11.2.1 SOAM Configuration Error List
The Configuration Error List is a list of bridge ports, aggregated ports, and VIDs that are
incorrectly configured. The list is updated internally for every configuration change. The following
Configuration Errors can be detected on a 9145E NID:
• Conflicting VIDs: This error condition occurs when two or more MAs or MEGs in the sys-
tem, at the same level, have overlapping VIDs associated with them, and for each MA, an
UP MEP is configured in the system. That is, it is an error to have two UP MEPs monitor-
ing the same VLAN, at the same level.
• CFMLeak: This error condition occurs when two or more MAs or MEGs, having overlap-
ping VIDs, are configured such that for the lower level MA, there is no UP MEP associ-
ated with a given port, and there are no down MEPs in the entire system; while for the
higher level MA, there is a MEP associated with a port (the port where the error is
detected). That is, there is no boundary for the lower level MA in the system, while there
is a boundary for the upper level MA
To view the SOAM Configuration Errors screen:
1. On the SOAM System Level Configuration screen (Figure 11-8), type 11 and press Enter.
The Configuration Errors screen (Figure 11-9) opens.
2. The Configuration Error screen lists the VLAN, port, and error. Figure 11-9 shows a
typical error on the user port and two typical errors on the network port.
3. Press Esc to return to the SOAM System Level Configuration screen. Press Esc again to
return to the SOAM Configuration screen.
