The boot system command and everything related to booting an IOS will not work.
Manage Cisco IOS => IOS is not in the Flash of emulated routers but you can upload it from an external source (TFTP, FTP, HTTP etc.).
(including: save, edit, upgrade, restore) => OK
Perform and verify routing configuration tasks for a static or default route given specific routing requirements => OK.
Verify device configuration and network connectivity using ping, traceroute, telnet, SSH or other utilities => OK.
Connect, configure, and verify operation status of a device interface => OK.
Access and utilize the router to set basic parameters.
Configure, verify, and troubleshoot RIPv2 => OK.
Identify and correct common problems associated with IP addressing and host configurations => OKĬonfigure, verify, and troubleshoot basic router operation and routing on Cisco devices.
Calculate and apply an addressing scheme including VLSM IP addressing to a network => OK.
Implement static and dynamic addressing services for hosts in a LAN environment => OK.
Configure, verify and troubleshoot DHCP and DNS operation on a router (using both the CLI and SDM) => OK.
Implement an IP addressing scheme and IP Services to meet network requirements in a medium-size Enterprise branch office network
Implement basic switch security (including: port security, trunk access, management vlan other than vlan1, etc.) => port security is not supported.
Interpret the output of various show and debug commands to verify the operational status of a Cisco switched network => OK.
Configure, verify, and troubleshoot RSTP operation => RSTP is not supported.
Configure, verify, and troubleshoot VTP => Almost the same but configuration is done using the vlan database mode.
Configure, verify, and troubleshoot interVLAN routing => OK.
Configure, verify, and troubleshoot trunking on Cisco switches => 802.1Q only, no ISL, no dynamic auto or dynamic desirable mode.
Configure, verify, and troubleshoot VLANs => Mostly the same but only vlan database mode is possible (not the newer global configuration mode) and the show vlan command is show vlan-switch.
Identify, prescribe, and resolve common switched network media issues, configuration issues, auto negotiation, and switch hardware failures => GNS3 cannot emulate media or hardware issues.
Verify network status and switch operation using basic utilities (including: ping, traceroute, telnet, SSH, arp, ipconfig), and SHOW & DEBUG commands => OK.
Perform and verify initial switch configuration tasks including remote access management => OK.
Let take the 640-802 CCNA® Exam Topics (Blueprint) where I only kept the config/implementation points and see what GNS3 can and cannot be used for.Ĭonfigure, verify and troubleshoot a switch with VLANs and interswitch communications Some parts like WLANs are theory only and configuration is not tested during the exam. You are right, GNS3 doesn't support all the commands but still, you can easily study most of CCNA using GNS3, more than enough to comfortably pass. I see that some of the switching commands aren't supported. Sorry if this been asked before, but does GNS3 support all the commands that I need for the CCNA and CCNA security exams?
