The fully managed M4100-50G-POE+ 48-Port Gigabit Ethernet Switch from NETGEAR operates on Layer 2 of the network and offers extensive routing functionality allowing network administrators to manage nearly every aspect of the network. With a 16K MAC address table size and up to 100 Gbps switching fabric the switch can handle a large amount of bandwidth to ensure virtually lag free connectivity. The network is even future proof as this managed switch comes compatible with IPv6 networking standards.
Engineered for Convergence
Automatic multi-vendor Voice over IP (VoIP) prioritization based on SIP, H323, and SCCP protocol Voice VLAN and LLDP-MED for automatic IP phones QoS and VLAN configuration Advanced classifier-based hardware for L2, L3, L4 security and prioritization Advanced Multicast filtering with IGMP and MLD snooping and querier modes
Layer-2+ with Static Routing
The switch comes with Port-based / VLAN-based / Subnet-based "static routing" Layer 2+ versions L3 fixed routes to the next hop towards the destination network are added to the routing table L3 routing is wire-speed in M4100 series hardware with 64 static routes (IPv4)
High-Value Performance and IPv6 ready
16K MAC addresses up to 100 Gb/s switching fabric, 9K jumbo frames, and Green Ethernet IPv4/IPv6 ingress traffic filtering (ACLs) and prioritization (QoS - DiffServ)
High-Availability and PoE+ Full Power Capability
Redundant power supply option for uninterruptible operation (RPS) External power supply option for PoE+ full power applications 1,440W with EPS
Industry Standard Management
Industry standard Command Line Interface (CLI) Fully functional NETGEAR web interface (GUI)
Layer-3 hardware with L2+ software affordability Built upon L3 hardware platform while Layer 2+ software package allows for better budget optimization Uses latest generation silicon low-power 40-nanometer technology L2 and L3 switching features (access control list, classification, filtering, IPv4 routing) are performed in hardware at interface line rate for voice, video, and data convergence Layer 2+ software packages provides straight forward IP static routing capabilities for physical interfaces, VLANs and subnets 16K MAC address table, 1K concurrent VLANs, and 64 static routes for SMB and small enterprise access layers Increased packet buffering with up to 12 Mb dynamically shared across all interfaces for most intensive applications Low latency at all network speeds Jumbo frames support of up to 9Kb accelerating storage performance for backup and cloud applications Broad portfolio of access layer solutions, with 48-port Gigabit Ethernet.
IEEE 802.3at Power over Ethernet Plus (PoE+) provides up to 30W per port Both IEEE 802.3at Layer 2 LLDP method and 802.3at 2-event classification methods are supported for compatibility with all PoE+ PD devices Automatic MDIX and Auto-negotiation on all ports select the right transmission modes (half or full duplex) as well as data transmission for crossover or straight-through cables dynamically for the admin 100 Mb/s backward compatibility on all SFP ports IPv6 support with multicasting (MLD for IPv6 filtering), ACLs and QoS
Ease of Use
Fully functional Web console (GUI) for IT admins who prefer an easy to use graphical interface Placement outside the wiring closet (conference rooms, offices, class rooms, sales floor in retail stores, etc) For secure deployment in open areas, desktop versions come with a Wall Mount Kit with four brackets Select desktop versions also come with a set of strong magnets for mounting on any metal surface Automatic configuration with DHCP and BootP Auto Install Both the Switch Serial Number and Switch primary MAC address are reported by a simple "show" command in the CLI Automatic Voice over IP prioritization with Auto-VoIP An associated Voice VLAN can be easily configured with Auto-VoIP for further traffic isolation When deployed IP phones are LLDP-MED compliant, the Voice VLAN will use LLDP-MED to pass on the VLAN ID, 802.1P priority and DSCP values to the IP phones, accelerating convergent deployments DHCP/BootP innovative auto-installation including firmware and configuration file upload automation Dual firmware image and configuration file for updates with minimum service interruption
Traffic control MAC filter and port security DHCP Snooping monitors DHCP traffic between DHCP clients and DHCP servers to filter harmful DHCP message and prevent DHCP spoofing attacks IP source guard and Dynamic ARP Inspection for malicious users traffic elimination Layer-2 / Layer 3-v4 / Layer 3-v6 / Layer 4 Access Control Lists (ACLs) can be binded to ports, Layer-2 interfaces, VLANs, and LAGs (Link Aggregation Groups or Port channel) for fast unauthorized data prevention and right granularity Bridge protocol data unit (BPDU) Guard allows the network administrator to enforce the Spanning Tree (STP) domain borders and keep the active topology consistent and predictable, unauthorized devices or switches behind the edge ports that have BPDU enabled will not be able to influence the overall STP topology by creating loops Spanning Tree Root Guard (STRG) enforces the Layer-2 network topology by preventing rogue root bridges potential issues when for instance, unauthorized or unexpected new equipment in the network may accidentally become a root bridge for a given VLAN Dynamic 802.1x VLAN assignment mode, including Dynamic VLAN creation mode and Guest VLAN/Unauthenticated VLAN are supported for rigorous user and equipment RADIUS policy server enforcement 802.1x MAC Address Authentication Bypass (MAB) Double VLANs (DVLAN - QoQ) pass traffic from one customer domain to another through the "metro core" in a multi-tenancy environment Private VLANs (with Primary VLAN, Isolated VLAN, Community VLAN, Promiscuous port, Host port, Trunks) provide Layer 2 isolation between ports that share the same broadcast domain Secure Shell (SSH) and SNMPv3 (with or without MD5 or SHA authentication) ensure SNMP and Telnet sessions are secured TACACS+ and RADIUS enhanced administrator management provides strict "Login" and "Enable" authentication enforcement for the switch configuration and authentication based on user domain in addition to user ID and password
