Стекируемый коммутатор Gigabit Ethernet с 24 портами 10/100/1000T и 4 совмещенными портами SFP
1 руб.

Модель 8000GS/24 – это недорогой управляемый стекируемый коммутатор Gigabit Ethernet, идеально подходящий для наращивания числа портов на границе сети с использованием стекирования. Коммутатор выполнен в форм-факторе 1RU и оснащен четырьмя совмещенными портами SFP для соединений Gigabit Ethernet, а также двумя выделенными интерфейсами для стекирования. При этом управление различными возможностями (такими, как агрегация каналов, виртуальные локальные сети, зеркалирование портов) осуществляется на уровне всего стека.

All the QoS Needed in the Wiring Closet
for Today’s Voice and Data Networking
• Eight priorities assigned to four queues
• IEEE 802.1p for Layer 2 QoS
• DSCP (DiffServ) for Layer 3 QoS
• IEEE 802.1p to DSCP remarking traffic ready for
transport to the Layer 3 core of the network
• Layer 2 and Layer 3 Access Control Lists (ACL)

Securing the Network at its Most
Vulnerable Point
• IEEE 802.1x and RADIUS network login: for
advanced control of user authentication and
• Guest VLAN: to ensure visitors or unauthorized
users connect only to services defined by IT. E.g.
• TACACS+: for ease of management security
• Layer 2 and Layer 3 Access Control Lists (ACL)
• Port MACAddress security options

Access Control Lists (ACLs)
Access Control Lists enable inspection of
incoming frames and classify them based on
various criteria. Specific actions can then be
applied to these frames in order to more
effectively manage the network traffic. Typically
ACLs are used as a security mechanism, either
permitting or denying entry (hence the name
Access Control) for frames in a group, but can
also be applied to QoS.

Supported ACL types are:
• IP ACLs – applicable to IP packet type.
All classification fields are related to IP
• MAC ACLs – classification fields are based on
Layer 2 fields.
