Hi there,

 

Does anyone have some good examples on how to use wildcards in apply-groups?

 

http://www.juniper.net/techpubs/en_US/junos11.2/topics/concept/junos-cli-wildcard-characters-configuration-groups-usage.html

 

Here, we have the documentation for wilcard matching..., question marks, character classes, etc.

 

However, first of all, I can not type the question mark, since it brings up the "help" command completion... Here are a couple of examples on what I would like to type, but cannot:

 

<3[023]??>

<3[023][0-9][0-9]>

 

Does anyone know how to type the question mark, or how to write several character classes?

 

Thanks.

Hi PerG,

 

Just enclose your regular expression within double quotes, like this:

 

"<ge-[0-3]/?/*>"

 

..that should do the trick.

Hi,

 

I am actually working unit numbers, and not interface names, although that is not very relevant.

 

First, it was clearly the double quotes and the / escape character I was missing - to be able to type a question mark at all. However, even with that, I can not get the question mark to catch:

 

if I want to match 3303, 

 

"<3*03>"will work

"<3/?/03>"does not work

"<3/?03>"does not work

 

Any idea?

Any documentation?

Neither does this:

 

 "<3[023]/?/*>"

Hi PerG,

please show us your group config and configuration fragment you want to match. Matching just unit number or full interface name ?

"<3[023]/?/*>" may be a part of interface name. It won't match any interface name nor unit number. You need to match whole item/word.

Hi,

 

It is actually the full string:

 

GROUPNAME {
interfaces {
<*> {
unit "<3[023]*>" {

 

And the idea was to match that on any interface name, for units with 4-digit unit numbers of 3x.., where x is 0, 2 or 3.

 

This works:

"<3[023]*>"

but it obviously does not restrict the unit string to be 4 digits only.

hi PerG,

 

"<3[023]>" will just match units 3x, where x is 0,2 or 3

"<3[023][023][023]>" is the wildcard you need:  units with 4-digit unit numbers of 3xxx, where x is 0, 2 or 3

 

From the documentation URL: A character class matches any of the characters between the square brackets - any single character from the class, not any string of the characters.

Thanks for the input. However, as I mentioned in the first post I tried:

 

<3[023][0-9][0-9]>

 

and it did not work...

hi,

 

"<3[023][0-9][0-9]>" will match 3xxx, where x is 0, 2 or 3, sure. Please re-test.

 

Just did the simple test:

 

admin@s1# show groups u3x00 
interfaces {
    <*> {
        unit "<3[023][0-9][0-9]>" {
            description u3x00;
        }
    }
}

[edit]
admin@s1# show interfaces apply-groups                     
apply-groups u3x00;

[edit]
admin@s1# show interfaces fe-0/0/4  
vlan-tagging;
unit 333 {
    vlan-id 333;
    family inet;
}
unit 3023 {
    vlan-id 3023;
    family inet;
}
unit 3333 {
    vlan-id 3333;
    family inet;
}

[edit]
admin@s1# show interfaces fe-0/0/4 | display inheritance 
vlan-tagging;
unit 333 {
    vlan-id 333;
    family inet;
}
unit 3023 {
    ##
    ## 'u3x00' was inherited from group 'u3x00'
    ##
    description u3x00;
    vlan-id 3023;
    family inet;
}
unit 3333 {
    ##
    ## 'u3x00' was inherited from group 'u3x00'
    ##
    description u3x00;
    vlan-id 3333;
    family inet;
}

BTW in one post above you describe "/" as 'escape character'. It's not true, the "/" is regular character in wildcard context.

Old thread, but maybe someonewill still see this.

 

I have a smiliar challenge.I a also trying to match a wildcard on unit numbers, but I want to match all unit numbers between 0 and 4999.  I cant figure out how to get it done in one statement.

 

"<[0-4][0-9][0-9][0-9]>" is close, but only matches 4 didgit numbers, so it essentially matches 1000-4999

 

Using two  stanzas as follows works, but is clunky
