Management and Configuration Guide K/KA/KB.15.15

buffer: Enables syslog logging to
send the debug message types
specified by the debug debug-type
command to a buffer in switch memory.
Sends standard Event Log messages to
configured debug destinations. (The
event
same messages are also sent to the
switch's Event Log, regardless of
whether you enable this option.)
fib: Displays IP Forwarding
Information Base messages and events.
ip
forwarding: Sends IPv4 forwarding
messages to the debug destinations.
ospf: Sends OSPF event logging to the
debug destinations.
ospfv3: Enables debug messages for
OSPFv3.
packet: Sends IPv4 packet messages
to the debug destinations.
pim [packet [filter source
ip-addr | vlan vid ]]
: Enables or disables tracing of PIM
messages.
Note: When PIM debugging is enabled,
the following message displays:
PIM Debugging can be
extremely CPU intensive when
run
on a device with an existing
high CPU load or on a switch
with more than 10 PIM-enabled
VLANs. In high load
situations, the switch may
suffer from protocol
starvation, high latency, or
even reload. When debugging
a switch with more than 10
PIM-enabled VLANs, the “vlan”
option in “debug ip pim
packet” should be utilized.
Debugging should only be used
temporarily while
troubleshooting problems.
Customers are advised to
exercise caution when running
this command in a highstress
production network.
pbr: Logs a message when a PBR policy
is applied, when the action in a class
goes active or when it goes inactive.
rip: Sends RIP event logging to the
debug destinations.
dhcpv6-client: Sends DHCPv6
client debug messages to the configured
debug destination.
ipv6
dhcpv6-relay: Sends DHCPv6 relay
debug messages to the configured
debug destination.
