Can you tell me what is wrong with this logic? I know my interface Regex is good, as this works fine without the prerequisite check. This should return any port 1/0/1 - 1/0/24 that does NOT have switchport mode trunk, has the + commmands below. When I do a check, it just returns that I do not have any of the prerequisites...should return "compliant"

PreReq:

Parent: None

Prereq: None

Prereq?: Checked

Submode: interface [#.*/0/([1-9]|1[0-9]|2[0-4])#]

CLI:

- switchport mode trunk

Check:

Parent: PreReq

Prereq: PreReq

Prereq?: Not Checked

Submode: Blank

CLI:

+ switchport mode access

+ switchport nonegotiate

+ spanning-tree portfast

+ storm-control broadcast level 1.00

+ storm-control multicast level 1.00

Running LMS 3.2 now with RME 4.3.1, still hitting this bug(at least a variation of it)

My (current) specific complaint is as follows:

Prerequisite:

Submode:

     interface [#.*#]

Checks:

     +switchport mode trunk

     -[#channel-group.*#]

In theory, this is to match all trunk ports that are not a member of a port channel. In testing, this matches ALL trunks(basically ignoring the negative statement).

In further testing, if i remove the positive statement ("+switchport mode trunk") and leave ONLY the negative check ("-channel-group") it DOES match all ports not a member of a portchannel.

So it seems this bug has been partially fixed, in that negative prereq checks DO work, just not in combination with a postivie check.

Is there a current bug logged? Or better yet, is there a workaround for this?

This is CSCta80687.  The problem stems from the fact that your negative prereq uses regular expressions (this bug only happens in certain circumstances).  There is currently no fix or workaround.  It will be fixed in LMS 4.0 due out this summer.
