50-Port Managed Switch with 2 Combo mini-GBIC |
Overview |
The Cisco 300 Series, part of the Cisco
Small Business line of network solutions, is a portfolio of affordable
managed switches that provides a reliable foundation for your business
network. These switches deliver the features you need to improve the
availability of your critical business applications, protect your
sensitive information, and optimize your network bandwidth to deliver
information and applications more effectively. Easy to set up and use,
the Cisco 300 Series provides the ideal combination of affordability and
capabilities for small businesses, and helps you create a more
efficient, better-connected workforce.
The Cisco 300 Series is broad portfolio of fixed-configuration managed
Ethernet switches. Models are available with 8 to 48 ports of Fast
Ethernet and 10 to 52 ports of Gigabit Ethernet connectivity, providing
optimal flexibility to create exactly the right network foundation for
your business. However, unlike other small business switching solutions
that provide managed network capabilities only in the costliest models,
all Cisco 300 Series Switches support the advanced security management
capabilities and network features you need to support business-class
data, voice, security, and wireless technologies. At the same time,
these switches are simple to deploy and configure, allowing you to take
advantage of the managed network services your business needs.
High Performance and Reliability: Get the high availability and
performance you need to support vital business applications while
reducing downtime.
Advanced Features: Control network traffic with advanced features such
as quality of service (QoS), Layer 3 static routing and IPv6 support.
Easy Setup and Management: Intuitive browser-based tools, mass
deployment capabilities, and consistent features across all models
simplify setup and configuration.
An Eco-Friendly Solution: Switches optimize power usage for energy
efficiency without compromising performance.
Peace of Mind: All Cisco 300 Series Switches are protected for the life
of the product by the Cisco Limited Lifetime Hardware Warranty, which
includes next-business-day advance replacement. |

Voice traffic is automatically assigned to
a voice-specific VLAN and treated with appropriate levels of QoS
Auto voice capabilities deliver network-wide zero touch deployment of
voice endpoints and call control devices. |
Multicast TV VLAN |
Multicast VLAN used for video applications
(Also known as MVR) |
Q-in-Q VLAN |
VLANs transparently cross a service
provider network while isolating traffic among customers |
Generic VLAN Registration Protocol
(GVRP)/Generic Attribute Registration Protocol (GARP) |

and configuring VLANs in a bridged domain |
Dynamic Host Configuration Protocol (DHCP)
Relay at Layer 2 |
Relay of DHCP traffic to DHCP server in
different VLAN. Works with DHCP Option 82 |
Internet Group Management Protocol (IGMP)
versions 1, 2, and 3 snooping |
IGMP limits bandwidth-intensive multicast
traffic to only the requesters; supports 1K multicast groups
(source-specific multicasting is also supported) |
IGMP Querier |
IGMP querier is used to support a Layer 2
multicast domain of snooping switches in the absence of a multicast
router. |
Head-of-line (HOL) blocking |
HOL blocking prevention |
Jumbo Frames |
Up to 10K in length |

SSH is a secure replacement for Telnet
traffic. SCP also uses SSH. SSH v1 and v2 are supported |
Secure Sockets Layer (SSL) |
SSL support: Encrypts all HTTPS traffic,
allowing highly secure access to the browser-based management GUI in the
switch |
IEEE 802.1X (Authenticator role) |
802.1X: RADIUS authentication and
accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple
host mode and single/multiple sessions
Supports time-based 802.1X
Dynamic VLAN assignment |
STP Bridge Protocol Data Unit (BPDU) Guard |
A security mechanism to protect the
network from invalid configurations. A port enabled for BPDU Guard is
shut down if a BPDU message is received on that port |
STP Root Guard |
Prevents a port from being selected as a
root port, effectively preventing bridges in the LAN segment connected
to the port from being a root bridge. |
DHCP snooping |
Filters out DHCP messages with
unregistered IP addresses and/or from unexpected or untrusted
interfaces. This prevents rogue devices from behaving as a DHCP Server. |
IP Source Guard (IPSG) |
When IP Source Guard is enabled at a port,
the switch filters out IP packets received from the port if the source
IP addresses of the packets have not been statically configured or
dynamically learned from DHCP snooping. This prevents IP Address
Spoofing. |
Dynamic ARP Inspection (DAI) |
The switch discards ARP packets from a
port if there is no static or dynamic IP/MAC bindings or if there is a
discrepancy between the source or destination address in the ARP packet.
This prevents man-in-the-middle attacks. |
IP/Mac/Port Binding (IPMB) |
The features (DHCP Snooping, IP Source
Guard, and Dynamic ARP Inspection) above work together to prevent DOS
attacks in the network, thereby increasing network availability |
Secure Core Technology (SCT) |
Ensures that the switch will receive and
process management and protocol traffic no matter how much traffic is
received |
Secure Sensitive Data (SSD) |
A mechanism to manage sensitive data (such
as passwords, keys, etc) securely on the switch, populating this data to
other devices, and secure autoconfig. Access to view the sensitive data
as plaintext or encrypted is provided according to the user configured
access level and the access method of the user. |
Layer 2 isolation Private VLAN Edge (PVE)
with community VLAN |
PVE (also known as protected ports)
provides Layer 2 isolation between devices in the same VLAN, supports
multiple uplinks |
Port security |
Locks MAC addresses to ports, and limits
the number of learned MAC addresses |
RADIUS/TACACS+ |
Supports RADIUS and TACACS authentication.
Switch functions as a client |
Storm control |
Broadcast, multicast, and unknown unicast |
RADIUS accounting |
The RADIUS accounting functions allow data
to be sent at the start and end of services, indicating the amount of
resources (such as time, packets, bytes, and so on) used during the
session. |
DoS prevention |
DoS attack prevention |
Congestion avoidance |
A TCP congestion avoidance algorithm is
required to minimize and prevent global TCP loss synchronization. |
ACLs |
Support for up to 512 rules
Drop or rate limit based on source and destination MAC, VLAN ID or IP
address, protocol, port, differentiated services code point (DSCP)/IP
precedence, TCP/ UDP source and destination ports, 802.1p priority,
Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP
packets, TCP flag, Time-based ACLs supported |

Priority levels |
4 hardware queues |
Scheduling |
Strict priority and weighted round-robin
(WRR)
Queue assignment based on DSCP and class of service (802.1p/CoS) |
