Maintenance Domain (MD) Level
: Maintenance Domains (MDs) are management spaces on a
network, typically owned and operated by a single entity. MDs are configured with Names and Levels,
where the eight levels range from 0 to 7. A hierarchal relationship exists between domains based on
levels. The larger the domain, the higher the level value.
Maintenance End Point: Points at the edge of the domain, define the boundary for the domain. A MEP
sends and receives CFM frames through the relay function, drops all CFM frames of its level or lower
that come from the wire side.
Link Trace: Link Trace messages otherwise known as Mac Trace Route are Multicast frames that a
MEP transmits to track the path (hop-by-hop) to a destination MEP which is similar in concept to User
Datagram Protocol (UDP) Trace Route. Each receiving MEP sends a Trace route Reply directly to the
Originating MEP, and regenerates the Trace Route Message.
Loop-back: Loop-back messages otherwise known as Mac ping are Unicast frames that a MEP
transmits, they are similar in concept to an Internet Control Message Protocol (ICMP) Echo (Ping)
messages, sending Loopback to successive MIPs can determine the location of a fault. Sending a
high volume of Loopback Messages can test bandwidth, reliability, or jitter of a service, which is similar
to flood ping. A MEP can send a Loopback to any MEP or MIP in the service. Unlike CCMs, Loop back
messages are administratively initiated and stopped.
Restart
This section lets you restart your router if necessary. Click
in the low right corner of each
configuration page.
If you wish to restart the router using the factory default settings (for example, after a firmware
upgrade or if you have saved an incorrect configuration), select Factory Default Settings to reset to
