30 Chapter 1 Getting to Know Your Switch
• Port-based VLAN
• IEEE 802.1Q VLAN
• 802.1x Authentication
• Limit dynamic port MAC address learning
• Static MAC address filtering
Bandwidth Control
• The ES-3148 supports rate limiting in 1Mbps increments allowing you to create different
service plans.
• The ES-3148 supports IGMP snooping enabling group multicast traffic to be only
forwarded to ports that are members of that group; thus allowing you to significantly
reduce multicast traffic passing through your switch.
• Broadcast storm control
Quality of Service
• Eight queues so you can ensure mission-critical data gets delivered on time.
• Follows the IEEE 802.1p priority setting standard based on source/destination MAC
addresses.
1.3 Hardware Features
This section describes the hardware features of the ES-3148.
Power
The ES-3148 requires 100~240VAC/1.5A power.
48 10/100 Mbps Fast Ethernet Ports
Connect up to 48 computers or switches to the 10/100Mbps auto-negotiating, automatic cable
sensing (auto-MDIX) Ethernet RJ-45 ports. All Ethernet ports support:
• IEEE 802.3/3u/3z/3ab standards
• Back pressure flow control in half duplex mode
• IEEE 802.3x flow control in full duplex mode
Two Gigabit Ethernet Ports for Uplink Modules
The gigabit ports allow the ES-3148 to connect to another WAN switch or daisy-chain to other
switches.
