Ullal's blog followed one by Arista director Dan Scheinman, a former Cisco counsel, charging Cisco with attempting to resort to the same tactics legacy vendors used in the 1990s to stall Cisco's momentum, and questioning the timing of the suits.
Separately, Chambers said he wasn't critical of the Open Compute Project when he said almost 18 months ago that the open source hardware group had "weaknesses" that Cisco could exploit through solutions better tailored to specific customer needs. He also didn't answer questions on why Cisco now joined the group, whether it would offer an OCP switch, and if that switch would be a current OCP design or a Cisco OCP submission.
"We're growing our high-end switching gaining market share," Chambers said. "We will compete against merchant silicon with services, with architectures. We will allow software to run across platforms over time. We will prioritize that a step at a time," adding that the service provider market may be the initial target.
Cisco rival Juniper Networks recently announced that it would offer an OCP switch running its Junos operating system.
