Layer 3 vendors debate By Adam Gaffin Network World Fusion, 10/22/98 Atlanta - Switching vendors took potshots at each other and debated the nature of Layer 3 in a showdown today at NetWorld+Interop. The debate, sponsored by Network World, pitted seven vendors against each other: Nortel (Bay), Cabletron, Cisco, Extreme, Foundry and Packet Engines. "It's clearly fashionable these days to call anything that's fast a Layer 3 switch,'' said Cisco's Jayshree Ullal. She declared: "Contrary to public belief, neither am I a gorilla nor do I weigh 800 pounds.'' Questions to Cisco and other vendors, however, often focused on their marketing claims, in particular about packet throughput and backplane speed. Ullal acknowledged the Catalyst 8500 is more expensive than other Layer 3 switches, but said it has more functions and services. She said the Catalyst 2926 is more directly comparable to other switches on the market, in the $500 to $600/port range. Ullal asked P.G. Menon of Cabletron to explain "the contradiction" in a product lineup that includes both virtual LAN and Layer 3 products." Menon said there is no contradiction. While acknowledging that VLANs were oversold in the past, he said there is still a place for them - to support legacy protocols, such as IPX. He said users building new networks should ask themselves whether it makes more sense to go with straight Level 3. Nortel's Basil Alwan said the Cisco 8500 was an excellent product, but asked Ullal to explain why it didn't support access control lists (ACL) without an add-on card. "Lies, half-truths, what can I say?'' she responded. She said the 8500 does support ACLs via IOS software, but that Cisco sells an add-on to bring ACL processing up to wire speed. She said nobody's routers currently support wire-speed ACL processing natively. "Ours do,'' Alwan said of the Accelar line.
