1.3 Mobile Unit Issues
This section describes various issues that may occur when working with the Mobile Units associated with the
wireless switch or associated Access Ports. Possible issues include:
• Access Port Adopted, but MU is Not Being Associated
• MUs Cannot Associate and/or Authenticate with Access Ports
• Poor Voice Quality Issues
1.3.1 Access Port Adopted, but MU is Not Being Associated
Access port associated with an MU is not yet being adopted. Table 1.8 provides suggestions to troubleshoot
this issue.
Table 1.8 Access Port Adopted, but MU is Not Being Associated Troubleshooting Notes
Possible Issue Suggestions to Correct
Unadopted access port Verify that the switch has adopted the access port with which the MU is trying to
associate.
WLAN is not authenticated Verify that the WLAN has been authenticated. Use the show command from the WLAN
Instance prompt (WS5000.(Cfg).WLAN.[WLAN_Name]>).
Incorrect ESSID applied to
the MU
Verify on the MU that the correct ESSID has been applied to the MU.
Encryption key(s) for the
MU is incorrect
• Verify that the encryption key(s) on the MU was entered correctly. The key on the
switch and the key on the MU must be identical (in a shared key authentication
system).
• Verify the encryption keys that the switch is using. Go to the Security Policy instance
(WS5000.(Cfg).SecurityPolicy.[Name]>) that was applied to the WLAN and verify that
the same encryption keys are being used at the MU.
Ethernet port configuration
issues
• Verify that the Ethernet port connected to the wired side of the network (sometimes
referred to as the RON NIC or rest of network NIC) has a valid configuration.
• If DHCP is used, verify that the Ethernet cable is connected to the same NIC upon
which DHCP services are enabled. The Ethernet port is set and viewed in the active
Ethernet Policy (EtherPolicy) context. (WS5000.(Cfg).Ethernet.[1]>
)
Incorrect security settings Verify that the correct security settings are applied to a WLAN in which the MU is tryng
to associate.
