Интерфейсные или линейные модули Cisco (linecard, interfacemodule) позволяют расширить маршрутизатор или модульную платформу требуемым функционалом, включая нужные порты доступа на скоростях 1GbE, 10GbE, 40GbE или 100GbE. В основном под каждую серию модульных маршрутизаторов или шасси Cisco выпускает различные модули расширения под определенную линейку устройств, но в большинстве случаев, модуль можно использовать не в одной линейке (напр. интерфейсный модуль Cisco EHWIC-4ESG совместим с маршрутизаторами Cisco ISR G2 1900 серии, 2900 серии и 3900 серии).
В зависимости от платформы, интерфейсный модуль Cisco может поддерживать небольшое количество портов, как в случае с небольшими маршрутизаторами Cisco 1900 серии, так и 48 портов в одном модуле для шасси 7600 серии. Интерфейсные модуля и платы Cisco поддерживают множество различных интерфейсов и могут использоваться как в сети Ethernet, так и в других сетях передачи данных.
