IP address planning
The WLAN IP Telephony Manager 2245, the optional WLAN Application
Gateway 2246, and each of the wireless handsets and APs associated with
them, requires an IP address.
The wireless handsets can be configured to use DHCP or can be assigned a
static IP address. If there is no DHCP Server, the system administrator must
determine what IP addresses are to be used for static addressing. As well,
whether static IP addressing or DHCP is used, a pool of alias IP addresses
must be configured on the WLAN IP Telephony Manager for the use of the
wireless handsets. Ensure that the pool of alias IP addresses is reserved
exclusively for the use of the wireless handsets.
Refer to “WLAN IP Telephony Manager 2245 configuration” on page 67 for
information on configuring a static IP address on a WLAN IP Telephony
Manager 2245. Refer to “Configuring the WLAN Application Gateway 2246
IP address” on page 161 for information on configuring a static IP address for
a WLAN Application Gateway 2246.Refer to “WLAN Handsets 2210/2211
configuration” on page 83 for information on configuring a static IP address
on the WLAN Handsets 2210/2211. Refer to the vendor-specific
documentation for information on assigning IP addresses to the APs.
Record the static IP address assignments and store them in a safe place.
IMPORTANT!
The master WLAN IP Telephony Manager 2245 must have an IP
address statically configured.
If using DHCP for the rest of the network, the DHCP Server must have
the static IP address of the master WLAN IP Telephony Manager 2245
configured on it. If using DNS, the DNS Server must have the static IP
address of the master WLAN IP Telephony Manager 2245 configured on
it.
