Excel Formula / data mining issue

Hi Guys,

Here's the situation. I pull data off a switch twice a day, i need to figure out which ports are dynamically assigned to which vlans on a regular basis.

so my data is port number: which is 1/1 format and vlan: 1505 or 1501 etc..

So if it is in an excel sheet it will look like below, I need to match columns B/D/F ....etc,, if they match then i need to write the vlan info from C/E/G into column A...

Here's the catch, In column A i want the most reoccurring value from C/E/G  and to add to the problems sometimes the columns dont match up... so if it could be some kind of search function it would be fantastic, otherwise i have to manually go through and line them up. like in the bottom example.

   A      B         C                           D       E                                      F               G
1      1/1      1501 (green)            1/1      1501 (green)
2      1/3      1501 (green)            1/3      1501 (green)
3      1/5      1501 (green)            1/5      1501 (green)
4      1/6      1501 (green)            1/6      1501 (green)


If the rows dont match for the port numbers..........

  A      B         C                           D       E                                      F               G
1      1/1      1501 (green)            1/1      1501 (green)
2      1/3      1501 (green)            1/3      1501 (green)
3      1/5      1505 (green)            1/4      1504 (green)
4      1/4      1504 (green)            1/5      1505 (green)

Dear P,

I did see where it went wrong, so I changed a bit the macro and now it should be working fine.
You did not say however if it finds just one item if it should kist that item also, it now does...

Hi

I appear to be getting the same output in all of column A... regardless of the C/E column data

I tried it, you can see my data, if it fiends something appearing more times it will show this, in row A I tried it with 3 times 1502 and it showed 1502?

Was this not what you had in mind?

Not sure if i'm explaining it to well, or if indeed it can be accomplished with Excel...

I have attached a copy of what i'm doing,,,, so on every day 22nd 23rd 24th etc....i will paste in the details taken from the switch "port number and Vlan"

i want to some how verify the port numbers match the previous day or the first day or even just search for the port number and then write the vlan result somewhere... maybe there is a better way of doing it.. like writing the results to a seperate sheet or something.

the ultimate goal is to get a list of port numbers with the vlan most used on it over a period of a week.

Thanks,

Dear P,

Strange, it should (and if I try it it does) keep on going until 65xxx.. or until it sees no more entry's
The macro checks for the entry's by looking in  column B with following statement:   While Cells(i, 2) > ""I Marked this statement with the text loop thru rows
So if you have a empty cell B76 or B77 it stops just there..


Kind regards

Eric
