Use this command to display linktrace database information for all or the specified end-point.

show cfm md {string-name name | dns-like-name dns-name | mac-int-name mac-name | no-name | index index} ma {string-name name | vid-name vlan | id-name id | index index} mep [mep-id mep-id] linktrace

Parameters

md Specifies an MD context.
ma Specifies an MA context.
mep Specifies a maintenance end-point context.
string-name name Specifies the MD or association string name of the linktrace database information to display. Valid values are up to 43 printable characters.
dns-like-name dns-name Specifies the MD DNS like string name of the linktrace database information to display. Valid values are up to 43 printable characters.
mac-int-name mac-name Specifies the MD MAC address formatted string name of the linktrace database information to display. A valid value is a MAC address formatted string plus an integer index ID value separated by a period (.) in the format xx-xx-xx-xx-xx-xx.ID or xx:xx:xx:xx:xx:xx.ID, where x is a hex value and the ID range is 0 - 65535.
no-name Specifies the NULL string named MD of the linktrace database information to display.
index index Specifies the MD index value or the MA index of the linktrace database information to display.
vid-name vlan Specifies the MA VLAN ID name of the linktrace database information to display.
id-name id Specifies the MA ID name of the linktrace database information to display.
index index Specifies the MA index value of the linktrace database information to display.
mep-id mep-id (Optional) Specifies a MEP of the linktrace database information to display.

Defaults

  • If a MEP ID is not specified, information for all end-points is displayed.
  • If the -verbose option is not specified, a standard level of information is displayed that displays only the direct path between the originating MEP and the target maintenance point. If -verbose is specified, all paths linktrace discovered through the topology are displayed.

Mode

All command modes.

Examples

This example displays the linktrace database information for MEP 59, for the MA index 1, for the myMD1 MD:
