Description

Easy configuration and management: Cisco 250 Series switches are designed to be easy to deploy and use by small businesses or the partners that serve them:


  • High-speed desktop connectivity: Cisco 250 Series switches can quickly and securely connect employees working in small offices with one another and with all of the printers, servers, and other devices they use. High performance and reliable connectivity help speed up file transfers and data processing, improve network uptime, and keep your employees productive.
  • Flexible wireless connectivity: Cisco 250 Series switches work with Cisco and third-party wireless solutions to extend the reach of your network. With security features, Power over Ethernet (PoE), VLAN, and QoS, these switches are the perfect foundation to add business-grade wireless to a network.
  • The capability of up to 30W of power per port provided through the Ethernet cable means you can easily deploy innovative 802.11ac wireless technology to maximize workforce productivity.
  • Unified communications: The Cisco 250 Series provides QoS features to enable you to prioritize delay-sensitive traffic in your network and let you converge all of your communications solutions such as IP telephony and video surveillance onto a single Ethernet network. Cisco offers a complete portfolio of IP telephony and other unified communications products designed for small businesses, and Cisco 250 Series switches have been rigorously tested to help ensure easy integration and full compatibility with these and other vendor products.

Layer 2 switching

Spanning Tree Protocol (STP)

Standard 802.1d spanning tree support

Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default

Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported

Per-VLAN Spanning Tree Plus (PVST+) and Rapid PVST+ (RPVST+); 126 instances are supported

Port grouping/link aggregation

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

  Up to 4 groups
  Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG

VLAN

Support for up to 255 active VLANs simultaneously

Port-based and 802.1Q tag-based VLANs

Management VLAN

Guest VLAN

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)

Protocols for automatically propagating and configuring VLANs in a bridged domain

IGMP (versions 1, 2, and 3) snooping

Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 255 multicast groups (source-specific multicasting is also supported)

IGMP querier

Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

HOL blocking

Head-Of-Line (HOL) blocking

Loopback detection

Provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP

Layer 3 routing

IPv4 routing

Wire-speed routing of IPv4 packets

Up to 32 static routes and up to 16 IP interfaces

IPv6 routing

Wire-speed routing of IPv6 packets

Layer 3 interface

Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface

Classless Interdomain Routing (CIDR)

Support for CIDR

DHCP relay at Layer 3

Relay of DHCP traffic across IP domains

User Datagram Protocol (UDP) relay

Relay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packets

Security

SSL

Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch

Secure Shell (SSH) Protocol

SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported

IEEE 802.1X (authenticator role)

RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions

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, and so on) 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

Trustworthy systems

Trustworthy systems provide a highly secure foundation for Cisco products

Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])

Port security

Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses

RADIUS

Supports RADIUS authentication for management access. Switch functions as a client

Storm control

Broadcast, multicast, and unknown unicast

DoS prevention

Denial-of-Service (DoS) attack prevention

Multiple user privilege levels in CLI

Level 1, 7, and 15 privilege levels

Access Control Lists (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; ACL can be applied on both ingress and egress sides

Time-based ACLs supported

STP loopback guard

Provides additional protection against Layer 2 forwarding loops (STP loops)

Quality of service

Priority levels

8 hardware queues

Scheduling

Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS)

Class of service

Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS

Rate limiting

Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based

Congestion avoidance

A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization
