Cisco Catalyst 3750-E Software
Cisco Catalyst 3750-E Series is available with either the IP Base or the IP Services feature set. The IP Base feature set includes advanced quality of service (QoS), a suite of security features, rate-limiting, access control lists, and basic static and Routing Information Protocol (RIP) routing capability. The IP Services feature set provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing—Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and so on. An Advanced IP Services feature set is also available for IPv6 routing.
Customers can transparently upgrade the software feature set in the Cisco Catalyst 3750-E Series Switches through Cisco IOS Software Activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is powered on. Based on the license’s type, Cisco IOS Software activates the appropriate feature set. License types can be changed, or upgraded, to activate a different feature set.
Investment Protection
The Cisco Catalyst 3750-E Series Switches are compatible with the Cisco Catalyst 3750 Series Switches, enabling customers to stack them together and thereby protect existing investment in the Cisco Catalyst 3750 Series Switches. The Cisco TwinGig Small Form-Factor Pluggable (SFP) converter module further protects customers’ investment in Cisco Catalyst 3750-E Series Switches by enabling migration from Gigabit Ethernet to 10 Gigabit Ethernet uplinks, as business needs require, without having to upgrade the switches.
Cisco StackWise Plus Technology
Cisco StackWise Plus technology is built on the highly successful StackWise technology, which is a premium stacking architecture optimized for Gigabit Ethernet. StackWise technology was designed to respond to additions, deletions, and redeployment while maintaining constant performance. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption. StackWise creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), auto-version checking, autoconfiguration, and more.
StackWise Plus supports all the features of StackWise and provides backward compatibility with the existing Cisco Catalyst 3750 Series Switches while enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco Catalyst 3750-E Series Switches. Local switching packets coming into a port in the Cisco Catalyst 3750-E Series Switch destined for another port in the same switch do not have to traverse through the stack ring, thus increasing the forwarding capacity of the switch.
