802.1ag MIP Definitions
CFM Maintenance Intermediate Point (MIP) is a port which forwards CFM frames identified
by an equal or higher level and drops lower level, regardless of whether they are received
from the relay (Switch) or wire (Port) side.
MIP responds to CFM Loopback (unicast) and CFM Link Trace (multicast) messages of the
CFM Domain to which MIP belongs (identified by domain name and level in a message).
If MIPs are not configured on a device, CFM frames are forwarded on port according to
VLAN rules.
To define the domain MIPs
1. Invoke the pane of the domain whose MIPs are to be defined by doing one of the
following:
In the Network Element tree, under Service CFM, select the relevant domain.
In the Network Element tree, select Service CFM and double-click on the defined
domain.
2. In the CFM Domain pane, Configuration area, the currently defined MIPs for the
selected domain are displayed (e.g. ETH-1, COLAN etc.). To add or modify the defined
MIPs, click the Edit MIPs button. The following dialog appears.
