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.
Mix-and-Match Switch Types: Pay as
You Expand Your Network
Stacks can be created with any combination of
Cisco Catalyst 3750 and Cisco Catalyst 3750-E
switches. Customers who need a mixture of 10/100
and 10/100/1000 ports, PoE, and wiring-closet
aggregation capability can incrementally develop
the access environment, paying only for what
they need. When uplink capacity needs to be
increased, you can easily upgrade your bandwidth
by adding a 10 Gigabit Ethernet version to the
stack and upgrade your Gigabit Ethernet links
with 10 Gigabit Ethernet on the existing fiber.
Integrated Wireless LAN Controller
The Cisco Catalyst 3750G Integrated Wireless LAN
Controller integrates wireless LAN controller
functions into the Cisco Catalyst 3750G Series
Switches and delivers improved operating
efficiency and WLAN security, mobility, and ease
of use for business-critical wireless LANs. The
Cisco Catalyst 3750G Integrated Wireless LAN
Controller delivers centralized security
policies, wireless intrusion prevention system
(IPS) capabilities, award-winning RF management,
QoS, and Layer 3 fast secure roaming for WLANs.
As a core component of the Cisco Unified
Wireless Network, the Cisco Catalyst 3750G
Integrated Wireless LAN Controller provides the
control, security, redundancy, and reliability
that network managers need to scale and manage
their wireless networks as easily as they scale
and manage their traditional wired networks.
Availability: Uninterrupted
Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 Series increases
availability for stackable switches. Each switch
can operate as both a master controller and a
forwarding processor. Each switch in the stack
can serve as a master, creating a 1:N
availability scheme for network control. In the
unlikely event of a single unit failure, all
other units continue to forward traffic and
maintain operation.
Smart Multicast: A New Level of
Efficiency for Converged Networks
With Cisco StackWise technology, the Cisco
Catalyst 3750 Series offers greater efficiency
for multicast applications such as video. Each
data packet is put onto the backplane only once,
which provides more effective support for more
data streams.
Superior Quality of Service Across
the Stack and at Wire Speed
The Cisco Catalyst 3750-E and 3750 Series offer
Gigabit and 10 Gigabit Ethernet speed with
intelligent services that keep everything
flowing smoothly, even at 10 times the normal
network speed. Mechanisms for marking,
classification, and scheduling deliver
best-in-class performance for data, voice, and
video traffic, all at wire speed.
Network Security: Granular Control
for the Access Environment
The Cisco Catalyst 3750 Series supports a
comprehensive set of security features for
connectivity and access control, including ACLs,
authentication, port-level security, and
identity-based network services with 802.1x and
extensions. This set of comprehensive features
not only helps prevent external attacks, but
also defends the network against
"man-in-the-middle" attacks, a primary concern
in today's business environment.
Single IP Management: Many
Switches, One Address
Each Cisco Catalyst 3750 Series stack is managed
as a single object and has a single IP address.
Single IP management is supported for activities
such as fault detection, VLAN creation and
modification, network security, and QoS
controls.
Jumbo Frames: Support for
High-Demand Applications
The Cisco Catalyst 3750 Series supports jumbo
frames on the 10/100/1000 configurations for
advanced data and video applications requiring
very large frames. All Cisco Catalyst 3750-E
Series switch models also support jumbo frames.
IPv6 Support
The Cisco Catalyst 3750 Series supports IPv6
routing in hardware for maximum performance. As
network devices grow and the need for larger
addressing and higher security becomes critical,
the Cisco Catalyst 3750 Series will be ready to
meet the requirement.
Standard PoE Support: Graceful
Addition of IP Communications
The Cisco Catalyst 3750 and 3750G PoE models
support Cisco IP phones and Cisco Aironet®
wireless LAN (WLAN) access points, as well as
any IEEE 802.3af-compliant end device. The Cisco
Catalyst 3750 and 3750G 24-port versions can
support 24 simultaneous full-powered PoE ports
at 15.4W 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:
Increased 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. This provides
investment protection to customers who want to
use their existing fiber plant, add uplink
bandwidth capacity to their switching stacks,
and provide higher performance to applications
and users. The Cisco Catalyst 3750-E Series
offers an even greater variety of 10 Gigabit
Ethernet port configuration switches.
Management Options
The Cisco Catalyst 3750 Series (Figure 5) offers
both a superior command-line interface (CLI) for
detailed configuration and Cisco Network
Assistant Software, a Web-based tool for quick
configuration based on preset templates. In
addition, CiscoWorks supports the Cisco Catalyst
3750 Series for networkwide management. Table 1
lists the features and benefits of the Cisco
Catalyst 3750 Series.

Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.
Automatic Cisco IOS Software version checking and updating help ensure that all stack members have the same software version.
Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface and global switch commands to detect
Cisco IP phones, classify traffic, and help enable egress queue configuration.
Master configuration management helps ensure that all switches are automatically upgraded when the master switch receives a new software version.
Autosensing on each non-SFP port detects the speed of the attached device and automatically configures the port for 10-, 100-, or 1000-Mbps
operation, easing switch deployment in mixed 10, 100, and 1000BASE-T environments.
Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel® groups or Gigabit EtherChannel groups to link to another switch,
router, or server.
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco
EtherChannel technology and PAgP.
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.
There is a default configuration to help ensure that the switch can be quickly connected to the network and can pass traffic with minimal
user intervention. This default configuration exists even if there is no configuration stored in Flash memory.
Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through)
is installed. |

EtherChannel technology across
different members of the stack for
high resiliency.
IEEE 802.1w Rapid Spanning Tree
Protocol (RSTP) provides rapid
spanning-tree convergence
independent of spanning-tree timers
and also offers the benefit of
distributed processing.
Stacked units behave as a single
spanning-tree node.
Per-VLAN Rapid Spanning Tree
(PVRST+) allows rapid spanning-tree
reconvergence on a per-VLAN
spanning-tree basis, without

balancing and redundancy.
Bandwidth aggregation up to 16
Gbps through 10 Gigabit EtherChannel
technology, 8 Gbps through Gigabit
EtherChannel technology, and up to
800 Mbps through Fast EtherChannel
technology enhances fault tolerance
and offers higher-speed aggregated
bandwidth between switches and to
routers and individual servers.
Uplink bandwidth can be easily
upgraded by adding a 10 Gigabit
Ethernet version to a wiring-closet
stack and replacing the Gigabit
Ethernet uplinks with 10 Gigabit
Ethernet without having to change
fiber pairs. |

