CHAPTER 4 INITIALIZATION

SETTING UP THE LAN PORTS FOR SUITABLE COMMUNICATION MODES

NOTE: When you connect a communication device (such as a HUB) to the LAN1 (10/100BASE-TX) port of the In-Skin Router, and either the In-Skin Router or that communication device is set up for auto negotiation, transfer efficiency may be impaired due to the mismatch between the com- munication modes of these devices, although a link has been established.

If this occurs, set the communication rate of the LAN1 (10/100BASE-TX) port appropriately (to 10 Mbps, 100 Mbps, or auto negotiation), as well as the communication direction (to full du- plex, half duplex, or auto negotiation), referring to the following combination table.

Setting in the In-Skin Router		Communication rate and direction assumed
		if both the rate and direction of the opposite
Rate	Direction
		device are set to auto negotiation
Auto negotiation	Auto negotiation	100	Mbps, full duplex
Auto negotiation	Fixed at full duplex	Undefined (may impair transfer efficiency)
Auto negotiation	Fixed at half duplex	100	Mbps, half duplex
Fixed at 100 Mbps	Auto negotiation	100	Mbps, full duplex
Fixed at 100 Mbps	Fixed at full duplex	Undefined (may impair transfer efficiency)
Fixed at 100 Mbps	Fixed at half duplex	100	Mbps, half duplex
Fixed at 10 Mbps	Auto negotiation	10 Mbps, full duplex
Fixed at 10 Mbps	Fixed at full duplex	Undefined (may impair transfer efficiency)
Fixed at 10 Mbps	Fixed at half duplex	100	Mbps, half duplex

Checking of the settings

Check the settings with the show interfaces command.

ix1000 − 01 (config − FastEthernet0) # exit Enter

ix1000 − 01 (config) # show interfaces FastEthernet0.0 Enter Interface FastEthernet0.0 is up

(Omitted)

FastEthernet statistics :

Physical address 00 : 00 : 4c : a4 : 03 : 18

Half − duplex, 10Mb/s, 100BaseTX

(Omitted)

ix1000 − 01 (config) #

Check the settings.

(In this example, half duplex, 10 Mbps)
