IP address conict 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 aps 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 conguration with DHCP and BootP Auto Install eases large deployments with a scalable conguration les management capability, mapping IP addresses
and host names and providing individual conguration les 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 conguration
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 simplies 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 trafc by classifying trafc, and enabling correct egress queue conguration
An associated Voice VLAN can be easily congured with Auto-VoIP for further trafc 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, ac-
celerating 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 classication method fully supported for com-
patibility with most PoE+ PD devices
16-, 24-, 48- and 96-port 10G models with a variety of 10GBASE-T and 10GBASE-X SFP+ interfaces
M4300-96X offers 12 slots for 8x10G or 2x40G port expansion cards and hundreds of combinations
Large 10 Gigabit choice with SFP+ ports for ber or short, low-latency copper DAC cables; 10GBASE-T ports for legacy Cat6 RJ45 short connexions (up to 55m) and
Cat6A / Cat7 connections up to 100m
Automatic MDIX and Auto-negotiation on all portsselect the right transmission modes (half or full duplex) as well as data transmission for crossover or straight-through
cables dynamically for the admin
1G models (M4300-28G and M4300-52G, PoE+ versions included): the 10 Mbps / Half Duplex mode isn’t supported on ports 17-24 and 41-48
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 ltering and PIM-SM / PIM-DM for IPv6 routing), ACLs and QoS, static routing and
dynamic routing (OSPFv3) as well as Congured 6to4 and Automatic 6to4 tunneling for IPv6 trafc encapsulation into IPv4 packets
Ease of management and granular control
Dual rmware image and dual conguration le for transparent rmware updates / conguration changes with minimum service interruption
FlexiblePort-Channel/LAG (802.3ad - 802.1AX) implementation for maximum compatibility, fault tolerance and load sharing with any type of Ethernet channeling from
other vendors switch, server or storage devices conforming to IEEE 802.3ad - including static (selectable hashing algorithms) - or to IEEE 802.1AX with dynamic LAGs or
port-channel (highly tunable LACP Link Aggregation Control Protocol )
LACP mode automatically reverts to and from Static LAG, useful when the host isn’t LACP anymore, for instance during a factory reset or re-conguration
Unidirectional Link Detection Protocol (UDLD)and Aggressive UDLD detect and avoid unidirectional links automatically, in order to prevent forwarding anomalies in a
Layer 2 communication channel in which a bi-directional link stops passing trafc in one direction
Port names feature allows for descriptive names on all interfaces and better clarity in real word admin daily tasks
