Flexible Border Routing with
Internet Scale, Ultra-Deep Buffers,
MPLS and EVPN
The SLX 9640 is a very powerful compact deep buffer
Internet border router, providing a cost -efficient solution
that is purpose-built for the most demanding service
provider and enterprise data centers and MAN/ WAN
applications. The robust system architecture supported by
SLX-OS and a versatile feature set including IPv4, IPv6,
and MPLS/ VPLS with Carrier Ethernet 2.0 and OAM
capabilities to provide deployment flexibility.
High-Availability and Reliability
The SLX 9640 delivers high performance and reliability
required by the most advanced routers. It is designed for
high availability from both a software and hardware
perspective, such as a clear separation between the
control plane and data plane and redundant power
supplies and fan modules.
Modular, Virtualized
Operation System
The SLX 9640 runs Extreme SLX-OS, a fully virtualized
Linux-based operating system that delivers process-level
resiliency and fault isolation. SLX-OS supports advanced
switching features and is highly programmable with
support for REST API with the YANG data model, Python,
and NETCONF. It is based on Ubuntu Linux, which offers
all the advantages of open source and access to
commonly used Linux tools.
Strong Network Security
Security is a top concern for every network design. The
border routers are directly exposed to raw Internet traffic
and therefore can be the first defense against malicious
activity directed at your internal networks. Having multiple
layers of security enhances protection. By starting at the
border routers, you can utilize features such as BGP
FlowSpec to mitigate directed denial of service attacks
(DDoS) and advanced access control lists (ACLs) for CPU
and data plane protection of the routers themselves.
These features are critical components to your overall
multilayered security strategy.
Management
The SLX 9640 can be managed in a variety of ways.
REST, NETCONF management interface or simple
on-box management functions are delivered with
CLI for manual configuration. For centralized
management, the Extreme Management Center (XMC)
delivers a comprehensive unified management
capability. XMC provides a consolidated view of
users, devices and applications for wired and
wireless networks ? from data center to edge.
Pay as You Grow Flexibility
The SLX 9640 offers a unique procurement model with
ports on demand and capacity demand licensing. The SLX
can be purchased in a variety of available active port
speeds and combinations, thus making it more cost-
effective overpaying for all ports on the physical hardware.
If additional port capacity is required in the future, simply
apply a license to enable the ports on the fly.
