How dare they remove one of the most useful commands ever! Take it easy-the command may be gone, but the functionally remains, and it's better than ever. The functionality is now included without needing the command. How? Simply include the range when using the interface command and the switch will enter interface-range mode: NX-OS NX-7K-1-Cozy(config-vlan)# int e3/1 - 2 7K-1-Cozy(config-if-range)# Slash notation supported on all IPv4 and IPv6 commands I think this is very cool, but I lament the fact that engineers who already can't do subnetting in their heads will have one more argument against learning. Ah, progress. Didn't I tell you to get off my lawn? NX-7K-1-Cozy(config)# int 3/10 NX-7K-1-Cozy(config-int)# ip address 10.255.255.2/24 Two CLI help levels From within the NX-OS CLI, you can still use the question mark to show all of the commands available at the current level. Here's a short example, which will seem fa- miliar to anyone with experience using the bash shell in Unix. First, I'll use what would be called tab completion in Unix. I'll type the first few letters of a command, then press Tab to see what my options are: NX-7K-1-Cozy (config)# tacacs<TAB> tacacs+ tacacs-server This is nice because it's quick and simple. If you'd like the traditional IOS-like descrip- tion for each available command, simply use the question mark like you always have: NX-7K-1-Cozy(config) tacacs? tacacs+ Enable tacacs+ tacacs-server Configure TACACS+ server related parameters Routing configuration mostly within interfaces Router processes are still started globally: NX-7K-1-Cozy(config)# router ospf 100 However, the majority of routing protocol commands now reside within interface con- figuration mode: NX-7K-1-Cozy(config-router)# int e3/10 NX-7K-1-Cozy(config-if)# ip router ospf 100 area 0 NX-7K-1-Cozy(config-if)# ip ospf hello-interval 5 BGP commands still reside within the
