Speed or duplex mismatch

A duplex mismatch on the WLAN can cause the WLAN IP Telephony Manager 2245 to not
operate properly. Double-check WLAN connections and interfaces to ensure that they are all
configured as full-duplex.
In rare instances, the message Speed or Duplex mismatch error can occur during the bootup
sequence of the IP Telephony Manager 2245.
If this situation occurs, verify all devices connected to the WLAN IP Telephony Manager 2245
are configured correctly and no duplex mismatch is found. If all configurations are correct,
reboot the IP Telephony Manager 2245. The error message must be cleared.
Avaya recommends that you
• do not configure the Ethernet Link, on the SVP-II Configuration screen, to auto-negotiate.
• use either 100/full or 10/full, as is appropriate for the network.
• configure the ethernet switch port to match the 2245 Ethernet Link.
