Radio Preamble
The radio preamble is a section of data at the head of a packet that contains
information the access point and client devices need when sending and receiving
packets. The drop-down menu allows you to select a long or short radio preamble:
• Long—A long preamble ensures compatibility between the access point and
all early models of Cisco Aironet Wireless LAN Adapters (PC4800 and
PC4800A).
• Short—A short preamble improves throughput performance. Cisco Aironet's
Wireless LAN Adapter supports short preambles. Early models of Cisco
Aironet's Wireless LAN Adapter (PC4800 and PC4800A) require long
preambles.
Ethernet Configuration
This section describes how to configure the access point’s Ethernet port. Use the
Ethernet pages in the management system to set the Ethernet port configuration.
The Ethernet pages include:
• Ethernet Identification—Contains the basic locating and identity information
for the Ethernet port.
• Ethernet Hardware—Contains the setting for the access point’s Ethernet port
connection speed.
• Ethernet Advanced—Contains settings for the operational status of the access
point’s Ethernet port. You can also use this page to make temporary changes
in port status to help with troubleshooting network problems.
• Ethernet Port—Lists key information on the access point’s Ethernet port.
Entering Identity Information
You use the Ethernet Identification page to enter basic locating and identity
information for the access point’s Ethernet port. Figure 3-10 shows the Ethernet
