DATA SHEET CISCO CATALYST 3750 SERIES SWITCHES ® ® The Cisco Catalyst 3750 Series switches are innovative switches that improve LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. This product series represents the next generation in desktop switches, and features Cisco StackWise™ technology, a 32-Gbps stack interconnect that allows customers to build a unified, highly resilient switching system—one switch at a time. Figure 1.
CONFIGURATIONS The Cisco Catalyst 3750 Series includes the following configurations: Cisco Catalyst 3750G-24TS—24 Ethernet 10/100/1000 ports and 4 Small Form-Factor Pluggable (SFP) uplinks Cisco Catalyst 3750G-24T—24 Ethernet 10/100/1000 ports Cisco Catalyst 3750G-12S—12 Gigabit Ethernet SFP ports Cisco Catalyst 3750-48TS—48 Ethernet 10/100 ports and 4 SFP uplinks Cisco Catalyst 3750-24TS—24 Ethernet 10/100 ports and 2 SFP uplinks Cisco Catalyst 3750-48PS—48 Ethernet 10/100 ports with IEEE 802.
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.
15.4 watts (W) for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. 10 Gigabit Ethernet Support—Increase Uplink Bandwidth for Gigabit Ethernet Deployments The Cisco Catalyst 3750 Series allows network managers to incrementally add IEEE 802.3ae compliant 10 Gigabit Ethernet connectivity in their wiring closets or GRID clusters, further facilitating and enhancing Gigabit Ethernet networks.
Feature Benefit DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server. IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and CWDM physical-interface support through a field-replaceable SFP module provides unprecedented flexibility in switch deployment. To help ensure that the switch can be quickly connected to the network and can pass traffic with minimal user intervention, there is a default configuration stored in Flash memory.
Feature Benefit Routing is possible across the stack. 128 switch virtual interfaces (SVIs) are recommended. Maximum of 1000 are supported (depending on the number of routes and multicast entries). 468 routed ports are supported per stack. Integrated Cisco IOS Software Features for Bandwidth Optimization Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall systems performance. IEEE 802.
Feature Features Benefit IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected. IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN irrespective of the authorized or unauthorized state of the port. IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client. IEEE 802.
Feature Benefit a server as well as to a portion or all of the network. 1000 access control entries (ACEs) are supported. MANAGEABILITY Superior Manageability Cisco IOS CLI support provides common user interface and command set with all Cisco routers and Cisco Catalyst desktop switches. Service Assurance Agent support facilitates service-level management throughout the LAN.
Feature Benefit routing protocols, ACLs, and QoS parameters. Cisco clustering now supports member discovery and cluster creation across a single Cisco Catalyst 3750 Series switch routed hop, allowing the entire LAN to be managed through a single Web interface (and with a single IP address, if desired). Cisco Network Assistant Software Guide Mode assists in the configuration of powerful advanced features by providing step-by-step instructions.
