Extreme Fabric Connect
The VSP 4900 natively supports the Extreme Fabric
Connect technology. Based on an extended implementation
of the Shortest Path Bridging (SPB) standards of IEEE
802.1aq and IETF RFC 6329, Fabric Connect oers the
ability to create a virtualized network that simplifies
network provisioning and reduces the strain on network
and IT personnel.
Fabric Connect features supported on the VSP 4900
Series include: L2 Virtual Service Networks (VSNs), Layer 3
Virtual Service Networks, Inter-VSN Routing, IPv4/ IPv6 IP
Shortcuts, IP Multicast over Fabric Connect, Fabric Extend
and Fabric Attach Server.
Fabric Extend
The VSP 4900 also natively supports Fabric Extend that
enables it to extend Fabric Connect services over an
intermediate 3rd-party network -- whether Layer 2 or Layer
3-based. With Fabric Extend, enterprises can, for example,
connect two Fabric Connect environments (or islands) over
a Service Provider WAN, such as MPLS or Ethernet WAN.
Fabric Connect simplified provisioning and virtualization
services can then be transparently extended across the 3rd-
party network.
Advanced Layer 3 Services
The VSP 4900 Series also supports advanced Layer 3
services that enable it to satisfy conventional IP routing
deployments, in addition to its fabric-based services. Layer
3 services include IPv4 and IPv6 dynamic routing, as well as
IP multicast services.
Specific IP routing technologies supported include RIPv1/2,
RIPng, OSPFv2/v3, BGP/ BGP+ and VRF. Multicast services
include PIM-SM/ SSM, IGMP v1/v2/v3, as well as Fabric
Connect to PIM gateway. The VSP 4900 also supports
Distributed Virtual Routing (DvR) leaf services.
Power Over Ethernet
VSP 4900-48P and VSP 4900-12MXU-12XE models
oer Power over Ethernet (PoE) to address the needs of
powered edge devices. The VSP 4900-48P supports IEEE
802.3at (30W) PoE on its 48 x 1Gb ports; and the VSP
4900-12MXU-12XE supports IEEE 802.3bt (60W) PoE on
its 12 multi-rate ports. Both VSP 4900 models also support
fast PoE and perpetual PoE capabilities for faster start-up
and more continuous operation of connected, PoE-powered
end-points.
Extreme Integrated
Application Hosting
Extreme's Integrated Application Hosting leverages an
innovative combination of VSP 4900 Series operating
software and hardware features to provide extended
services without impact to switching or network
performance. Available on VSP4900-12MXU-12XE and
VSP4900-24XE models, this flexible and open solution
enables organizations to run a Guest VM on the VSP 4900
system. Organizations can then use the Guest VM to deploy
their choice of Extreme-provided or third-party application/
tools for real-time visibility or to meet specific business
or operational needs across the network. This can help
improve network visibility and performance, while reducing
operational costs.
MACsec Link Encryption
The VSP 4900 supports IEEE 802.1AE MACsec on its
access ports, as well as on its modular uplink ports. MACsec
is a hop-by-hop security capability which encrypts/
decrypts packets between connected switches or devices.
As a link-only encryption, the switches can still apply
services to the packet, such as policy or QoS, without
compromising the security of packets across the link. With
support for both 128-bit and 256-bit Advanced Encryption
Standard (AES) support, the VSP 4900 provides the most
secure link encryption.
VIM Options for Flexible Uplinks
The VSP 4900 supports Versatile Interface Modules (VIM)
for its uplink ports and has a single VIM slot that can be
optionally used for this purpose. VIM options include 2
and 4-port modules that support 10Gb, 25Gb and 40Gb
data rates.
Management
The VSP 4900 can be managed in a variety of ways. Simple
on-box management functions are delivered by a web-based
GUI and a generic CLI is available for manual configuration.
ExtremeCloudTM IQ along with Extreme Management
Center (XMC) also provide a comprehensive unified
management capability with a consolidated view of users,
devices and applications for both wired and wireless
networks. Remote provisioning lets one quickly bring new
VSP 4900 switches online and a granular view of devices
ports and users enables ecient inventory and network
topology management.
