8000GS Series

The Allied Telesis 8000GS Series of high-performance Gigabit Ethernet stackable

switches provides high performance Layer 2 switching in an affordable, xed-

conguration platform. This Series offers 24 10/100/1000T, PoE and non-PoE

versions, as well as a 48-port 10/100/1000T model. All models support four

combo 1Gbps SFP slots and two integrated stacking connectors that deliver

a total of 20Gbps stacking bandwidth. The stacking capability integrated into

this platform is congured as a resilient ring topology designed to provide high

reliability and simplied management for higher port density applications. Support

for jumbo Ethernet frames enables higher throughput of time-sensitive data.

* Enhanced Stacking up to 24 units

Securing the Network Edge

Protocols such as IEEE 802.1x port-based

authentication guarantee that only known

users are connected to the network,

ensuring the protection of your data.

Unknown users who physically connect

can be isolated to a predetermined part of

your network, offering guests such benets

as Internet access while ensuring the

integrity of your private network data.

Secure Management

Only authorized administrators can access

the management interface of the 9000 and

8000GS Series. Security protocols such

as SSL, SSH and SNMPv3 facilitate this

protection of your network for both local

or remote connections.

Access Control Lists (ACLs)

Access Control Lists enable inspection of

incoming frames and classify them based

on various criteria. Specic actions can

then be applied to these frames in order

to more effectively manage the network

trafc. Typically ACLs are used as a

security mechanism, either permitting or

denying entry for frames in a group, but

can also be applied to QoS.

Ideal Branch Ofce and Wiring

Closet Connectivity

Powerful line rate performance makes

this switch ideal for branch ofces or the

wiring closet of larger ofces. The state-of-

the-art QoS capability of these products

ensures reliable delivery of advanced

network services such as voice and video,

while effectively controlling the continually

increasing trafc needs found in today’s

networks.
