SDM (System Data Management, or switch database)
templates allow for granular system resources
distribution depending on IPv4 or IPv6 applications
• ARP Entries (the maximum number of entries in the IPv4 Address Resolution Protocol ARP cache for
routing interfaces)
• IPv4 Unicast Routes (the maximum number of IPv4 unicast forwarding table entries)
• IPv6 NDP Entries (the maximum number of IPv6 Neighbor Discovery Protocol NDP cache entries)
• IPv6 Unicast Routes (the maximum number of IPv6 unicast forwarding table entries)
• ECMP Next Hops (the maximum number of next hops that can be installed in the IPv4 and IPv6 unicast
forwarding tables)
• IPv4 Multicast Routes (the maximum number of IPv4 multicast forwarding table entries)
• IPv6 Multicast Routes (the maximum number of IPv6 multicast forwarding table entries)
Loopback interfaces management for routing protocols administration
Private VLANs and local Proxy ARP help reduce broadcast with added security
Management VLAN ID is user selectable for best convenience
Industry-standard VLAN management in the command line interface (CLI) for all common operations such as VLAN creation; VLAN names; VLAN “make static” for
dynamically created VLAN by GVRP registration; VLAN trunking; VLAN participation as well as VLAN ID (PVID) and VLAN tagging for one interface, a group of interfaces
or all interfaces at once
Simplied VLAN conguration with industry-standard Access Ports for 802.1Q unaware endpoints and Trunk Ports for switch-to-switch links with Native VLAN
System defaults automatically set per-port broadcast, multicast, and unicast storm control for typical, robust protection against DoS attacks and faulty clients which can,
with BYOD, often create network and performance issues
IP Telephony administration is simplied with consistent Voice VLAN capabilities per the industry standards and automatic functions associated
Comprehensive set of “system utilities” and “Clear” commands help troubleshoot connectivity issues and restore various congurations to their factory defaults for
maximum admin efciency: traceroute (to discover the routes that packets actually take when traveling on a hop-by-hop basis and with a synchronous response when
initiated from the CLI), clear dynamically learned MAC addresses, counters, IGMP snooping table entries from the Multicast forwarding database etc...
Syslog and Packet Captures can be sent to USB storage for rapid network troubleshooting
Replaceable factory-default conguration le for predictable network reset in distributed branch ofces without IT personnel
All major centralized software distribution platforms are supported for central software upgrades and conguration les management (HTTP, TFTP), including in highly
secured versions (HTTPS, SFTP, SCP)
Simple Network Time Protocol (SNTP)can be used to synchronize network resources and for adaptation of NTP, and can provide synchronized network timestamp either
in broadcast or unicast mode (SNTP client implemented over UDP - port 123)
Embedded RMON (4 groups) and sFlow agents permit external network trafc analysis
Engineered for convergence and AV-over-IP
Audio (Voice over IP) and Video (multicasting) comprehensive switching, ltering, routing and prioritization
Auto-VoIP, Voice VLAN and LLDP-MED support for IP phones QoS and VLAN conguration
IEEE 1588 (section 10 and 11.5) PTPv2 Transparent
Clock (TC) End-to-End implementation considering
the residence time of PTPv2 packets from ingress to
egress
• The 48-port 10G models (M4300-24X24F, M4300-48X, M4300-48XF) don’t support PTPv2 E2E TC
• 1-step Transparent Clock mode, using the residence time of the PPTPv2 packet at the egress port level in
Standalone mode, or Stack Master only
• On M4300-52G and M4300-52G-PoE+ models, PTPv2 is supported between port 1 and port 24, and be-
tween port 25 and port 48
• The “Sync & Delay_Req” eld of passing/egressing out PTPv2 packets is updated with the residence time in
the switch, the other elds in PTPv2 packets (“Announce”, “Delay_Resp”, “Pdelay_Req” and “Pdelay_Resp”)
are not updated
NETGEAR IGMP Plus
™
enhanced implementation for
automatic multicast across a M4300 / M4500 L2
network (Spine and Leaf topologies), removing the
need for L3 PIM routing
• IGMP Plus is pre-congured on default VLAN 1 out of the box in all M4300 and M4500 models (M4300:
starting 12.0.8.x release)
• IGMP Plus can be congured on another VLAN for automatic IGMP across switches on that VLAN (uplinks
can make part of that VLAN in trunk mode)
• IGMP Plus allow AV-over-IP devices (TX/Encoders and RX/Decoders) to be connected across multiple M4300
and M4500 switches in a star topology
• New show igmpsnooping group command in CLI and GUI displays the Source and Group IP addresses
along with their corresponding MAC addresses that are learnt through IGMP Snooping in a given VLAN on a
given interface
