Sender ID TLV

You can configure Junos OS to send the sender ID TLV along with the packets. The sender ID TLV is an optional TLV that is sent in continuity check messages (CCMs), loopback messages, and Link Trace Messages (LTMs), as specified in the IEEE 802.1ag standard. The sender ID TLV contains the chassis ID, which is the unique, CFM-based MAC address of the device, and the management IP address, which is an IPv4 or an IPv6 address. You can enable Junos OS to send the sender ID TLV at the global level by using the set protocols oam ethernet connectivity-fault-management sendid-tlv and the set protocols oam ethernet connectivity-fault-management sendid-tlv sendId_chassis_tlv commands. If the sender ID TLV is configured at the global level, then the default maintenance domain, maintenance association, and the maintenance association intermediate point (MIP) half function inherit this configuration.
You can also configure the sender ID TLV at the following hierarchy levels:

• Maintenance domain-At the [edit protocols oam ethernet connectivity-fault-management maintenance-domain maintenance-domain-name mip-half-function default] hierarchy level. Configuration performed at this level applies to all the maintenance associations under the maintenance domain.
• Default maintenance domain and the MIP half function-At the [edit protocols oam ethernet connectivity-fault-management maintenance-domain default-maintenance-domain-name mip-half-function default] hierarchy level.
• Maintenance association-At the [edit protocols oam ethernet connectivity-fault-management maintenance-domain maintenance-domain-name maintenance-association maintenance-association-name continuity-check] hierarchy level. The sender ID TLV, if configured at the hierarchy levels mentioned above, takes precedence over the global-level configuration.
