(Are you familiar with cisconetworkassistant (CNA)? This is a free tool to help you configure Cisco devices. In this article, daviddavis will introduce you to this very easy-to-use tool and compare [blocked ads] with the previous ciscoconfig maker& amp; amp; nbsp; In Cisco's product line for small and medium-sized enterprises (SMBs), it provides you with a free tool, cisconetworkassistant (CNA), to help you configure Cisco devices. Of course, you may think that this tool aimed at small and medium-sized enterprises is not necessarily applicable to you, but remember that in Cisco terminology, & amp; quot; SME & amp; quot; It may be a fairly large enterprise, at least in my opinion. Because this tool is free, you can download it from Cisco's website. Cna supports everything from small and medium-sized routers to 6500 series catalyst switches, pix firewalls, IP phones and wireless access points. According to Cisco, CNA is ideal for enterprises with up to 250 users. Of course, I don't know how many users there will be in your network, but the number of users in your network determines which router configuration tool you need to use (maybe you have more than 250 users, so Cisco may think you should have more network management budgets, so it wants to sell you a management tool).)
