138208 A flush message is being sent to source learning for all SAPs
of a service even though only one SAP is down.
There is no known workaround
at this time.
138473 Larger customer frames to the remote end are dropped in the
VPLS tunnel. The default tunnel size is 1.5K. And the actual
tunnel size for data is less than 1.5K after accounting for the
MPLS/VPLS header overhead. Any customer frame > 1480
bytes will be dropped..
Workaround is to change the
tunnel size to be larger than
1.5K. This change will have to
be made end-to-end including
all PE and P routers over which
the tunnel is setup
138800 Flooded traffic in a VPLS (eg. multicast, broadcast, unknown
dest MAC) that uses a static-lsp as a SDP for the service may
not foward after a takeover is issued.
Flushing the ARP cache several
minutes after the takeover may
resolve the forwarding entries.
Note this may cause a slight
disruption in other traffic using
the service.
139641 It can take 1-2 minutes for CMM to display Active LSP list
using the 'show service sdp detail' command after takeover.
Wait two minutes before
running the command. Traffic is
being forwarded; this is a
display issue only.
139609 MAC addresses learned under a service distribution point are
displayed in the MAC address table even after traffic is
stopped.
Use the 'no mac-address-table
learned' command to flush the
stale MACs.
139719 When entering MPLS related commands the following
message may appear: "ERROR: System busy, try again later"
Determine that no other users
are currently displaying MPLS
data - type: debug set

140151 Service Manager supports tying only 14 Static LSPs to a SDP
instead of IPD-like 16.
There is no workaround at this
time.

129999 Authenticated PC MAC is not displayed in MAC table and LPS
table when LPS is configured on an authenticated port.
There is no known workaround at
this time.
134856 MAC address table indicates supplicants MAC address as
bridging instead of UNP when classified according to UNP for
RADIUS server down policy.

138458 If multiple SFTP sessions are opened, an error message may be
seen when the sessions are closed.
There is no known workaround at
this time.
138770 In a stacked environment on a takeover where the NI is reset,
the polling frame from the switch does not reach the supplicant.
There is no known workaround at
this time.
114844 The AVLAN pre-authentication temporary IP address will
appear in the ARP table.
There is no known workaround at
this time. This has no affect on
