| High Availability Video Surveillance Switch

Key Features

Reliable

» Dual hot-swappable load-sharing power supplies

maximize network uptime, ensuring a resilient

solution where always-on access is required.

Allied Telesis Management Framework (AMF)

» Allied Telesis Management Framework (AMF) is a

sophisticated suite of management tools that provide

a simplified approach to network management.

Common tasks are automated or made so simple that

you can achieve the every-day running of a network

without the need for highly-trained, and expensive,

network engineers. Powerful features like centralized

management, auto-backup, auto-upgrade, auto-

provisioning and auto-recovery enable plug-and-play

networking and zero-touch management.

VCStack

( Virtual Chassis Stacking)

» Create a VCStack of up to four IX5 units with 40Gbps

of stacking bandwidth to each unit. 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.

Long-distance Stacking

» Long-distance stacking allows a VCStack to

be created over longer distances, perfect for a

distributed network environment.

EPSRing

(Ethernet Protection Switched Ring)

» EPSRing and 10 Gigabit Ethernet allow several IX5

switches to form a high-speed protected ring capable

of recovery within as little as 50ms. This feature is

ideal for large IP surveillance environments.

» Super-Loop Protection enables a link between

two EPSR nodes to be in separate EPSR domains,

improving redundancy and network fault resiliency.

Industry-leading Quality of Service (QoS)

» Comprehensive low-latency wire speed QoS provides

flow-based traffic management with full classification,

prioritization, traffic shaping and min/max bandwidth

profiles. Boosted network performance and

guaranteed delivery of business-critical Ethernet

services and applications are provided. Time-critical

services such as voice and video take precedence

over non-essential services such as file downloads,

maintaining responsiveness of Enterprise applications.

Loop Protection

» Thrash limiting, also known as rapid MAC movement,

detects and resolves network loops. It is highly

user-configurable — from the rate of looping traffic

to the type of action the switch should take when it

detects a loop.

» With thrash limiting, the switch only detects a loop

when a storm has occurred, which can potentially

cause disruption to the network. To avoid this, loop

detection works in conjunction with thrash limiting

to send special Loop Detection Frame (LDF) packets

that the switch listens for. If a port receives an LDF

packet, you can choose to disable the port, disable

the link, or send an SNMP trap. This feature can

help to detect loops before a network storm occurs,

avoiding the risk and inconvenience of traffic

disruption.

Power over Ethernet Plus (PoE+)

» With PoE, a separate power connection to media

endpoints such as IP phones and wireless access

points is not necessary. PoE+ reduces costs and

provides even greater flexibility, providing the

capability to connect devices requiring more power

(up to 30 Watts) such as, tilt and zoom security

cameras.

Link Layer Discovery Protocol – Media

Endpoint Discovery (LLDP – MED)

» LLDP-MED extends LLDP 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.

Dynamic Host Configuration Protocol (DHCP)

Snooping

» DHCP servers allocate IP addresses to clients, and

the switch keeps a record of addresses issued on

each port. IP source guard checks against this DHCP

snooping database to ensure only clients with specific

IP and/or MAC address can access the network.

DHCP snooping can be combined with other features,

like dynamic ARP inspection, to increase security in

Layer 2 switched environments, and also provides

a traceable history, which meets the growing legal

requirements placed on service providers.

Tri-authentication

» Authentication options on the IX5 also include

alternatives to IEEE 802.1x port-based authentication,

such as web authentication to enable guest access

and MAC authentication for endpoints that do

not have an IEEE 802.1x supplicant. All three

authentication methods—IEEE 802.1x, MAC-based

and Web-based—can be enabled simultaneously on

the same port for tri-authentication.

Access Control Lists (ACLs)

» AlliedWare Plus delivers industry-standard Access

Control functionality through ACLs. ACLs filter

network traffic to control whether routed packets

are forwarded or blocked at the port interface. This

provides a powerful network security mechanism to

select the types of traffic to be analyzed, forwarded,

or influenced in some way.

Terminal Access Controller Access–Control

System Plus (TACACS+) Authentication and

Accounting

» TACACS+ provides access control 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 keeps a record

of commands entered during user sessions to ensure

a secure network and clear audit trail.
