1G Intelligent L2 and L3 Switches and

10G Intelligent L3 Switch

Functionality Certification and Cooperative Interoperability Evaluation

Premise: Heterogeneous, multivendor

networks are the rule rather than the

exception. IT managers who deploy a

variety of Fast Ethernet, Gigabit Ether-

net and 10GbE switching devices in

their networks need guaranteed in-

teroperability of these switches in order

to maintain a functional network.

EC Corporation and BLADE

Network Technologies

(BLADE) commissioned The

Tolly Group to evaluate three of their

enterprise-class LAN switches for in-

teroperability with other switch brands.

Tolly Group engineers evaluated the

NEC 1G Intelligent L2 Switch, NEC

1G Intelligent L3 Switch & NEC 10G

Intelligent L3 Switch against more than

a dozen tests with switches from 3Com,

Cisco Systems, Inc., Enterasys Net-

works, Inc., Force10 Networks, Inc.,

Hewlett-Packard Co, IBM Corporation,

and Foundry Networks, Inc.

Engineers subjected the NEC switches

to advanced Layer 2 and Layer 3 tests,

including support for auto-negotiation,

802.1p/Q VLAN tag propagation,

10GbE LAN PHY Support, 802.3ad

LACP support, Rapid Spanning Tree

Protocol support, Multiple Spanning

Tree Protocol support 802.1s, RIPv2,

RIPng, OSPFv2, OSPFv3 support,

BGP4, Virtual Router Redundancy Pro-

tocol (VRRP) and Jumbo Frames.

Tests were conducted in August 2008 in

Santa Clara, CA at Ixia’s iSimCity lab

facility.
