•
Advanced QoS and traffic shaping: provides
traffic prioritization using IEEE 802.1p Quality of
Service (QoS) and Type of Service (TOS) with
Differentiated Services Code Point (DSCP) and
ingress/egress rate shaping to help ensure that
critical time-sensitive traffic like voice receives the
priority needed for quality communications
•
VLANs: segment the network by grouping users
based on their data or traffic exchange
requirements; help ensure improved use of available
bandwidth as traffic flow is directed according to
the needs of the business
•
Link aggregation (trunking): groups together
up to 8 ports automatically using Link Aggregation
Control Protocol (LACP), or manually, to form an
ultra-high-bandwidth connection to the network
backbone; helps prevent traffic bottlenecks
•
Selectable queue configurations: increase
performance by selecting the number of queues and
associated memory buffering that best meet the
requirements of your network applications
•
Spanning Tree Protocol (STP/RSTP/MSTP):
improves network compatibility, scalability, and
availability
•
IGMP snooping: multicast filtering improves
network performance, instead of flooding traffic to
all ports
•
Unique voice features: automatic assignment of
voice traffic separates VLANs (“auto-voice VLAN”);
advanced voice QoS, traffic shaping, multicast
filtering, and PoE support delivers the support
necessary for quality voice communications
•
Fiber uplink: provides greater distance
connectivity using Gigabit fiber uplinks
•
PoE support (PWR model only): provides
power for IP phones, wireless LAN access points,
and other IEEE 802.3af-compliant devices over the
same cable used for data; lowers total cost of
ownership because there is no need to run
additional electrical wiring; supports prestandard
PoE plus, allowing the switch to deliver up to 30 W
of power
Resiliency and high availability
•
IEEE 802.1w Rapid Convergence Spanning
Tree Protocol: increases network uptime through
faster recovery from failed links
•
IEEE 802.1D Spanning Tree Protocol (STP):
provides redundant links while preventing network
loops
•
IEEE 802.1s Multiple Spanning Tree: provides
high link availability in multiple VLAN environments
by allowing multiple spanning trees
•
Link aggregation (trunking): groups together
up to 8 ports automatically using Link Aggregation
Control Protocol (LACP), or manually, to form an
ultra-high-bandwidth connection to the network
backbone; helps prevent traffic bottlenecks
•
Redundant Power Supply (365 PWR model
only): DC power supply provides additional PoE
budget of up to 740 W for high power applications
like Gigabit IntelliJack switches
Layer 2 switching
•
VLAN support and tagging: supports IEEE
802.1Q (4,094 VLAN IDs) and 256 VLANs
simultaneously
•
Jumbo packet support: supports up to
9220-byte frame size to improve performance of
large data transfers
•
Spanning Tree: fully supports standard IEEE
802.1D Spanning Tree Protocol, IEEE 802.1w
Rapid Spanning Tree Protocol for faster
convergence, and IEEE 802.1s Multiple Spanning
Tree Protocol
•
Port mirroring: duplicates port traffic (ingress
and egress) to a local or remote monitoring port
•
BPDU tunneling: transmits Spanning Tree
Protocol BPDUs transparently, allowing correct tree
calculations across service providers, WANs, or
MANs
•
Spanning Tree/MSTP, RSTP, and STP Root
Guard: prevent network loops
•
8K MAC addresses: allows multiple Layer 2
devices to be networked through the switch
Layer 3 services
•
User Datagram Protocol (UDP) helper
function: allows UDP broadcasts to be directed
across router interfaces to specific IP unicast or
subnet broadcast addresses and prevents server
spoofing for UDP services such as DHCP
•
Address Resolution Protocol (ARP):
determines the MAC address of another IP host in
the same subnet; supports static ARPs; gratuitous
ARP allows detection of duplicate IP addresses;
proxy ARP allows normal ARP operation between
subnets or when subnets are separated by a Layer 2
network
