Key Features in the Device
QoS:
The offers 5 kinds of powerful QoS functions. There are Per Port
switch
Priority that you can assign each port to different precedence, VLAN Tag
priority that can make precedence of 8 priorities to meet 802.1p standard,
IP TOS Classification affected by TOS fields of IP header, TCP/UDP Port
Classification and IP DiffServe Classification act on DSCP field of IP
Header.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) and IEEE 802.1s (MSTP: Multiple 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, VLAN MIB (802.1Q, RFC2674),
Ethernet 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.
PoE PSE:
12 port IEEE802.3af PSE Endpoint with 48VDC power through RJ-45 pin1,
2, 3, and 6.