Cross-stack QoS allows QoS to be
configured across the entire stack.
802.1p class of service (CoS) and
differentiated services code point
(DSCP) field classification is
provided, using marking and
reclassification on a per-packet
basis by source and destination IP
address, source and destination MAC
address, or Layer 4 Transmission
Control Protocol/User Datagram
Protocol (TCP/UDP) port number.
Cisco control-plane and data-plane
QoS ACLs on all ports help ensure
proper marking on a per-packet
basis.
4 egress queues per port help
enable differentiated management of
up to 4 traffic types across the
stack.
Shaped Round Robin (SRR)
scheduling helps ensure differential
prioritization of packet flows by
intelligently servicing the ingress
queues and egress queues.
Weighted Tail Drop (WTD) provides
congestion avoidance at the ingress
and egress queues before a
disruption occurs.
Strict priority queuing helps
ensure that the highest-priority
packets are serviced ahead of all
other traffic.
There is no performance penalty
for highly granular QoS capability. |
Granular Rate
Limiting |
Cisco committed information rate
(CIR) function provides bandwidth in
increments as low as 8 Kbps.
Rate limiting is provided based on
source and destination IP address,
source and destination MAC address,
Layer 4 TCP/UDP information, or any
combination of these fields, using
QoS ACLs (IP ACLs or MAC ACLs),
class maps, and policy maps.
Asynchronous data flows upstream
and downstream from the end station
or on the uplink are easily managed
using ingress policing and egress
shaping.
Up to 64 aggregate or individual
policers are available per Fast
Ethernet or Gigabit Ethernet port. |
Network Security
|
Networkwide Security
Features |
IEEE 802.1x allows dynamic, port-based security, providing user authentication.
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 802.1x with an ACL assignment allows for specific identity-based security policies regardless of where the user is connected.
IEEE 802.1x with guest VLAN allows guests without 802.1x clients to have limited network access on the guest VLAN.
Cisco security VLAN ACLs on all VLANs prevent unauthorized data flows from being bridged within VLANs.
Cisco standard and extended IP security router ACLs define security policies on routed interfaces for control-plane and data-plane traffic.
Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.
Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic
during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S.
export restrictions.
Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic.
Dynamic ARP Inspection helps ensure user integrity by preventing malicious users from exploiting the insecure nature of the ARP protocol.
DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses. This feature is used by other primary security features to prevent
a number of other attacks such as ARP poisoning.
IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table
between client's IP and MAC address, port, and VLAN.
Bidirectional data support on the Switched Port Analyzer (SPAN) port allows a Cisco Intrusion Detection System (IDS) to take action when an
intruder is detected.
TACACS+ and RADIUS authentication
facilitate centralized control of
the switch and restrict unauthorized
users from altering the
configuration.
MAC address notification allows
administrators to be notified of
users added to or removed from the
network.
DHCP Snooping helps administrators
with consistent mapping of IP to MAC
addresses. This can be used to
prevent attacks that attempt to
poison the DHCP binding database and
to rate-limit the amount of DHCP
traffic that enters a switch port.
Port security secures the access
to an access or trunk port based on
MAC address.
After a specific timeframe, the
aging feature removes the MAC
address from the switch to allow
another device to connect to the
same port.
Trusted boundary provides the
ability to trust the QoS priority
settings if an IP phone is present
and to disable the trust setting in
the event that the IP phone is
removed, thereby preventing a
malicious user from overriding
prioritization policies in the
network.
Multilevel security on console
access prevents unauthorized users
from altering the switch
configuration.
The user-selectable
address-learning mode simplifies
configuration and enhances security.
Bridge protocol data unit (BPDU)
guard shuts down Spanning Tree
PortFast-enabled interfaces when

troubleshooting.
Cisco VLAN Trunking Protocol (VTP)
supports dynamic VLANs and dynamic
trunk configuration across all
switches.
Cisco Group Management Protocol
server functions allow a switch to
serve as the
Cisco Group Management Protocol
router for client switches. The IP
Services image is required.
IGMP snooping provides fast client
joins and leaves of multicast
streams and limits
bandwidth-intensive video traffic to
only the requestors.
Remote Switch Port Analyzer
(RSPAN) allows administrators to
remotely monitor ports in a Layer 2
switch network from any other switch
in the same network.
For enhanced traffic management,
monitoring, and analysis, the
Embedded Remote Monitoring (RMON)
software agent supports 4 RMON
groups (history, statistics, alarms,
and events).
Layer 2 traceroute eases
troubleshooting by identifying the
physical path that a packet takes
from source to destination.
All 9 RMON groups are supported
through a SPAN port, which permits
traffic monitoring of a single port,
a group of ports, or the entire
stack from a single network analyzer
or RMON probe.
Domain Name System (DNS) provides
IP-address resolution with
user-defined
device names.
Trivial File Transfer Protocol
(TFTP) reduces the cost of
administering software upgrades by
downloading from a centralized
location.
Network Timing Protocol (NTP)
provides an accurate and consistent
timestamp to all intranet switches.
Multifunction LEDs per port for
port status; half-duplex and
full-duplex mode; and 10BASE-T,
100BASE-TX, and 1000BASE-T

Power Connectors |
Customers can provide power to a switch by using either the internal power supply or a redundant power system (Cisco RPS 2300 or the Cisco RPS 675). The connectors are located at the back of the switch.
Internal power supply connector
The internal power supply is an autoranging unit.
The internal power supply supports input voltages between 100 and 240VAC.
Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
Cisco RPS Connector
The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC input and supplies DC output to the switch.
The connector automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic.
Only the Cisco RPS 2300 (model PWR-RPS2300) or the Cisco RPS 675 (PWR675-AC-RPS-N1=) should be attached to the redundant-power-supply receptacle. |
