Key Features in the Device
DHCP Option 82:
This feature enables the Dynamic Host Configuration Protocol (DHCP)
relay agent information (option 82) (ES-2410C switch) to include
information about itself and the attached client when forwarding DHCP
requests from a DHCP client to a DHCP server via Trust Port. The DHCP
server can use this information to assign IP addresses
、
gateway
、
subnet
mask
、
DNS for each subscriber of a service-provider network.
QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active
VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:
Support ingress and egress per port bandwidth control.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON:
SNMP agent and RMON MIB. In the device, SNMP agent is a client
software which is operating over SNMP protocol used to receive the
command from SNMP manager (server site) and echo the corresponded
data, i.e. MIB object. Besides, SNMP agent will actively issue TRAP
information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of
the SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON
MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643) and
so on.
IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping
is used to establish the multicast groups to forward the multicast
packet to the member ports, and, in nature, avoid wasting the
bandwidth while IP multicast packets are running over the network.
