Multiple Spanning Trees (IEEE 802.1s) and Rapid Reconvergence

(IEEE 802.1w), are fully supported. All switches support up to 16,000

addresses and have eight hardware queues per port. Ethernet Flow

Control (IEEE 802.3x) as well as standards-based Link Aggregation

(IEEE 802.3ad) are fully supported in every switch model. In addition, all

switches support Jumbo Frames (frames up to 9,216 bytes) and IGMP

Snooping v1 and v2.

Extensive Trafﬁc Classiﬁcation

SecureStack C2 switches comprise the ideal family of switches for

delivering any converged network solution. A major component for

supporting converged networks is trafﬁc classiﬁcation. All SecureStack

C2 switches deliver extensive Layer 2/3/4 packet classiﬁcation and

marking at the edge based on any of the following attributes:

• MAC address

• Physical port

• IP address

• IP Protocol

• IP ToS/DSCP marking

• TCP/UDP port

• IP subnet

The classiﬁcation can then be used to deny or permit access, or prioritize

the trafﬁc.

Advanced Quality of Service

Broad support for Quality of Service makes SecureStack C2 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 network-wide policies and eight

priority queues per port allow the SecureStack C2 to granularly rate limit

trafﬁc ﬂows. Both weighted round robin, which keeps low priority trafﬁc

from being completely starved of bandwidth, and strict priority queuing

are supported. Support for the IP Differentiated Services Code Point

(DSCP) enables the switches to enforce requested service levels.

VLAN Support

All SecureStack C2 switches have extensive 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 speciﬁc VLAN. All switches support IEEE 802.1Q VLANs, port-based

VLANs, protocol-based VLANs and tagged-based VLANs with full support

for the GARP and GVRP protocols.

Full Layer 3 Routing

All members of the SecureStack C2 switch family support static routing

in the base software, along with support for the following protocols:

• Routing Information Protocol (RIP v1/v2)

• Internet Control Message Protocol (ICMP)

• Address Resolution Protocol (ARP) & ARP Redirect

• Dynamic Host Conﬁguration Protocol (DHCP) Relay

• Bootstrap Protocol (BOOTP) Relay

With the optional Enhanced Routing License (one license per stack of

SecureStack C2s), any SecureStack C2 switch can support the following

additional protocols:

• Open Shortest Path First (OSPF)

• Virtual Router Redundancy Protocol (VRRP)

• Distance Vector Multicast Routing Protocol (DVMRP)

• Protocol Independent Multicast—Sparse Mode (PIM-SM) (future)

A total of 512 IPv4 routes can be supported in each switch. Recognizing

that interoperability with IPv6 networks is mandatory for any new

enterprise switch, all SecureStack C2 switches have the ability to

identify, prioritize, classify, and redirect IPv6 trafﬁc to an IPv6 router.

Extensive Security

Security is vital to all networks today and with SecureStack C2 switches

the network is protected at the ﬁrst point of entry (user access).

Authentication and security of end user ports can be managed at the

individual port or individual user granularity level. All SecureStack C2

switches support User Access Authentication via IEEE 802.1x, access

control lists, VLANs, RADIUS, MAC and Web-based (PWA) authentication

in the basic ﬁrmware. The SecureStack C2 also supports per-port multi-

user authentication with its implementation of PC + Phone (user and IP

phone). With PC + Phone, the C2 can support MAC authentication on an

IP phone along with simultaneous user authentication via 802.1x, MAC

or Web-based (PWA), per port.

Secure Networks Support

Traditional perimeter security is not sufﬁcient and scalable enough

to defend against today’s sophisticated threats. Secure Networks is

Enterasys’ unique approach to enterprise networking that integrates

advanced security and management features to centralize and automate

granular control of the entire network infrastructure. All SecureStack C2

switches can be full members of a Secure Networks solution. The basic

software has full support for static or port-based policies, and dynamic

policies speciﬁc to a user. Per-port authentication is based on IEEE

802.1x, MAC address, or Web-based (PWA). The C2 also supports a

mechanism that allows multiple users to be authenticated over a single

port. These features enable network managers to set Acceptable Use

Policies, Secure Application Provisioning, Secure Guest Access, Dynamic

Intrusion Response, and Trusted End System.

Robust Switch and Stack Management

All SecureStack C2 switches are fully manageable using an industry-

standard command line interface, embedded web interface, Telnet

with SSH, and SNMP management applications such as NetSight.
