Can an IP address be connected to a specific port on a 3 port Cisco switch on a computer? I would like to create a network map that can recognize that computers where physically located in our building based on our IP address. If a computer takes the space, then it gets a new IP address, in this way an IP address has been assigned to the physical location, and is not a MAC address or computer.

Other suggestions for being able to identify this computer are physically located, if my IP address idea is absurd,

You need an IOS that supports your switch; You should also issue DHCP with your switch Let's say you got Vlan120 in Fa1 / 0/1 and Fa1 / 0/2 . 

  IP uses DHCP client-ID client -IP IP DHCP customer-ID interface-name IP DHCP out-of-address 192.0.2.1 192.0.2.10! IP DHCP Pool VLAN120 Network 192.0.2.0 255.255.255.0 Default Router 192.0.2.1 DNS-Server 192.0.2.5 Reserved-Only Address 19.0.2.101 Client-ID "FA1/0/1" ASCI Address 192.0.2.102 Client-ID "FA1 / 0/2" ASCI

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
