Network Access Control (NAC)
» NAC allows for unprecedented control over user
access to the network, in order to mitigate threats
to network infrastructure. Furthermore, if multiple
users share a port multi-authentication is used.
Different users on the same port can be assigned
into different VLANs, and so given different levels of
network access. Additionally, a Guest VLAN can be
configured to provide a catch-all for users who aren’t
authenticated.
Network in a Box
» Simplifies administration by integrating several
network services into the x600 switch.
» Radius Server checks the identity of users to keep the
network safe.
» Storm Control ensures a robust network by managing
the amount of traffic allowed on the network, and
dealing with any unexpected surges.
» DHCP server automates the distribution of network
addresses to PCs.
» A centralized Timekeeper ensures the network is
always working in full synchronicity.
» Loop Protection guards against accidental wiring
mistakes.
VCStack™ (Virtual Chassis Stacking)
» Create a VCStack with up to four units. VCStack
provides a highly available system where network
resources are spread out across stacked units,
reducing the impact if one of the units fails.
Aggregating switch ports on different units across the
stack provides excellent network resiliency.
EPSRing™ (Ethernet Protection Switched
Rings)
» EPSR and 10 Gigabit Ethernet allow several x600
Series to form a high speed protected ring capable
of recovery within as little as 50ms. This feature is
perfect for high performance and high availability in
enterprise networks.
» SuperLoop Protection enables a link between
two EPSR nodes to be in separate EPSR domains,
improving redundancy and network fault resiliency.
Key Features
Industry-leading Quality of Service (QoS)
» Comprehensive low-latency wirespeed QoS provides
flow-based traffic management with full classification,
prioritization, traffic shaping and min/max bandwidth
profiles. Enjoy boosted network performance and
guaranteed delivery of business-critical ethernet
services and applications. Time-critical services
such as voice and video take precedence over
non-essential services such as file downloads,
maintaining responsiveness of Enterprise applications.
Power over Ethernet Plus (PoE+)
» With the AT-x600-24Ts-POE and POE+, a separate
power connection to media endpoints such as IP
phones and wireless access points is not required.
PoE+ provides even greater flexibility, as it is capable
of connecting devices that require more power (up
to 30 Watts), for example tilt and zoom security
cameras. Diagram 1 shows an example of PoE+
power provisioning.
Link Layer Discovery Protocol–Media Endpoint
Discovery (LLDP–MED)
» LLDP-MED extends LLDP’s basic network endpoint
discovery and management functions. LLDP-MED
allows for media endpoint specific messages,
providing detailed information on power requirements,
network policy, location discovery (for Emergency Call
Services) and inventory.
Voice VLAN
» Voice VLAN automatically separates voice and data
traffic into two different VLANS. This automatic
separation places delay-sensitive traffic into a voice
dedicated VLAN, which simplifies QoS configurations.
sFlow
» sFlow is an industry standard technology for
monitoring high speed switched networks. It provides
complete visibility into network use, enabling
performance optimization, usage accounting/billing,
and defense against security threats. Sampled
packets sent to a collector ensure it always has a
real-time view of network traffic.
Terminal Access Controller Access–Control
System Plus (TACACS+) Authentication and
Accounting
» TACACS+ provides access control and accounting
for network users from a centralized server.
Authentication is carried out via communication
between the local switch and a TACACS+ server,
to check the credentials of users seeking network
access. Accounting enables user sessions and CLI
commands to be logged to create an audit trail for
user activity.
Optical DDM
» Most modern optical SFP/SFP+/XFP transceivers
support Digital Diagnostics Monitoring (DDM)
functions according to the specification SFF-8472.
This enables various parameters of the transceiver
to be monitored in real-time, such as optical
output power, temperature, laser bias current and
transceiver supply voltage. The x600 Series provides
easy access to this information simplifying diagnosing
problems with optical modules and fiber connections.
