Коммутаторы Cisco Catalyst 2960 серии являются линейкой коммутаторов с фиксированной конфигурацией и портами Fast Ethernet и Gigabit Ethernet, имеющие расширенные LAN сервисы для предприятий начального уровня и сетей удаленного офиса. Коммутаторы Cisco Catalyst 2960 поддерживают передачу голоса, данных и видео, а также безопасный доступ. Кроме того, они предоставляют масштабируемое управление по мере изменения потребностей вашего бизнеса.
Коммутаторы Cisco Catalyst 2960 поддерживают Intelligent features (создание сложных списков управления доступом, расширенная безопасность), комбинированные гигабитные аплинки (медный 10/100/1000BASE-T Ethernet или SFP-модуль для перехода в другую среду - Cisco 1000BASE-SX, 1000BASE-LX, 1000BASE-ZX, 100BASE-FX, 100BASE-LX, CWDM SFP). Также, устройства Catalyst 2960 поддерживают QoS, пошаговый Rate Limiting, ACL (на базе MAC или IP адресов, портов UDP/ TCP) и multicast services, возможность регулировать скорость передачи на каждом порту с шагом 64 кбит, Link Aggregation для организации более скоростных соединений между коммутаторами и серверами, возможность организации транковых соединений на каждом порту с помощью тэгов 802.1q, до 255 VLAN на коммутатор, до 4000 VLAN ID и управление через Cisco Network Assistant (поддерживает широкий спектр моделей коммутаторов от Cisco Catalyst 2960 до Cisco Catalyst 4506).
Прошивка коммутаторов Cisco Catalyst 2960 выпускается в образах LAN Base и Lan Lite Image. LAN Base имеет более широкий функционал, включая улучшенную безопасность (ACLs), DHCP Snooping и добавочные функции по контролю доступа - Web authentication и расширения 802.1x, добавочные возможности установок качества обслуживания QoS, поддержка избыточного питания RPS и большого количества SFP-портов. Функции Flex Links и Link State Tracking, увеличенное количество поддерживаемых VLANs (до 256), IPv6 Host, MLD Snooping, LLDP-MED, RSPAN, MVR, DHCP Option 82, и IP SLA (responder) и прочее.
