Summary
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 Ethernet and 10GbE switching devices in
their networks need guaranteed interoperability 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 interoperability with other switch brands.
N
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 Networks, 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 Protocol (VRRP) and Jumbo Frames.
Tests were conducted in August 2008 in
Santa Clara, CA at Ixia’s iSimCity lab
facility.

Executive
Summary
know which devices can maintain their interoperability with
different standardized functions.
NEC switches demonstrated broad interoperability with 19 other
switches for advanced
LAN and routing functions at Layer 2 and
Layer 3.
Engineers tested 20 switches
from eight vendors to determine
the various levels of interoperability offered.
In a world of everevolving standards and
tight budgets, network
managers searching for
new equipment need to
know that the switches
they purchase are interoperable with their current infrastructures. It is
important for managers to
In Layer 2 interoperability tests,
the three NEC switches the 1G
Intelligent L2 Switch, 1G Intelligent L3 & 10G Intelligent L3
switches consistently demonstrated interoperability with
switches from 3Com, Cisco Systems,Inc., Force10, Inc., IBM,
Foundry, Hewlett-Packard Co.
and Enterasys Networks, Inc.
(The IBM & HP switch modules
were manufactured by BLADE
Network Technologies.)
In Layer 3 interoperability
tests, the NEC switches
achieved broad interoperability
with a 3Com Switch 4800G,
seven Enterasys Networks
models tested, a Cisco Catalyst
6500, one IBM, two HP, and
four Foundry switches.
Layer 2 Functions
10/100/1000
Auto-negotiation
The NEC switches interoperated with all of the switches
tested. Devices earning this certification have demonstrated
the ability to establish the highest available speed and duplex
settings in all possible vendor
combinations.

Devices earning this certification have demonstrated the ability to detect
a failure of the Layer 2
spanning tree via the IEEE
802.1w Rapid Spanning
Tree protocol and to establish a new Layer 2 "tree."
In networks where multiple data paths exist, this
approach provides a
quicker re-establishment
of traffic paths and dramatically reduces user
downtime when compared
with the recovery mechanism of traditional 802.1D
spanning tree bridges/
switches.
For this test, the NEC
switches tested demonstrated interoperability

Layer 3 Functions
RIPv2
This test verifies that the two
NEC switches supporting Layer
3 functions (NEC 1G Intelligent
L3 Switch and NEC 10G Intelligent L3 Switch) exchange IPv4
OSPFv2
Tolly Group engineers verified
that the NEC switches exchanged routing table information via OSPFv2 with other
brand switches.
Tests show that the two NEC
switches share OSPF routing
table data with participating
switches from 3Com, Cisco,
Enterasys, Force10, HP, IBM
and Foundry.

The Cisco Catalyst 6506-E
switch and associated accessories were provided by Network
Hardware, LLC - a leading provider of used, preowned, refurbished equipment from leading
vendors like Cisco Systems, Ju-
niper Networks, Extreme Networks, Redback, etc.
Ixia provided valuable facilities and logistics support for
the Switches Interoperability
Study 2008 Tests. Ixia’s new
iSim City lab facility in Santa
Clara, CA hosted the testing,
and provided state-of-the-art
power provisioning, management and cooling that were
critical to a test of this scale.
The testbed utilized IxYukon,
Ixia's latest solution for testing
10 GbE devices and networks.
IxYukon interface modules are
used with Ixia's latest XM family of chassis: the XM12 and
XM2. IxYukon's high-density
packaging provides up to 96
ports of 10GbE in a 10U rackmount chassis and 16 ports in
a portable configuration.
