Data Sheet

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 dierence 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 dierence 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
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
M4200 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 trac by classifying trac, and enabling correct egress queue configuration
An associated Voice VLAN can be easily configured with Auto-VoIP for further trac 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
8-port PoE+ full power and NBASE-T compliant, 1G / 2.5G including two of these ports with 5G ability
All 8-port NBASE-T are backward compatible with standard Gigabit Ethernet (1000BASE-T) and Fast Ethernet (100BASE-T) speeds
IEEE 802.3at Power over Ethernet Plus (PoE+)
provides up to 30W power per port using 2 pairs
while oering 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
2-port 10G SFP+ uplinks for 8x2.5G to the Wave 2 11ac Access Points and 2x10G line-rate aggregation to the wiring closet
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 Dependancy feature enables or disables one or more ports based on the link state of one or more dierent ports
IPv6 support with multicasting (MLD for IPv6 filtering), static IPv6 routes (unicast), ACLs and QoS
