Debug Types
This section describes the types of debug messages the switch can send to
configured debug destinations.
Syntax: [no] debug < debug-type >
all
Configures the switch to send all debug types to the config-
ured debug destination(s). (Default: Disabled)
event
Configures the switch to send Event Log messages to the
configured debug destination(s). Note: This has no effect
on event notification messages the switch routinely sends
to the Event Log itself. Also, this debug type is automatically
enabled in these cases:
• If there is currently no Syslog server address configured
and you use logging < ip-addr > to configure an address.
• If there is currently at least one Syslog server address
configured and the switch is rebooted or reset.
(Default: Disabled)
dhcp-snooping
Assigns DHCP snooping debug messages to the debug des-
tination
lldp
Assigns LLDP debug messages to the debug destination.
