NEW YORK ( TheStreet) -- Shares of Cisco ( CSCO) have been down by as much as 12% since the company reported its fiscal fourth-quarter earnings results and are still under pressure. The Street, which has taken a "wait-and-see" approach towards Cisco, continues to show a lack of confidence in its management. While I don't necessarily have a problem with that, I don't believe investors who have taken only a cursory look at the company's performance truly understand what Cisco has been trying to do.Take, for instance, analyst Kulbinder Garcha of Credit Suisse, who recently initiated coverage of the stock with an "underperform" rating. Garcha noted that Cisco's software-defined networking (SDN) strategy will "ultimately threaten the oligopolistic structure and superior levels of profitability seen in switching and routing." The stock price fell 1% on that report alone. Garcha continued: "While the company aims to offer an SDN platform, we expect this product evolution to shrink gross margins. While the company aims to grow its services base, this is unlikely to be a sufficient offset." JNPR) and F5 ( FFIV), the entire sector has underperformed due to shrinking enterprise budgets. I've spoken about this on more than one occasion. To counter the weak spending environment, Cisco resorted to "aggressive discounting" of some of its gear. As a consequence, though, margins took hit, to the tune of a 1% decline. But it's no cause for panic, especially since Cisco continues to beat or reach the upper-end of its guidance on every other metric that matters. In Garcha's argument, I understand why it's prudent to cite margins as an area of caution. But for a company the size of Cisco that's still amassing $4 billion in operating cash flow, it's a bit overblown The other thing that struck a chord with me was that Garcha suggested that Cisco's SDN strategy will "threaten" its routing and switching business. Essentially, Garcha is trying to preserve Cisco's legacy hardware business, while management has been working hard to transition the company out of that mindset. It's not going to happen overnight.
