No. As already mentioned above to have 10g interface, you gonna have to upgrade to 3750-E or 3750 or 3560 X series. They support 10GbE SFP+ Ports.

On 3750g, you proberbly can have max 8g by aggregating 8 ports in a port-channel.

Hello,

The maximum speed supported by each Stack cable is 16 Gbps. Since you will

have two paths in the stack, the effective speed will be 32 Gbps. Trunking

speed depends upon the type of link you are using. If you are using Gig

Links, it will be a max of 1 Gig (if you go for Etherchannel with multiple

Gig links, then it will be sum of the total bandwidth of all gig links).

Can u please tell me what is the maximum trunk speed an configure in this switch?

The 3750-E versions have the 10GB ports. http://www.cisco.com/en/US/products/ps7077/

Regarding the stacking speed just to add to above comments, when two or more switches are connected via stackwise cable, a switch fabric consisting of dual counter-rotating rings if formed, with each ring providing 16Gbps of bandwidth, resulting in 32Gbps of total bandwidth.

Just to add to that the StackWise Plus and StackWise can support up to 2 Ten Gigabit Ethernet ports per Cisco Catalyst 3750-E

Hello,

3750E and 3750X switches support 10G links. Regular 3750 does not support

10G modules. So, if you have 10G module, then yes, you can have a trunk of

10G bandwidth.
