Caveats
•
CSCsg80305—When 16 SSIDs are configured, client devices sometimes fail to associate to the 16th
SSID.
SSID.
Workaround: Save the configuration and reload the UC520.
•
CSCsg88872—Client devices can sometimes associate to an access point when WEP is set to
optional on the client but set to required on the access point.
optional on the client but set to required on the access point.
Workaround: None.
•
CSCsg90606—When an SSID is configured with WPA version 2+CCKM and encryption is set to
TKIP, wireless clients fail to authenticate to the access point.
TKIP, wireless clients fail to authenticate to the access point.
Workaround: None.
•
CSCsh44876—The access point incorrectly lists client wired interface IP addresses in show dot11
assoc command output and in the association table.
assoc command output and in the association table.
Workaround: None.
•
CSCsh84949—Wireless client fails to receive multicast data stream.
Workaround—Configure no ip igmp snooping on the access point.
•
CSCsh86675—1310 Bridge continuously authenticates and deauthenticates with LEAP enabled.
Occurs when 1310 configured as an access point and associating with an Intel 2915 802.11g radio.
Client running LEAP associates and disassociates with the client deauthenticating.
Client running LEAP associates and disassociates with the client deauthenticating.
•
CSCsi10705—The throughput on dual-radio 1200 series access points is sometimes lower than the
throughput on a single-radio 1200 series access points.
throughput on a single-radio 1200 series access points.
Workaround: None.
•
CSCsj03461—1310 series cannot authenticate to root 1310 using EAP-TLS when certificate is
downloaded using SCEP method.
downloaded using SCEP method.
EAP-TLS authentication fails only if the certificate is downloaded using SCEP method.
Workaround—Download the certificate using cut-and-paste method.
•
CSCsj25335—IP Redirect feature towards DNS packet is not documented.
However, the IP Redirection Application Note mentions that BOOTP/DHCP, DNS, and broadcast
data should not be redirected.
data should not be redirected.
When the IP Redirect feature is configured under the dot11 radio interface, the destination MAC
address of the DNS Packet is rewritten with the host Mac Address specified under the ip redirect
host <IP address> command.
address of the DNS Packet is rewritten with the host Mac Address specified under the ip redirect
host <IP address> command.
•
CSCsj53216—Supplicants sometimes fail to receive DHCP addresses when the access point
changes the VLAN at logon.
changes the VLAN at logon.
Conditions: EAP authentication with access point in VLAN x and client device in VLAN y.
Workaround: If possible, put the access point and the client device in the same VLAN.
•
CSCsj86643—When you use the a workgroup bridge (WGB) to simulate a WMM/TSPEC client, the
WGB/pagent-sourced UP 6 traffic (followed by a TSPEC) is downgraded to best effort when ACM
is enabled. This downgrade occurs because the access point and WGB shared driver code assumes
that the workgroup bridge is an access point and the uplink traffic is invalid, and thus downgrades
all packets.
