Here's the scenario..... you've been tasked with a design and installation of the network infrastructure for a new location in your company. For the purposes of this question your choices for equipment at the new site are between Cisco and Nortel and ?? (routers, switches, hubs, etc.) .... and the network backbone will be DS3 bandwidth with connectivity to other company locations (WAN). Note: you can substitute OC3 bandwidth if it's more applicable to you .... but realize it changes the network equipment configurations for the scenario somewhat due to the application of SONET technology.
For a general philosophy ..... when you need business critical spend the money and make it perfect (Cisco). When at the edge and not business critical, (e.g. you can afford a little downtime if needed) buy solid products that compete directly with Cisco but cost a bit less.
In one case a friend uses HP at the edge and in wireless situations where uptime is not critical. They use Cisco at the core and with wireless where uptime is essential. All that being said, the HP performs just as well, costs about 25%-50% less and has a lifetime guarantee. So to answer the question, in this case I would suggest vendor three (HP) for all the switches, hubs, etc... and Cisco at the core, but if you only have two choices, then really I think you only have one, Cisco. They're the biggest in the U.S. for a reason.
Here's a tip ..... take a look at the ProCurve product line from HP. Another friend recently switched from a mix of Cisco and Netgear to all HP and had no failures. When they needed support, their question was answered the same day from a very knowledgeable service representative. They did have one piece of equipment that was DOA but had a replacement the next day.
As far as backbone connectivity - the Cisco MGX 8800 Series switch is a superior product to the Nortel 15K WAN switch,.but that is only aplicable if you are using ATM or FR as a layer 2 transport protocol in the core. If you are using MPLS or some other protocol over IP I would suggest one of the Cisco 12 K routers running IOS XR - Nortel dosent even have a comptable product (Juniper however does but that is outside the scope of this discussion.
The difference between Cisco HTTS support and Nortel Support is night and day - that should influence your decision right there.
As far as LAN switching - the Cisco 6500 Catalyst platform is the winner hands down against the Nortel 8600. Thee 8600 is easier to configure but is simply not for the enterprise never mind a carrier class soloution. The 6500 is faster, but much more complex, but out performs the 8600 and is infinitely more flexible as far as module options. The 6500 series also has the edge as far as max number of Gig-E ports.
As far as hubs - get a switch or otherwise segment the broadcast domain.
If I were looking for a voice switch or anything capable of Connecting with the world of TDM voice, I would go Nortel Cisco ... If these were my only two options.
Although Nortel has loud equipment, policies and procedures are not very customer friendly.
Cisco has a better support the needs of data-centric, I would definitely go with Cisco.
If I were building a VoIP network, should I use for my core of Cisco's routing, but I would like for my Cisco softswitch and Nortel Media Gateway.
Now supports NortelMPLS networks and has been engaged in supporting standardization in MPLS before 1998.
A recent article shows that the Nortel ERS 8300 bests the Cisco 4500 ...... showing between 75%-301% higher forwarding rate and 12% greater power efficiency.
Of course, there's the fact that the New York Stock Exchange runs on a Nortel data network (4 year old Nortel press release).
While I feel I could probably spec out a dozen network designs that would lean towards Nortel, there are clearly good reasons to go Cisco, such as if you implement a Cisco Call Manager. Likewise, there are reasons for which you would clearly choose Nortel (being power efficient is one of them).
I will opine that you well always get a sub-optimum outcome if you select a vendor first and sort out the product selections and configurations subsequently. Unless you have almost no time to do so, write up a specification which everyone except Americans know as a request for tender and issue it to the suppliers concerned, and I don't see why you wouldn't include Avaya and others in there as well. Word the specifics definitively (e.g. the system shall be able to operate for a minimum of four hours following the loss of mains power. Comply/does not comply/partially complies), include a scope of works and get vendors to respond with compliance statements, warranties (i.e. FREE maintenance for six months), maintenance contract proposals and pricing. Not only can you compare the various systems feature by feature (features you have listed because they are important for your business) but it's amazing how much pricing tends to be reduced when vendors know there's genuine competition.
Regarding these two, part of Cisco's strategy is to make it very inconvenient to attempt to integrate any non-Cisco components into a Cisco network. One of your requirements could be interworkability.
Cisco is the best and the least risk for you from a long-term perspective. I have Cisco switches are found to be extremely stable, had some switches I've seen you have been for four years without a reboot. With Cisco, you also have the advantage of the excellent documentation and a lot of qualified people to support or information online. At the level of L3 Cisco switch his peers as the code used on the switch routing platforms based on their legend.
If Cisco is too expensive or if you want to diversify, look Foundry or HP. Or better yet, use CiscoYour core and L3, and distribute the HP chassis switch for user connections. HP switch chassis are similar to other manufacturer of overlapping solutions cheap, and come with a lifetime warranty and free software updates. The CLI is very Cisco-like.
Faced with a choice of two, say, Cisco, only by a corner support - support both from the point of view of the supplier, and the recruitment of qualified personnel (permanent or contract) to support in-house. CCNA / DA, CCNP / DP, CCIE - thestreets are littered with them, but Nortel-accredited engineers are few and far between, and consequently a more expensive commodity.
In terms of features, functionality and performance, I would say it was too close to call, that specific model ranges would have to compared directly (port densities, PoE and multi-Gbps support for example). Besides Cisco, Nortel, and HP you could also make various cases for more cost-effective solutions from the likes of Alcatel-Lucent, Huawei, Foundry etc.....
To boil it all down ..... this is a religious question. Those of us who have been around long enough remember this "No one was ever fired for buying IBM". This was a marketing strategy that IBM used for quite a while. It worked! Cisco is using this same strategy now.
Cisco makes some amazing products, and they support them amazingly well. There are several other manufacturers of fabulous equipment on the market too though. HP, 3com, Extreme, and Nortel are a few. Here is what I believe. 3com and HP both make great equipment, Extreme equipment is on par with Cisco as far as capabilities, and Nortel is good.
I love the 3com 5500 series stackable switches, and they are only about ½ the price of comparable Cisco switches. HP also has great stackables, but I don't feel the quality is quit up to par with 3com. Extreme isn't Cisco but is considered to be very high end. I believe Nortel to be an also ran.
If you need to call the factory for tech Support often buy Cisco period. Technical support is the best in the industry. They are based in a location the design and operation of a network of industry-standard protocols, to figure things out for themselves, 3Com and HP now good.
Nobody ever got fired for buying Cisco. (I hope that one day these changes, as it did for IBM. But it's still true today).
Whatever you choose, the sense of similar situations with your company ..... or if you selected and lookfor a local vendor ..... you can get help finding the right fit for local support from multiple vendors including Cisco, Nortel, HP et al at Broadband Nation.
