Záruka platná do End of Support 31. 10. 2029. Oznámení End of Life pro CISCO CBS350 Stránky produktu: CBS350-48FP-4G-EU Quick start guide: Quick start guide Switching capacity and forwarding rate (All switches are wire speed and nonblocking) Capacity in Millions of Packets per Second (mpps) (64-byte packets) 77,38 Switching Capacity in Gigabits per Second (Gbps) 104 Layer 2 switching Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support Fast convergence using 802.1w (Rapid Spanning Tree [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 8 groups Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation VLAN Support for up to 4,094 VLANs simultaneously Port-based and 802.1Q tag-based VLANs; MAC-based VLAN; protocol-based VLAN; IP subnet-based VLAN Management VLAN Private VLAN with promiscuous, isolated, and community port Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks Guest VLAN, unauthenticated VLAN Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication CPE VLAN Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers network wide zero-touch deployment of voice endpoints and call control devices Multicast TV VLAN Multicast 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) VLAN Translation Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs Selective Q-in-Q also allows configuring of Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag Layer 2 protocol tunneling over Q-in-Q is also supported Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) Generic 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 cable/port faults to prevent forwarding loops and black holing of traffic in switched networks 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 2K 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 IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols. Head-of-Line (HOL) blocking HOL blocking prevention Loopback Detection 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 IPv4 routing Wirespeed routing of IPv4 packets Up to 990 static routes and up to 128 IP interfaces IPv6 routing Wirespeed routing of IPv6 packets Layer 3 Interface Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface Classless Interdomain Routing (CIDR) Support for classless interdomain routing RIP v2 Support for Routing Information Protocol version 2 for dynamic routing Policy-Based Routing (PBR) Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL) DHCP Server Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Support for DHCP options 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 Bootstrap Protocol (BOOTP)/DHCP packets Security ecure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (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: Remote Authentication Dial-In User Service (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; MAC authentication IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through web browser to any host devices and operating systems 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. This avoids accidental topology loops STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers. 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 are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks. IP/MAC/Port Binding (IPMB) The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability Secure Core Technology (SCT) Makes sure that the switch wil

Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices Multicast TV VLAN Multicast 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) VLAN translation Support for VLAN one-to-one mapping, in which customer VLANs (C-VLANs) on an edge interface are mapped to service provider VLANs (S-VLANs), and the original C-VLAN tags are replaced by the specified S-VLAN Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs Selective Q-in-Q also allows configuring of the Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag Layer 2 protocol tunneling over Q-in-Q is also supported Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) GVRP and GARP enable automatic propagation and configuration of VLANs in a bridged domain Unidirectional Link UDLD monitors physical connections to detect unidirectional links caused by incorrect Detection (UDLD) wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks DHCP relay at Layer 2 Relay of DHCP traffic to a DHCP server in a 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; it supports 2000 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 IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols Head-of-Line (HOL) blocking HOL blocking prevention Loopback detection 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 IPv4 routing Wire-speed routing of IPv4 packets Up to 990 static routes and up to 128 IP interfaces IPv6 routing Wire-speed routing of IPv6 packets Layer 3 interface Configuration of a Layer 3 interface on a physical port, LAG, VLAN interface, or loopback interface Classless Interdomain Routing (CIDR) Support for CIDR Routing Information Protocol (RIP) v2 Support for RIP v2 for dynamic routing Policy-Based Routing (PBR) Flexible routing control to direct packets to a different next hop based on an IPv4 or IPv6 Access Control List (ACL) DHCP server Switch functions as an IPv4 DHCP server, serving IP addresses for multiple DHCP pools or scopes Support for DHCP options 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 Bootstrap Protocol (BOOTP)/DHCP packets Security Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (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, and MAC authentication IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems 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. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers IP Source Guard (IPSG) When IPSG 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 are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability Secure Core Technolog

Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices Multicast TV VLAN Multicast 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) VLAN translation Support for VLAN one-to-one mapping, in which customer VLANs (C-VLANs) on an edge interface are mapped to service provider VLANs (S-VLANs), and the original C-VLAN tags are replaced by the specified S-VLAN Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs Selective Q-in-Q also allows configuring of the Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag Layer 2 protocol tunneling over Q-in-Q is also supported Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) GVRP and GARP enable automatic propagation and configuration of VLANs in a bridged domain Unidirectional Link UDLD monitors physical connections to detect unidirectional links caused by incorrect Detection (UDLD) wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks DHCP relay at Layer 2 Relay of DHCP traffic to a DHCP server in a 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; it supports 2000 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 IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols Head-of-Line (HOL) blocking HOL blocking prevention Loopback detection 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 IPv4 routing Wire-speed routing of IPv4 packets Up to 990 static routes and up to 128 IP interfaces IPv6 routing Wire-speed routing of IPv6 packets Layer 3 interface Configuration of a Layer 3 interface on a physical port, LAG, VLAN interface, or loopback interface Classless Interdomain Routing (CIDR) Support for CIDR Routing Information Protocol (RIP) v2 Support for RIP v2 for dynamic routing Policy-Based Routing (PBR) Flexible routing control to direct packets to a different next hop based on an IPv4 or IPv6 Access Control List (ACL) DHCP server Switch functions as an IPv4 DHCP server, serving IP addresses for multiple DHCP pools or scopes Support for DHCP options 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 Bootstrap Protocol (BOOTP)/DHCP packets Security Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (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, and MAC authentication IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems 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. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers IP Source Guard (IPSG) When IPSG 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 are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding featur...

UBNT UniFi Switch USW-Pro-48-POE Gen2 Druhá generace UniFi switchů přináší řadu změn a vylepšení, switche byly přebudovány od základu. Oproti první generaci došlo k výraznému vylepšení toku vzduchu , který slouží k chlazení, a tak v porovnání je až 4x tišší* než první generace. * při okolní teplotě 25° a zatížení POE zdroje na 25% je switch 3,6x tišší * při okolní teplotě 25° a zatížení POE zdroje na 50% je switch 4,2x tišší * při okolní teplotě 25° a zatížení POE zdroje na 100% je switch 1,9x tišší Výbava USW-Pro-48-POE Gen2 má celkem 48 portů s funkcí POE-Out. Porty 1-40 podporují standardy 802.3af/at , porty 41-48 pak 802.3bt (60W) . Celkový POE budget činí 600W (celkový výkon zdroje 460W, 60W vlastní spotřeba switche). Jako Uplink poslouží dvojice portů 10G SFP+ se zpětnou kompatibilitou 1G SFP . Pro případ výpadku napájení nebo poruchy interního zdroje je možné switch připojit k záložnímu systému UniFi SmartPower, který obslouží až 6 podporovaných zařízení.
