With the optional Secure Networks Policy
License, these classifications can then be used
to deny or permit access, or prioritize traffic.
Advanced Quality of Service
Broad support for Quality of Service makes
SecureStack B2 switches an ideal choice for
all types of networks, including Voice over
IP, real-time and non-real-time video, and
data-intensive applications. Extensive
classification capabilities combined with
eight priority queues per port allow the
SecureStack B2 to rate limit traffic flows
g r a n u l a r l y. Weighted Round Robin Queuing
is supported. Support for the IP Differentiated
Services Code Point (DSCP) enables the
switches to enforce requested service levels.
VLAN Support
All SecureStack B2 switches have VLAN
support, with 4,096 VLAN IDs supported and
up to 1,024 VLANs active simultaneously
in a single stack. Receive port identification
may be used to assign a user to a s p e c i f i c
VLAN. All switches support IEEE 8 0 2 . 1 Q
tagged and port-based VLANs with full
support for the GARP and GVRP p r o t o c o l s .
Extensive Security
Security is vital to all networks today and
with SecureStack B2 switches the network
is protected at the first point of entry (user
access). All SecureStack B2 switches support
u s e r-access authentication IEEE 8 0 2 . 1 x
and MAC address. The SecureStack B2 also
supports per-port multi-user authentication
with its implementation of PC + Phone
(user and IP phone). With PC + Phone the
SecureStack B2 can support MAC authen-
tication on an IP phone along with simul-
taneous user authentication via 802.1x or
MAC address per port. In addition, all
SecureStack B2 switches support V L A N s
and RADIUS. Strong authentication and
encryption for the switch is provided via
Secured Shell (SSH) and RADIUS.
Dynamic VLAN Assignment Support
Support for RFC3580 Dynamic VLAN
Assignment is included in the basic
SecureStack B2 firmware, which enables
an end user to automatically be mapped to
the appropriate VLAN upon being authen-
ticated via IEEE 802.1x. This feature is
enabled in Firmware Release 1.1, which
is now available as a free downloadable
upgrade to all SecureStack B2 customers.
Optional Secure Networks Support
Secure Networks is Enterasys’ unique
approach to enterprise networking that
integrates advanced security and manage-
ment features to centralize and automate
granular control of the entire network
infrastructure. All SecureStack B2 switches
can become full members of a Secure
Networks solution with an optional policy
license. The policy license upgrade soft-
ware will have full support for static or
port-based policies, and dynamic policies
specific to a user (per port based on IEEE
802.1x authentication or MAC address).
Secure Networks features enable SecureStack
B2 switches to fully participate in Secure
Networks Acceptable Use Policy (AUP),
Dynamic Intrusion Response (DIR) and
Trusted End-System (TES) solutions.
Robust Switch and Stack
Management
All SecureStack B2 switches are fully man-
ageable using an industry-standard command
line interface, embedded web interface,
Telnet with SSH, and SNMP management
applications such as NetSight Console
or NetSight Inventory Manager. Every
SecureStack B2 switch supports four groups
of RMON (History, Statistics, Alarms, Events)
and SNMP v1/2 and v3. Configuration files
can be edited with any ASCII editor and can
be uploaded and downloaded from a switch.
A SecureStack B2 stack can be managed as
a single network entity and only a single IP
address is required to manage the complete
stack. There is no need to download software
images to individual stack units; only one
software upgrade needs to be performed
per stack. The image will be distributed to
the individual stack members automatically.
