Network support
The Cisco VCS is an H.323 and SIP compliant device and is designed to be connected to an 802.3 IP
network. The first two 802.3 Ethernet ports are used which are labeled LAN 1 and LAN 2; the
remaining two are for future development. The Ethernet interfaces on the Cisco VCS support auto
speed and duplex detection as well as manually setting 1000Mbit Full Duplex, 100Mbit Full or Half
Duplex or 10Mbit Full or Half Duplex. The speed and duplex setting should be set to auto unless the
Ethernet switch that the Cisco VCS is connected to doesn't support auto-negotiation, in which case full
duplex should be used.
