48-port 10/100 PoE Stackable Managed Switch Cisco SF500-48P-K9-G5

- 48-port 10/100 PoE Stackable Managed Switch w/Gig Uplinks.

- Simple-to-use graphical interfaces reduce the time required to deploy, troubleshoot, and manage the network and allow you to support sophisticated capabilities without increasing IT head count.

- The switches also support Textview, a full command-line interface (CLI) option for partners that prefer it.

- Using Auto Smartports intelligence, the switch can detect a network device connected to any port and automatically configure the optimal security, quality of service (QoS), and availability on that port.

- Cisco Discovery Protocol (CDP) discovers Cisco devices and allows devices to share critical configuration information, simplifying network setup and integration.

- Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your switches and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations.

Management VLAN
PVE (Private VLAN Edge), also known as Protected Port, with multiple uplinks
Guest VLAN Unauthenticated VLAN Protocol-based VLAN CPE VLAN
Dynamic VLAN assignment via Radius server along with 802.1x client authentication
Voice VLANVoice 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 VLANMulticast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR).
Q-in-QVLANs transparently cross over a service provider network while isolating traffic among customers.
GVRP/GARPGeneric VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain.
Unidirectional Link Detection (UDLD)UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networks
DHCP Relay at Layer 2Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82.
IGMP (versions 1, 2, and 3) snoopingInternet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 1K (1024) and 4K (for SG500X in native mode) multicast groups (source-specific multicasting is also supported).
IGMP querierIGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
HOL blockingHead-of-line (HOL) blocking.
Jumbo FramesFrames up to 9K (9216) bytes in length.
Layer 3
IPv4 routingWirespeed routing of IPv4 packets
Up to 2K (2048) static routes and up to 256 IP interfaces

Layer 3 InterfaceConfiguration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface
CIDRSupport for Classless Inter-Domain Routing
RIP v2 (on 500X)Support for Routing Information Protocol version 2, for dynamic routing
VRRP (on 500X)Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are supported. Up to 255 virtual routers are supported.
DHCP ServerSwitch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options
DHCP Relay at Layer 3Relay of DHCP traffic across IP domains.
User Datagram Protocol (UDP) RelayRelay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets.
Stacking
Hardware stackUp to 8 units in a stack. Up to 416 ports managed as a single system with hardware failover.
High availabilityFast stack failover delivers minimal traffic loss.
Plug-and-play stacking configuration/managementMaster/backup for resilient stack control

Hot swap of units in stack
Ring and chain stacking options Auto stacking port speed Flexible stacking port options
High-speed stack interconnectsCost-effective 5G copper and high-speed 10G Fiber and Copper interfaces.
Hybrid stackA mix of SF500, SG500, and SG500X in the same stack (10/100, Gigabit, and 10 Gigabit).
Security
SSHSSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.
SSLSecure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.
IEEE 802.1X (Authenticator role)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
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.
