 3-3
Debug Command
Description
OSPF
debug ip ospf adj
Provides OSPF adjacency events
debug ip ospf events
Provides OSPF event information
debug ip ospf packet
Provides OSPF packet information
debug ip ospf spf
Provides OSPF Shortest Path First algorithm information
debug ip ospf tree
Provides OSPF database tree information
EIGRP
debug ip eigrp neighbors
Provides EIGRP neighbor information
debug ip eigrp packets
Provides EIGRP packet information
debug ip eigrp transmit
Provides EIGRP transmission events
RIP
debug ip rip database
Provides RIP database event information
debug ip rip events
Provides RIP protocol events
debug ip rip trigger
Provides RIP triggered packet events
Use the
show debug
command to verify the enabled debugging options, as shown in Example
3-17. This example shows debugging enabled for Internet Control Message Protocol (ICMP)
packets. OSPF intra-area, interarea, and external events debugging are also enabled. RIP
protocol and Frame Relay event debugging are also enabled.
Example 3-17
show debug
Command Displays All Active Debugging
R2#show debug
Generic IP:
ICMP packet debugging is on
IP routing:
OSPF spf intra events debugging is on
OSPF spf inter events debugging is on
OSPF spf external events debugging is on
RIP protocol debugging is on
Frame Relay:
Frame Relay events debugging is on
Use the
undebug all
command to disable all debugging, as shown in Example 3-18. All
possible debugging is disabled.
