c3750e-ipbasek9-tar.122-58.SE2.tar                         Cisco Catalyst 3750E-48PD-E Switch

c3750e-ipbasek9-tar.122-55.EY.tar                           Cisco Catalyst 3750E-48PD-EF Switch

    Cisco Catalyst 3750E-48PD-S Switch

    Cisco Catalyst 3750E-48PD-SF Switch

    Cisco Catalyst 3750E-48TD-E Switch

    Cisco Catalyst 3750E-48TD-S Switch

Need suggestion to upgrade IOS

Hi Aman,

122-58 is pretty good, but you should read the release notes to make sure there are no major bugs.  If your switches are stacked, you can use the .tar file to upgrade.  If they are not stacked than you can use .bin file to upgrade.

If you are planning to provide a vlan per floor than you can use the floor number:

example:

1st floor 10

second floor 20

3rd floor 30

and so on.
