3750X 10G uplink interfaces in access mode

[hans.velez]

Hi all,

just asking, any one knows if its possible to configure an 10G interface from a network module in a 3750 X switch in ACCESS MODE?

Hi,

What do you mean by access mode? Do you mean switchport mode access ?

[hans.velez]

Yeah,

because some one on my client staff request a 10G (optical) interface for a server on a 3750X, they sayd the 3750X had a network module for 10G. The only way that the servers works is with the 10G interface in access mode.

Yes, of course it will work. As long as you're using the port as layer 2 port it is possible.

interface TenGigabitEthernet1/1/1
 switchport 
 switchport mode access 
 switchport access vlan 40

Hi Hans,

As mention you can use Tengig port to connect to Server same configuration as normal access port on Gig interface but check SFP transceiver at switch whether it is compatible with server end  SFP.

Also if your server is is connected to Tengig port there over Subscription issue on uplink if it is 1 gig link.

In the 10G interface got the same issue for over subscription?

Hi Hans,

For instance link on which server is connected is Tegig and up link switch this is 1  gig then there would be bottle neck and performance issue when server can generate tengig of traffic but up link can only support 1 gig.
