 Re: 3750G-TS-S vs 3750G-TS-E


3750G-TS-S is a switch with standard image which supports basic Layer3 features like RIP 1/2 and static routing only.

3750G-TS-E is a switch with enhanced image which supports ehanced layer 3 routing features like EIGRP,OSPF, BGP, IS-IS, Policy based routing.

Please see the differnce below:

What is the difference between 3750g and 3750

As per your question,G means all ports are Gigabitport.

e: Cisco 3750-X vs Cisco 3750G

Differences between 3750G and 3750X:

The 3750G uses stackwise and 3750X uses stackwise+. With Stackwise, EVERY packet has to go across the stack ring even if the destination port is on the local switch. With Stackwise+, the switches can do local switching.

Also, if you mix STackwise and Stackwise+ capable switches in the same stack, the Stackwise+ switches will still be able to switch locally and the Stackwise switches must continue to operate the same way.

Here's a link:

Cisco 3750 vs 3560


What is the difference between the Cisco 3750 and 3560?  What about the 3750E vs 3750X?  These question comes from clients time and time again.  Here are the answers you need.

The main difference is that the 3750 supports Cisco StackWise, i.e. creating one large virtual switch out of multiple chassis.  The 3560 has a "cluster" feature which while it sounds close, just means that you can control multiple switches from a single one.

"Timed out" means that the ISP is blocking the port.

https://serverfault.com/questions/273600/ping-from-specific-network-adapter-on-windows

syntax:
From Windows 7 (Version 6.1 Build 7601: Service Pack 1) ping /?

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
        [-r count] [-s count] [[-j host-list] | [-k host-list]]
        [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name


Options:
-t             Ping the specified host until stopped.
               To see statistics and continue - type Control-Break;
               To stop - type Control-C.
-a             Resolve addresses to hostnames.
-n count       Number of echo requests to send.
-l size        Send buffer size.
-f             Set Don't Fragment flag in packet (IPv4-only).
-i TTL         Time To Live.
-v TOS         Type Of Service (IPv4-only. This setting has been deprecated
               and has no effect on the type of service field in the IP Header).
-r count       Record route for count hops (IPv4-only).
-s count       Timestamp for count hops (IPv4-only).
-j host-list   Loose source route along host-list (IPv4-only).
-k host-list   Strict source route along host-list (IPv4-only).
-w timeout     Timeout in milliseconds to wait for each reply.
-R             Use routing header to test reverse route also (IPv6-only).
-S srcaddr     Source address to use.
-4             Force using IPv4.
-6             Force using IPv6.

Example:
dos> ping 192.168.100.1 -S 192.168.200.1

use CAPITAL S to specify source address from which ping will originate. in the above example, two network cards are placed in the windows computer. normal ping originates from 127.0.0.1 (local host IP). In the example the ping originate from 192.168.200.1
