The history of the Cisco CLI
By Terry Slatttery
I don't think many people know the history of the Cisco CLI and the impact it has had on the industry. Other companies are emulating it, as evidenced in recent articles on the topic. Network engineers typically become experts in the Cisco CLI first, then move to other vendor gear, so it makes sense for companies to emulate it. Brad Reese, who writes for Network World's Cisco Subnet, did an article on the topic on October 5, 2007, Appealing to CCIEs, hardware vendors copy Cisco's CLI and NetFlow to get into Cisco accounts.
