Caveats
Caveats
This section lists open, resolved and closed caveats in release 4.2.176.51M.
Open Caveats
The following caveats are open (unresolved) in this release:
•
CSCsg88704–In large mesh deployments, the default configuration database settings of 512 and
1024 (system dependent) might not be large enough to address the needs of the network and
additional entries to the database are refused. This condition is true of large non-mesh deployments
as well.
1024 (system dependent) might not be large enough to address the needs of the network and
additional entries to the database are refused. This condition is true of large non-mesh deployments
as well.
Configuration database entries include MAC filter lists, access point MIC and SSC lists, dynamic
interfaces, management users and local net users.
interfaces, management users and local net users.
The following error messages are indicative of a configuration database that is full and not accepting
additional entries:
additional entries:
–
"Error in creating MAC filter"
–
"Authorization entry does not exist in Controller's AP Authorization List."
Workaround: Increase the configuration database to 2048 using the config database size 2048
command. In the controller GUI, you can set the configuration database setting at the following
window: Security > AAA > General.
command. In the controller GUI, you can set the configuration database setting at the following
window: Security > AAA > General.
•
CSCsj79606–In some cases, mesh neighbors for a RAP do not display in the WCS mesh link panel
(Monitor > Access Points > RAP Name > Mesh Links) when the RAP is operating without an
assigned bridge group name.
(Monitor > Access Points > RAP Name > Mesh Links) when the RAP is operating without an
assigned bridge group name.
Workaround: Check the controller GUI (All APs > Access Point Name > Neighbor Info Page)
or
CLI (show mesh neigh {summary | detail} Cisco_MAP) for the mesh neighbor information or
assign a bridge group name to the RAP.
assign a bridge group name to the RAP.
•
CSCsj98069–In some cases, after a RAP changes its bridge group name, the modified name does
not display in Cisco WCS; however, the modified name does display in the controller GUI and CLI.
not display in Cisco WCS; however, the modified name does display in the controller GUI and CLI.
Workaround: Use the controller GUI or CLI commands to access the required information for the
relevant RAP.
relevant RAP.
•
CSCsk43788–If a large number of mesh access point neighbors have an SNR of zero (0), these might
fully populate the Mesh Worst SNR Links report.
fully populate the Mesh Worst SNR Links report.
Workaround: When running the Mesh Worst SNR Link, select the Parent/Child option as the
Neighbor Type to display, to minimize the number of low SNR links reported. Additionally, you can
increase the number of listings that display from the default of 10.

•
CSCsl20845–It might take an extended period of time (an hour or more) for a change in attenuation
to cause the SNR for an existing AWPP neighbor entry to change accordingly. If an access point is
rebooted, the newly created AWPP neighbor entry has the expected SNR value immediately.
to cause the SNR for an existing AWPP neighbor entry to change accordingly. If an access point is
rebooted, the newly created AWPP neighbor entry has the expected SNR value immediately.
Workaround: None.
•
CSCsl63171–A controller might report a platinum QoS overflow condition to the message log even
when platinum QoS is not configured on any of the WLANs. The overflow condition is only reported
for 1510s.
when platinum QoS is not configured on any of the WLANs. The overflow condition is only reported

Workaround: None.
