Hi

3750's

From the 3750 FAQ

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.

6500 chassis

6500-E chassis allows the chassis to support and draw more power ,greater than 4000W, to support the more recent linecards.
