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
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. |
All command modes.
This example displays the linktrace database information for MEP 59, for the MA index 1, for the myMD1 MD:
