Stupid switch question.

I'm sure the answer to this is simple, but it's not clearly defined in the CBT Nugget videos or the Cisco Press ICND1 book.

For example, in the videos, Jeremy gives the example of the help command. For instance, a "c?" will display all commands that begin with c.

However, in global config mode when I'm trying to assign the vlan 1 interface an ip, an "ip?" just returns "ip", and "ip ?" returns a list of ip interface commands, but NOT "ip address".

What gives with this? Why will it not show me the "ip address" command?

    You have to be in interface configuration mode to assign an IP address to the interface not global configuration mode. The "?" only gives you commands relevant to the mode you are currently in.

    I was in interface config mode, specifically trying to configure vlan 1.

    Eh, I wrote global config mode in my first post. Sorry... icon_confused.gif

    It's not that pressing, I just wanted to be aware if there were certain cases where the question mark would not list a command if you didn't know the entire thing, since according to the videos and the book, the help is designed for that purpose.

    Works fine for me:

    Switch>enable
    Switch#conf t
    Enter configuration commands, one per line. End with CNTL/Z.
    Switch(config)#int vlan1
    Switch(config-if)#ip ?
    Interface IP configuration subcommands:
    <snip>
    address Set the IP address of an interface
    <snip>

    Are you entering:

    Switch(config)# interface vlan 1

    Switch(config-if)# ip ?

    This should give you the option of ip address.

    This isn't a sim is it?

    Probably is a sim

    Here's the screen cap from my 2950

    Sw2950#conf t
    Enter configuration commands, one per line. End with CNTL/Z.
    Sw2950(config)#int vlan1
    Sw2950(config-if)#ip ?
    Interface IP configuration subcommands:
    access-group Specify access control for packets
    accounting Enable IP accounting on this interface
    address Set the IP address of an interface
    broadcast-address Set the broadcast address of an interface
    dhcp Configure DHCP parameters for this interface
    directed-broadcast Enable forwarding of directed broadcasts
    helper-address Specify a destination address for UDP broadcasts
    local-proxy-arp Enable local-proxy ARP
    mask-reply Enable sending ICMP Mask Reply messages
    mtu Set IP Maximum Transmission Unit
    probe Enable HP Probe support
    proxy-arp Enable proxy ARP
    rarp-server Enable RARP server for static arp entries
    redirects Enable sending ICMP Redirect messages
    route-cache Enable fast-switching cache for outgoing packets
    security DDN IP Security Option
    unnumbered Enable IP processing without an explicit address
    unreachables Enable sending ICMP Unreachable messages
    verify Enable per packet validation

    Sw2950(config-if)#


    Sims can save you money, but there's nothing like the real thing

    The IOS on your 2950 is pretty old and you should upgrade it.

    What does "ip ?" show then?

    According to the 2950 Command Reference Guide 12.0 5.2 the command is supported.

    I'd be surprised if you couldn't set the IP address of your management interface on a 2950 :)

    I see exactly what your problem is. The issue is the space between "ip" and "?".

    If you type something followed by "?", no space in between, it will list every single word that begins with what you typed. Since "ip" is already a complete single-word command, "ip?" will list "ip" because "ip" is the only command word that begins with "ip."

    Now if you type something followed by a space and "?", you are saying "What I've typed is an unambiguous command. What is the next argument?" In your example, there are many sub-commands after ip and they're all listed.

    Try these to make sure you're clear:

    ip a?
    ip a ?
    int?
    int ?

    /usr already did that.

    /usr,

    Is there already an IP address configured on VLAN 1?

    I'm not familiar with IOS releases, but could MAINTENANCE INTERIM SOFTWARE be related to the limitation? Mine all run RELEASE SOFTWARE.
