To disable a debug command use the no form of the command or use the no debug all command to turn off all debugging. debug cdp {all | errors | events {mts | packets | pss}} [interface {gigabitethernet slot/port | mgmt 0}] no debug cdp {all | errors | events {mts | packets | pss}} [interface {gigabitethernet slot/port | mgmt 0}] Syntax Description all errors events mts packets pss interface gigbitethernet slot/port mgmt 0 Enables debugging for all CDP features. Enables debugging for CDP error conditions. Enables debugging for CDP events. Enables debugging for CDP tx/rx MTS packets. Enables debugging for CDP tx/rx CDP packets. Enables debugging for all PSS related CDP events. (Optional) Specifies debugging for the specified interface. Specifies the Gigabit Ethernet interface slot and port. Specifies the management interface. Defaults Disabled. Command Modes EXEC mode. Command History Release 1.1(1) Modification This command was introduced. Usage Guidelines None. Examples The following example displays the system output when the debug cdp events packets command is issued: switch# debug cdp events packets Apr 8 21:22:34 cdp: Sent CDP packet, interface 0x2380000 Apr 8 21:22:34 cdp: Sent CDP packet, interface 0x2381000 Apr 8 21:22:35 cdp: Sent CDP packet, interface 0x2382000 Apr 8 21:22:35 cdp: Sent CDP packet, interface 0x2383000 Apr 8 21:22:51 cdp: Received CDP packet, interface 0x5000000 Apr 8 21:23:01 cdp: Sent CDP packet, interface 0x5000000 Apr 8 21:23:34 cdp: Sent CDP packet, interface 0x2380000 Apr 8 21:23:34 cdp: Sent CDP packet, interface 0x2381000 OL-18089-01, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family Command Reference 6-11
