how to connect switch in access layer switch ?

hi all

our topology is that, core is 6500 which's one module is 1g and it's port is set vlan  directly use one 1G utp cable (only one cable)

connect to 2960s-48T on each floor.

ex.

interface gigabitethernet 5/9

switch  mode access

switch vlan 9

interface gigabitethernet 5/10

switch  mode access

switch vlan 10

 

  Every floor is only one vlan. ex, 10f is all vlan 10  and 9f is all vlan 9.

there are one 2960S-48T and five 2960-24T  on each floor.

how to connect these switches effectlvely?

a. one by one

2960s-48t->2960-24t->2960-24t->2960-24t>2960-24t

b. one to many

2960s-48t ->2960-24t
          ->2960-24t
          ->2960-24t
          ->2960-24t

          ->2960-24t

thanks

As Reza suggested, connecting

As Reza suggested, connecting all the switches directly to 6500 is the best way to do it.

By this you don't have a single point of failure. I.e if one of the access swithches fail , the other are not impacted.

But the downside of this design is you will be using a lot of ports on 6500. 6 ports per floor.



Then second option is to have 1:Multiple connection.

Connect the 2960-48 to 6500 with a port-channel for redundancy of uplink ports.

Connect the rest of the switches to 2960-48.

 

Example.

 

650=====Po===2960s- 48t ----->2960-24t
                                                    - >2960-24t
                                                    ->2960-24t
                                                     ->2960-24t

                                                      ->2960-24t

Hi,Just connect every device

Hi,

Just connect every device directly to the 6500

2960s-48t->6500

2960-24t->6500

and so on

Of course, a better design would be to have a second 6500 for redundancy and connect each switch to both 6500s.
