Switch model question

We have a CISCO model WS-C3750G-48TS-E and are replacing it with a WS-C3750E-48TD-S.  Can someone briefly explain the differences with the two models?

Thank you,

Charlie

Thanks Jon. As always you are the answer man! I assume that in your response when you refer to the notable differences between the 3750 (without a letter) you are referring to the 3750G when comparing it to the 3750E right?  The model that we are replacing is a WS-3750G-48TS-E.  The model we are replacing it with is a WS-3750E-48TD-S.

Thanks again,

Correct, the 3750G-W8TS is a 3750 switch compared with the 3750E switch which is the newer model with the greater throughput etc. Note that you can run both 3750 and 3750-E in the same stack but it will revert back to Stackwise rather than use Stackwise+ which supports greater throughput but can only be used if the whole stack is comprosed of 3750-E switches.

Cisco   Catalyst 3750G-48TS
    48 Ethernet 10/100/1000 ports and 4 SFP ports

Cisco Catalyst 3750E-48TD

     48 Ethernet 10/100/1000 ports and 2 X2 10 Gigabit Ethernet uplinks

However, apart from the differences in fiber connections there is also the difference between the 3750 and the 3750-E switches ie. from the 3750-E Q&A -

Q. What are the notable differences/features between the Cisco Catalyst 3750-E and the Cisco Catalyst 3750?

A. The differences are as follows:

• Cisco Catalyst 3750-E provides a true line-rate (nonblocking) Gigabit Ethernet to the desktop solution with two line-rate 10 Gigabit Ethernet uplinks.

• The Cisco Catalyst 3750-E is a stackable switch, and it is backward compatible and stacks with the existing Cisco Catalyst 3750 family switches.

• The Cisco Catalyst 3750-E has a backplane switching ASIC, which also makes forwarding decisions, to help the switch perform wire-rate local switching.

• The Cisco Catalyst 3750-E supports dynamic a pluggable module that converts a 10 Gigabit Ethernet slot into a slot that can fit 2 Gigabit Ethernet ports. This allows for easy migration for customers moving from Gigabit Ethernet uplinks to 10 Gigabit Ethernet uplinks.

• The Cisco Catalyst 3750-E supports hot-swappable power supplies.

• The Cisco Catalyst 3750-E supports jumbo frame routing and increases the frame size to 9216 bytes.

• The Cisco Catalyst 3750-E supports uncompressed IPv6 address tables. This allows the software to program the full IPv6 address in the hardware. In addition, equal cost routing for IPv6 uses the uncompressed IPv6 address.

• The Cisco Catalyst 3750-E supports destination stripping of unicast packets.
