Determining alias IP addresses
When diagnosing network problems, (for example, to ping the wireless
handset), it is useful to know the mapping between the alias IP addresses
as displayed by various Call Server commands and the physical IP address
of the wireless handset. There is no single command that provides this
information; however, the administrator can determine it in two ways:
1. If the wireless handset IP address is statically configured, the
administrator can look at the IP address of the wireless handset using
the Admin menu, which is available when the wireless handset is
powered on.
2. After the wireless handset is operating and in standby mode, the
administrator can look at the User Preferences menu to find the alias IP
address of the wireless handset.
For more information, see WLAN Handsets Fundamentals (NN43001-505).
Troubleshooting coverage issues
Coverage issues are best resolved by adding and relocating APs as
required. Overlap issues can be resolved by reassigning channels to
the APs or by relocating the APs. For more information, see
Appendix
"Troubleshooting and diagnosis of WLAN IP Telephony installations" (page
173)
.
