ProSAFE® Intelligent Edge Managed Switches Data Sheet M4300 series NETGEAR PVSTP implementation (CLI only) follows the same rules than other vendor's Per VLAN STP for strict interoperability • Including industry-standard PVST+ interoperability • PVSTP is similar to the MSTP protocol as defined by IEEE 802.1s, the main difference being PVSTP runs one instance per VLAN • In other words, each configured VLAN runs an independent instance of PVSTP • FastUplink feature immediately moves an alternate port with lowest cost to forwarding state when the root port goes down to reduce recovery time • FastBackbone feature selects new indirect port when an indirect port fails NETGEAR PVRSTP implementation (CLI only) follows the same rules than other vendor's Per VLAN RSTP for strict interoperability • Including industry-standard RPVST+ interoperability • PVRSTP is similar to the RSTP protocol as defined by IEEE 802.1w, the main difference being PVRSTP runs one instance per VLAN • In other words, each configured VLAN runs an independent instance of PVRSTP • Each PVRSTP instance elects a root bridge independent of the other • Hence there are as many Root Bridges in the region as there are VLANs configured • Per VLAN RSTP has in built support for FastUplink and FastBackbone IP address conflict detection performed by embedded DHCP servers prevents accidental IP address duplicates from perturbing the overall network stability IP Event Dampening reduces the effect of interface flaps on routing protocols: the routing protocols temporarily disable their processing (on the unstable interface) until the interface becomes stable, thereby greatly increasing the overall stability of the network Ease of deployment Automatic configuration with DHCP and BootP Auto Install eases large deployments with a scalable configuration files management capability, mapping IP addresses and host names and providing individual configuration files to multiple switches as soon as they are initialized on the network Both the Switch Serial Number and Switch primary MAC address are reported by a simple "show" command in the CLI - facilitating discovery and remote configuration operations M4300 DHCP L2 Relay agents eliminate the need to have a DHCP server on each physical network or subnet • DHCP Relay agents process DHCP messages and generate new DHCP messages • Supports DHCP Relay Option 82 circuit-id and remote-id for VLANs • DHCP Relay agents are typically IP routing-aware devices and can be referred to as Layer 3 relay agents Automatic Voice over IP prioritization with Auto-VoIP simplifies most complex multi-vendor IP telephones deployments either based on protocols (SIP, H323 and SCCP) or on OUI bytes (default database and user-based OUIs) in the phone source MAC address; providing the best class of service to VoIP streams (both data and signaling) over other ordinary traffic by classifying traffic, and enabling correct egress queue configuration 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 Versatile connectivity 24- and 48-port 1G models with 10G uplinks, including 2-port 10GBASE-T and 2-port 10GBASE-X SFP+ IEEE 802.3at Power over Ethernet Plus (PoE+) provides up to 30W power per port using 2 pairs while offering backward compatilibity with 802.3af • IEEE 802.3at Layer 2 LLDP method and 802.3at PoE+ 2-event classification method fully supported for compatibility with most PoE+ PD devices 16-, 24- and 48-port 10G models with a variety of 10GBASE-T and 10GBASE-X SFP+ interfaces Large 10 Gigabit choice with SFP+ ports for fiber or short, low-latency copper DAC cables; 10GBASE-T ports for legacy Cat6 RJ45 short connexions (up to 50m) and Cat6A / Cat7 connections up to 100m 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 Link Dependency feature enables or disables one or more ports based on the link state of one or more different ports IPv6 full support with IPv6 host, dual stack (IPv4 and IPv6), multicasting (MLD for IPv6 filtering and PIM-SM / PIM-DM for IPv6 routing), ACLs and QoS, static routing and dynamic routing (OSPFv3) as well as Configured 6to4 and Automatic 6to4 tunneling for IPv6 traffic encapsulation into IPv4 packets Page 7 of 49
