Datasheet

3
•
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
•
Spanning Tree Protocol (IEEE 802.1D):
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: support the IEEE
802.1Q (4094 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, STP Root
Guard: prevents network loops
•
8K MAC addresses: allows multiple Layer 2
devices to be networked through the switch
Layer 3 services
•
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
•
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
Layer 3 routing
•
Static IP routing: provides manually configured
routing; includes ECMP capability
Security
•
Secure Sockets Layer (SSL): encrypts all HTTP
traffic, allowing secure access to the
browser-based management GUI in the switch
•
IEEE 802.1X and RADIUS network logins:
control port-based access for authentication and
accountability
•
Port security: allows access only to specified
MAC addresses, which can be learned or
specified by the administrator
•
Automatic VLAN assignment: automatically
assigns users to the appropriate VLAN based on
their identity and location, and the time of day
•
STP BPDU port protection: blocks Bridge
Protocol Data Units (BPDUs) on ports that do not
require BPDUs, preventing forged BPDU attacks
•
STP Root Guard: protects root bridge from
malicious attack or configuration mistakes
