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.
Checking of the settings
Check the settings with the show interfaces command.
Setting in the In-Skin Router Communication rate and direction assumed
if both the rate and direction of the opposite
device are set to auto negotiation
