VES-1000 Series Ethernet Switch
1-2 Getting to Know the VES-1000 Series
STP (Spanning Tree Protocol)
STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a
device to interact with other STP-compliant devices in your network to ensure that only one path exists between
any two stations on the network.
IGMP Snooping
With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that group. IGMP
Snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing
through your switch.
VDSL Modes and Rates
The VES-1000 Series supports the following DSLAM VDSL modes. VDSL mode can be set per port.
10Base-S giving upstream rates from 1.56 Mbps to 18.75 Mbps and downstream rates of 4.17 Mbps
Kbps to 16.67 Mbps.
ANSI Mode giving upstream rates from 1.56 Mbps to 6.25 Mbps and downstream rates of 4.17 Mbps
to 16.67 Mbps.
ETSI Mode giving upstream rates from 1.56 Mbps to 6.25 Mbps and downstream rates of 4.17 Mbps
to 12.50Mbps.
