Creating an MD
Context
no-md-name: The MAID field in outgoing CCMs does not carry the MD name.
dns-md-format-name: The MD information in the MAID of outgoing CCMs is a character string obtained from the DNS text.
mac-md-format-name: The MD information in the MAID of outgoing CCMs consists of 6-byte MAC address plus two-byte integer in the range of 0 to 65535.
string: The MD information in the MAID of outgoing CCMs is a character string.
Perform the following operations on the device where Ethernet CFM needs to be configured.
Procedure
- Run system-view
The system view is displayed.
- Run cfm md md-name [ format { no-md-name | dns dns-md-format-name | mac-address mac-md-format-name | string string-md-format-name } ] [ level level ]
An MD is created and the MD view is displayed.
By default, an MD is at level 0. Level 0 is the lowest level.
Only IEEE Standard 802.1ag-2007 supports format, no-md-name, dns dns-md-format-name, mac-address mac-md-format-name, and string string-md-format-name.
To create multiple MDs, repeat step 2.
802.1ag packets from a lower-level MD are discarded when being transmitted through a higher-level MD, and 802.1ag packets sent to the MD of the same level are discarded or terminated. 802.1ag packets from a higher-level MD can be transmitted through a lower-level MD.
