Additional information
The alarm is raised when the number
of MAC address entries in the FIB
reaches or exceeds the VPLS site high
watermark specified by
l2fwd.SiteFib.highWatermark. The
alarm clears when the number of
MAC address entries in the FIB drops
below the VPLS site low watermark
specified by
l2fwd.SiteFib.lowWatermark. The
alarm can be raised against a VPLS
site, L2 access interface, or spoke
SDP binding.
The alarm is raised when a protected
MAC address that is distributed to all
sites in a VPLS is removed from a site
using CLI.
The alarm is raised when the number
of MRP attribute table entries for a
service site exceeds the high
watermark specified by
l2fwd.SiteMrp.mrpAttrTblHighWater
mark. The alarm clears when the
number of MRP attribute table
entries for the site drops below the
low watermark specified by
l2fwd.SiteMrp.mrpAttrTblLowWater
mark.
The alarm is raised when a customer
NE is configured with a bridge
priority of zero. The SDP binding that
connects to the customer device is
subsequently blocked.
The alarm is raised when a a
restricted SAP receives a relearn
request for a protected MAC address.
The alarm is raised when a SAP
detects an STP exception condition,
for example, one-way
communication or a downstream
loop. The alarm clears when the STP
condition changes.
The alarm is raised when a SAP
detects an STP root guard violation.
