acl
|
When a match occurs on an ACL "deny" ACE (with log configured), the switch sends an ACL message to configured debug destinations. For information on ACLs, see the "Access Control Lists (ACLs)" in the latest version of the following guides:
NOTE: ACE matches (hits) for permit and deny entries can be tracked using the
show statistics <aclv4|aclv6> command.
(Default: Disabled—ACL messages for traffic that matches "deny" entries are not sent.)
|
all
|
Configures the switch to send all debug message types to configured debug destinations.(Default: Disabled—No debug messages are sent.)
|
cdp |
Sends CDP information to configured debug destinations.
|
destination |
logging—Disables or re-enables syslog logging on one or more syslog servers configured with the
logging <syslog-ip-addr>
command.session—Assigns or re-assigns destination status to the terminal device that was most recently used to request debug output.buffer—Enables syslog logging to send the debug message types specified by the
debug <debug-type>
command to a buffer in switch memory.For more information on these options, see
Debug destinations.
|
event
|
Configures the switch to send Event Log messages to configured debug destinations.
NOTE: This value does not affect the reception of event notification messages in the Event Log on the switch.
Event Log messages are automatically enabled to be sent to debug destinations in these conditions:
If no syslog server address is configured and you enter the
logging <syslog-ip-addr>
command to configure a destination address.
If at least one syslog server address is configured in the startup configuration, and the switch is rebooted or reset.
Event log messages are the default type of debug message sent to configured debug destinations.
|
ip [fib | forwarding | packet | rip]
|
Sends IP messages to configured destinations.
|
| |
ip [fib [events]] |
For the configured debug destinations:events—Sends IP forwarding information base events.
|
| |
ip [packet]
|
Enables the specified PIM message type.
|
| |
ip [rip [database | event | trigger]]
|
rip {<database | event | trigger>} —Enables the specified RIP message type for the configured destination(s).
database—Displays database changes.
event—Displays RIP events.
trigger—Displays trigger messages.
|
ipv6 [dhcpv6-client | nd | packet]
|
NOTE: See the "IPv6 Diagnostic and Troubleshooting" in the
IPv6 configuration guide for your switch for more detailed IPv6 debug options.
When no debug options are included, displays debug messages for all IPv6 debug options.
dhcpv6-client [events | packet]—Displays DHCPv6 client event and packet data.nd—Displays debug messages for IPv6 neighbor discovery.packet—Displays IPv6 packet messages.
|

Enables all LLDP message types for the configured destinations.
|
security [arp-protect | dhcp-snooping | dynamic-ip-lockdown | port-access | port-security | radius-server | ssh | tacacs-server | user-profile-mib] |

The levels are fatal, error, info, verbose, debug, debug2, and debug3.tacacs-server—Sends TACACS debug messages to the debug destination.user-profile-mib—Sends user profile MIB debug messages to the debug destination.
