Related Commands

show cam

show cam notification

To display the status of CAM table notifications, notification intervals, MAC addresses added and deleted, and MAC move counters statistics, use the show cam notification command.

show cam notification {all | counters | enable | historysize | interval | move | threshold | mod/port}

show cam notification history [{[-]number_of_log_entries}]

show cam notification move counters [vlan]

Syntax Description

all	Displays the CAM notification counters, enable, interval, and historysize information.
counters	Displays CAM notification counter information.
enable	Displays CAM notification feature information.
historysize	Displays the size of the CAM notification log.
interval	Displays the CAM notification interval.
move	Displays MAC move notification status.
threshold	Displays CAM usage monitoring status and parameters.
mod/port	Number of the module and port.
history	Displays CAM notification history logs.
-	(Optional) Specifies the most recent log entries.
number_of_log_entries	(Optional) Number of the CAM notification log entries to display; if a CAM notification log number is not specified, the entire log is displayed.
move counters	Displays MAC move statistics.
vlan	(Optional) Number of the VLAN; valid values are from 1 to 4094.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

The MAC move counter records a maximum of 1000 MAC moves per VLAN only. Once this maximum has been exceeded, new moves are not recorded on the VLAN. You can enter the clear cam notification move counters command to clear the counters.

Due to differences between the CPU and the ASIC processing speed differences, the number of moves reported by the MAC move counter may differ from the actual number of MAC moves.

MAC move counter notification is not supported on EARL 4 and earlier.

show cdp

To display Cisco Discovery Protocol (CDP) information, use the show cdp command.

show cdp

show cdp neighbors [mod[/port]] [vlan | duplex | capabilities | detail]

show cdp neighbors exclude ip-phone

show cdp port [mod[/port]]

Syntax Description

neighbors	Shows CDP information for Cisco products connected to the switch.
[mod[/port]]	(Optional) Number of the module for which CDP information is displayed and optionally, the number of the port for which CDP information is displayed.
vlan	(Optional) Shows the native VLAN number for the neighboring Cisco products.
duplex	(Optional) Shows the duplex type of the neighboring Cisco products.
capabilities	(Optional) Shows the capability codes for the neighboring Cisco products; valid values are R, T, B, S, H, I, and r (R = Router, T = Trans Bridge, B = Source Route Bridge, S = Switch, H = Host, I = IGMP, and r = Repeater).
detail	(Optional) Shows detailed information about neighboring Cisco products.
exclude ip-phone	Excludes IP phone information from the display of neighboring Cisco products.
port	Shows CDP port settings.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

The per-port output of the show cdp port command is not displayed if you globally disable CDP. If you globally enable CDP, the per-port status is displayed.

If you enter the show cdp neighbors command for a device that supports earlier versions of CDP, "unknown" is displayed in the VTP Management Domain, Native VLAN, and Duplex fields.
