Important Notes
Pings and Link Tests Sometimes Fail to Clients with both Wired and Wireless
Network Connections
Network Connections
When you ping or run a link test from an access point to a client device installed in a PC running
Microsoft Windows 2000, the ping or link test sometimes fails when the client has both wired and
wireless connections to the LAN. Microsoft does not recommend this configuration. For more
information, refer to Microsoft Knowledge Base article 157025 at this URL:

Limitation to PAgP Redundancy on Switches Connected by Bridge Links
When running PAgP on switched connected to series bridges, for ethernet traffic redundancy and load
balance be aware that PAgP switchover takes at least 30 seconds, which is too slow to maintain certain
traffic (for example, TCP) when switching from port to the other. There is no workaround for this
limitation.

Default IP Address Behavior
When an unconfigured access point/bridge boots, it attempts to obtain an IP address from a DHCP server.
If it fails to locate a DHCP server, it continues attempting to request an IP address from the DHCP server.
To eliminate this behavior, you must access the access point/bridge through its console port and assign
a static IP address.

To eliminate this behavior, you must access the access point/bridge through its console port and assign
a static IP address.
If you want to reset the access point/bridge to its default settings and a static IP address, use the write
erase or erase /all nvram command. If you want to erase everything including the static IP address, in
addition to the above commands, use the erase and erase boot static-ipaddr static-ipmask command.

Caution
You should never delete any of the system files prior to resetting defaults or reloading software.
Ethernet Duplex Settings
The access point/bridge is implemented with an unmanaged and unconfigurable 10/100baseT switch
embedded in the power injector. All ports on the switch are set for auto-speed, auto-duplex, and
auto-MDIX. Port 0 on the switch is used for the coaxial link to the access point/bridge. Port 1 on the
switch is used for the RJ45 jack on the power injector.

auto-MDIX. Port 0 on the switch is used for the coaxial link to the access point/bridge. Port 1 on the
switch is used for the RJ45 jack on the power injector.
The speed and duplex settings on the access point/bridge FastEthernet0 interface apply only to the link
between the access point/bridge port and port 0 on the power injector. They are entirely independent of
the speed and duplex settings used on the RJ45 port (port 1) on the power injector. Therefore, for best
performance, you should not change the port 0 default settings. The default settings result in a 100Mbps,
full-duplex configuration used on the link between the access point/bridge and the power injector switch.

full-duplex configuration used on the link between the access point/bridge and the power injector switch.
The connecting port (the port on the device connected to the power injector’s RJ45) must be set to half
duplex or (preferably) auto duplex. If it is set to auto-duplex, the power injector switch port should
negotiate full duplex. If it is set to half duplex, the power injector switch port falls back to half-duplex.
The connecting port must not be configured to full duplex. If it is, the power injector switch port fails to
negotiate full-duplex, falls back to half duplex, which causes a duplex mismatch.
