Field Description
Level Maintenance level associated with this entry.
VLAN VLAN in which this error occurred.
MPID Identifier of remote MEP.
Interface Port at which the error was recorded
Remote MAC MAC address of remote MEP.
Reason Error types include:
LEAK – MA
x is associated with a specific VID list * , one or more of the VIDs
in this MA can pass through the bridge port, no MEP is configured facing
outward (down) on any bridge port for this MA, and some other MA
y , at a
higher maintenance level, and associated with at least one of the VID(s)
also in MA
x , does have a MEP configured on the bridge port.
VIDS – MA x is associated with a specific VID list
*
on this MA on the bridge
port, and some other MA y , associated with at least one of the VID(s) also
in MA x , also has an Up MEP configured facing inward (up) on some bridge
port.
EXCESS_LEV – The number of different MD levels at which MIPs are to be
created on this port exceeds the bridge's capabilities.
OVERLAP_LEV – A MEP is created for one VID at one maintenance level,
but a MEP is configured on another VID at an equivalent or higher level,
exceeding the bridge's capabilities.
* This definition is based on the IEEE 802.1ag standard. Current software for this switch only supports a single
VLAN per MA. However, since it may interact with other devices which support multiple VLAN assignments per
MA, this error message may be reported.
MA The maintenance association for this entry.
