TLAN network interface configuration commands
autonegotiate mode can be disabled if the ports on some data network
switches and routers are manually configured. For example, configuring a
port for 100BaseT full-duplex can disable autonegotiation on the signaling
link.
The Voice Gateway Media Card and the IP Phone default to half-duplex
mode when no autonegotiation signaling occurs. The result is that the Voice
Gateway Media Card and the IP Phone operate in half-duplex mode, while
the switch is in full-duplex mode. Communication continues, but random
packet loss can occur which affects the correct operation and voice quality.
Configure ports for autonegotiation, autosense.
Configure the speed and duplex setting of the TLAN network interface using
the following commands:
•
•
If the autonegotiation is disabled, and the speed and duplex mode are
forced using the CLI commands, Nortel recommends that half-duplex
mode be used to inter-operate with the far end when the far end is set to
autonegotiate.

tLanSpeedSet speed – this command configures the speed
of the TLAN network interface. By default, the network interface
autonegotiates to the highest speed supported by the switch. If the
switch is 10/100BaseT, the network interface negotiates to 100BaseT.
Use this command to debug Ethernet speed-related problems by forcing
the network interface to 10BaseT operation immediately. The duplex
mode setting is saved in NVRAM and read at start-up. The parameter
speed is set to the following:
10 – disables autonegotiation and sets speed to 10 Mb/s
10100 – enables autonegotiation
tLanDuplexSet duplexMode – this command immediately
configures the duplex mode of the TLAN network interface while
operating when autonegotiate is disabled and speed has been fixed to
10 Mb/s (or 10BaseT mode). The duplex mode is saved in NVRAM and
read at start-up. The parameter duplexMode is set to the following:
0 – enables full-duplex mode
1 – enables half-duplex mode
