Special features of the XG2000 series are shown below:
Item
Function
Features
Throughput 400Gbit/s
Latency
350ns (Exclude latency of XFPs)
Switching mode
Either store-and-forward or cut-through is selectable.
MAC address learning table
size
16384 entries
MAC address learning
SVL (Shared VLAN Learning), IVL (Independent VLAN Learning),
user selectable.
Jumbo frame support
Up to 16KB (16128 bytes).
Flow control
IEEE802.3x compliant pause frame control. Possible to specify flow
control options for each port.
Storm control
Detects the broadcast storm status to prevent the traffic from
overflowing the network and avoid degrading overall system
performance.
Port security
Possible to restrict port access based on a source MAC address.
Ingress rate control
Supports by-port ingress rate control.
Port mirroring
Possible to monitor the incoming/outgoing traffic by port mirroring.
Basic Switch Functions
Link pass through
Possible to synchronize the link state of a monitored port with the
link state of a single or multiple ports.
Link aggregation
(Static and LACP)
Possible to increase bandwidth and redundancy. (Up to 10 ports for
each link).
Also supports IEE802.3ad LACP.
Scalability
Uplink Filter
Filtering multicast, broadcast and unlearned unicast frames from
leaf nodes to uplink. Possible to configure fat tree using several XG
series.
Redundancy IEEE802.1D
STP,
IEEE802.1w RSTP
Possible to make a redundant and loop-free network using Rapid
Spanning Tree Protocol (upward compatible with Spanning Tree
Protocol).
IEEE802.1Q VLAN
Max. 128 groups.
Filtering Ingress/egress filtering
VLAN support
Multiple VLAN
Possible to create multiple tag-based VLAN, with user VLAN tag
identifier.
IEEE802.1p QoS
DiffServ
Supports 4 traffic classes based on VLAN priority or DSCP
(DiffServ Code Point) of IPv4/IPv6.
QoS
Scheduling Strict,
DRR(Deficit Round Robin), DRR
Multi-cast support
IGMP snooping
Prevents unnecessary forwarding of multicast traffic to ports to
reduce unnecessary multicast traffic.
Traffic statistics
Possible to analyze traffic and errors, using traffic statistics.
Network Management
SNMP agent
Can be used in conjunction with an SNMP manager, supporting
MIBs, including Standard MIB, Bridge MIB, and RMON MIB.
Console by
serial/management LAN
Dedicated management LAN is isolated from the serial interface
and 10 Gigabit ports to secure the device.
CLI
Allows the user to provide environment settings and operation
management using command line interface (CLI).
