Cisco Line Card E-Series Premium

The "E-Series" is composed of the Cisco Catalyst Series Supervisor Engine 6-E, E-Series line cards, and E-Series chassis that are designed for secure, flexible, nonstop communications with superior backward and forward compatibility delivering exceptional investment protection for organizations of all sizes. E-Series line cards increase the per slot switching capacity to 24 gigabits.

Functionally transparent
These line cards are functionally transparent; all the packet processing, queuing, buffering, and QoS occur in the supervisor engine. To that end, the E-Series line card acquires the features and capabilities of the installed supervisor engine. This architecture enables customers to easily upgrade all Ethernet line cards on their Cisco Catalyst Series systems to higher-layer switching functions by adding a supervisor engine. The simple design of the line cards results in a very high mean time between failures (MTBF), helping ensure high availability for a single connection to an end user.

Modular versatility
All line cards have some per slot bandwidth that allows network administrators to design a system that offers full dedicated bandwidth-to-server and switch-to-switch applications and still provide high performance over subscribed gigabit to the desktop. A modular centralized design allows customers to use their investment in high-performance line cards across the entire line of Cisco Catalyst Series chassis and supervisor engines.
