Data Sheet
The Cisco Catalyst 3750 Series is available with either the IP Base image or the IP Services
image. The IP Base image feature set includes advanced quality of service (QoS), rate-limiting,
access control lists (ACLs), and basic static and Routing Information Protocol (RIP) routing
capability. The IP Services image provides a richer set of enterprise-class features, including
advanced hardware-based IP unicast and multicast routing.
An additional Advanced IP Services license is also available. This license is required for IPv6
routing (Layer 3 switching).
Cisco StackWise Technology offers Stackable Resiliency
Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This
technology is designed to respond to additions, deletions, and redeployment while maintaining
constant performance. Cisco StackWise technology unites up to nine individual switches into
a single logical unit, using special stack-interconnect cables and stacking software. The individual
switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series
Switches. 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.
PRIMARY FEATURES AND BENEFITS
Ease of Use: "Plug-and-Play" Configuration
A working stack is self-managing and self-configuring. When switches are added or removed,
®
the master switch automatically loads the Cisco IOS Software revision running on the stack to
the new switch, loads the global configuration parameters, and updates all the routing tables to
reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco Catalyst 3750 Series stacks up to nine switches as a single logical unit for a total of 468
Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or
nine 10 Gigabit Ethernet ports. Additional port combinations can be created by connecting
the Cisco Catalyst 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10
Gigabit Ethernet units can be joined in any combination to evolve with network needs.
Return on Investment Through Lower Operations Costs
The automatic Cisco IOS Software version checking and loading of the global configuration
parameters provide the first level of operational time saving. The second level is added during
the event of an outage. When you remove a troubled switch from an existing stack of switches and
replace it with another switch, the master switch will recognize this as a maintenance outage and
automatically reload the port-level configuration that was on the previous switch without user
intervention. This allows IT managers to have local personnel in remote locations perform
maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving
thousands of dollars in operational costs.
