Layer 2 SNMP Switch
The latest Layer 2 Managed Switch from LevelOne is a perfect solution for young
and dynamic Offices with small network user groups. The G SW -0 8 9 0 provides
G igab it and F ib er Optic connection possib ilities that enab le a high-speed
network ing environment with long range connectivity to remote located
network s.
I t supports SN MP , W eb U I and C LI management interfaces and is eq uipped with 8
G igab it TP ports of which 2 are dual media ports that can accommodate
optional 1 0 / 1 0 0 / 1 0 0 0 B ase-T or SF P modules. The G SW -0 8 9 0 further implements Q oS
( Q uality of Service) , Mac F iltering P olicy, P ort Mirror, V LA N and full Layer 2
protocol.
Dual Media Port Support
The G SW -0 8 9 0 provides shared dual media port support on ports 7 and 8 for more
flex ib le fib er connectivity. SF P transceiver modules can b e connected to provide
short, medium and long distance fib er b ack b one capab ility.
Q oS w ith L ay er 4 C las s if ic ation Support
The switch provides support for Layer 2 8 0 2.1 1 p P riority Q ueue control as well as
programmab le higher layer classification and prioritiz ation to enab le enhanced
Q uality of Service ( Q oS) support for real time applications b ased on information
tak en from Layer 2 to 4 , such as V oI P and R eal-time video streaming applications.

The G SW -0 8 9 0 8 -port Layer 2 switch incorporates P ort Mirroring, Q -in-Q V LA N , A ccess C ontrol and P ort Trunk ing among its
network management features.
P ort mirroring copies traffic from a specific port to a target port. This mechanism helps track network errors or ab normal
pack et transmission without interrupting the flow of data.
The V LA N feature in the switch offers the b enefits of b oth security and performance. V LA N is applied to isolate traffic
b etween different users and thus provides b etter security. Limiting the b roadcast traffic to within the same V LA N
b roadcast domain also enhances performance. Q -in-Q , the use of doub le V LA N tags, is an efficient method for
enab ling Sub scrib er A ggregation.
8 0 2.1 x features enab le user authentication for each network access attempt. P ort security features allow you to limit
the numb er of MA C addresses per port in order to control the numb er of stations for each port. Static MA C addresses
can b e defined for each port to ensure only registered machines are allowed to access. B y enab ling b oth of these
features, you can estab lish an access mechanism b ased on user and machine identities, as well as control the numb er
of access stations.
The G SW -0 8 9 0 is also 8 0 2.3 ad P ort Trunk compliant. The G igab it ports can b e comb ined together to create a multi-link
load-sharing trunk . U p to 4 G igab it ports can b e set up per trunk for b andwidth up to 8 G b ps, all traffic is aggregated
b ased on MA C addresses, thus b alancing the traffic load. The switch supports up to 4 trunk ing groups. P ort trunk s are
useful for switch-to-switch cascading, providing very high full-duplex speeds
.
8 0 2 . 1 D & 8 0 2 . 1 w R apid Span n in g T ree C om patib le
F or mission critical environments with multiple switches supporting STP , you can configure the switches with a
redundant b ack up b ridge path, so transmission and reception of pack ets can b e guaranteed in the event of any
switch failure on the network .
B roadc as t/ Multic as t Storm C on trol
To limit too many b roadcast/ Multicast flooding in the network , b roadcast/ multicast storm control is used to restrict
ex cess traffic. Threshold values are availab le to control the rate limit for each port. P ack ets are discarded if the count
ex ceeds the configured upper threshold.
