Resilient
VCStack provides fast failover for uninterrupted network service.
Sophisticated high availability features ensure traffic flow continues even
during outages.
VCStack
You can create a VCStack with two units using the two high speed stacking
connectors on the rear of the chassis. Each connector can provide 80Gbps
of stacking bandwidth. VCStack provides a highly available system where
network resources are spread out across stacked units, reducing the impact
should one of the stacked units fail. You can aggregate switch ports on
different units across the stack to provide excellent high availability.
Control Plane Prioritization (CPP)
Ensure maximal performance and prevent network outages with CPP.
CPP prevents the Control Plane from becoming flooded in the event of a
network storm or Denial of Service (DoS) attack.
Scalable
Add more XEMs as your network grows. Add more devices to a VCStack to
increase port density and resiliency without increasing management complexity.
Our high speed XEMs provide both copper and fiber connectivity, delivering
the ultimate in flexibility. XEM options are:
• AT-XEM-1XP - 1 x 10GbE (XFP)
• AT-XEM-12S - 12 x 100/1000BASE-X SFP ports
• AT-XEM-12T - 12 x 10/100/1000BASE-T (RJ-45) ports
XEMs are also compatible with the x900-24X and x900-12XT/S. All XEMs
provide non-blocking performance. XEMs are ideal for aggregating gigabit to
the desktop or for gigabit uplinks from Fast Ethernet switches.
Reliable
Hot-swappable XEMs, redundant hot-swappable PSUs and replaceable fans
ensure no network interruptions during maintenance or reconfiguration.
10GbE expansion modules and hotswappable XFPs provide high-speed, high-
capacity fiber uplinks.
The SwitchBlade x908 switch operates with one PSU - installing a second
PSU provides redundancy. Internal PSUs eliminate the need for an external
Redundant Power Supply (RPS) that occupies valuable rack space. Built-in
redundancy guarantees the continued delivery of essential services.
The SwitchBlade
®
x908 also features front-to-back cooling, maximising its reliability.
High-performing
Non-blocking architecture and superior QoS ensure wire-speed delivery of
all your critical IPv4 and IPv6 traffic.
Ethernet Protected Switched Rings (EPSR)
EPSR and 10 GbE modules allow the SwitchBlade x908, with a number of
x900 switches or iMAPs, to form a protected ring with 50ms failover - perfect
for high performance at the core of Enterprise or Provider Access networks.
Wire speed switching
The SwitchBlade x908 has fully non-blocking switching on all ports, so IPv4
Layer 2 switching and Layer 3 routing occur at wire speed. This is ideal for
high-end server deployments, and, when combined with a large L3 route table,
for aggregating gigabit connections.
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. Enjoy boosted network performance and guaranteed
delivery of business-critical Ethernet services and applications. Time-critical
services like voice and video applications take precedence over non-essential
services like file downloads, maintaining responsiveness of Enterprise
applications. Unmatched QoS accuracy is achieved with a bandwidth limit
resolution down to 1Kbps, which is ideal for precise control of Enterprise
desktop-based VoIP applications.
Easy to manage
The industry standard CLI reduces training requirements, and each VCStack
appears as one virtual chassis with a single IP address to simplify management.
The SwitchBlade x908 runs the advanced AlliedWare Plus™ Layer 3 Fully
Featured Operating System delivering a rich feature set and an industry-
standard CLI.
Using VCStack allows stacked devices to appear as a single node on the
network, greatly simplifying your management.
Administrators can choose from a range of secure remote management
options including SNMPv3 and SSH.
Triggers automatically run user-defined scripts when specified events occur.
Loop Protection detects and warns you if a network loop occurs. You can also
specify remedial action, such as shutting down the affected ports.
Secure
Advanced security features protect your network - from the edge to the core.
802.1x User Authentication
The SwitchBlade x908 has 802.1x user authentication. This is essential for
Enterprise networks needing to prevent intruders from accessing their
network. Other security features include Private VLANs.
Network Access Control (NAC)
NAC allows for unprecedented control over user access to the network, in
order to mitigate threats to network infrastructure. The SwitchBlade x908
supports NAC by using 802.1x port-based authentication in partnership with
standards-compliant dynamic VLAN assignment to enable a user’s adherence
to the network’s security policies to be assessed, and either authentication
granted or remediation offered.
Allied Telesis NAC also supports alternatives to 802.1x port-based
authentication, such as web authentication to enable guest access, and
MAC authentication for end points that do not have an 802.1x supplicant.
Furthermore, if multiple users share a port then multi-authentication can be
used and a Guest VLAN (also known as Default VLAN) can be configured to
provide a catch-all for users without an 802.1x supplicant.
As well as supporting a RADIUS client for remote authentication, the
SwitchBlade x908 has a built-in RADIUS server for local authentication.
