Known Software Issues and Limitations
Release WT.01.10
■ SNMP (41053) — The dynamic DHCP bindings viewed in the web management interface
display the expiration time in GMT rather than accurately reflecting the configured time zone
offset.
Workaround: The expiration time is properly displayed in the output for the CLI command, show
ip dhcp binding.
■ SNMP (37189) — The module does not support “noAuthnoPriv” and “AuthnoPriv” security
levels for SNMPv3 users, but the CLI supports the commands for setting those levels.
Workaround: Configure SNMPv3 through the web management interface, which appropriately
allows only the “AuthPriv” security level.
■ SNMP (40001) — The SNMP port number for configuration of the trap destination is a
optional parameter in the CLI, while it is a mandatory parameter in web management
interface. The module administrator should use the configuration interface that best meets
their needs.
■ Wireless (40983) — Rate limiting is not applied to wireless stations that have roamed or
have reconnected to the network if cached PMK is configured.
Workaround: Disable PMK caching when vendor specific attributes are required for rate limiting
a wireless client (e.g. when using IDM). PMK caching is a default WPA2 value, and may be disabled
in the web management interface using Network Setup -> WLAN Setup -> Edit -> WPA/WPA2 ->
Fast Roaming -> and uncheck PMK Caching.
■ Wireless (41726) — Setting the country code after Rogue AP detection is enabled may
cause the module to reset continuously. This is an unlikely scenario since the country code
must be set prior to the module's ability to adopt radio ports and is unlikely to require a
second configuration. Best Practice: Set the country code prior to configuring the module.
Workaround: Disable Rouge AP detection prior to re-configuring the country code.
Release WT.01.10
■ ESPD (15310) — When PMK caching is enabled, and a client using WPA/WPA2 disconnects
and ages out of the table, log messages like the following may be seen (date, time, severity,
and IP address stamps removed for clarity).
espd: ESPd_emi_req() - Invalid OpCode
