Would it be a wise decision to invest in 4948 switch. Does any one here has any good experience of using it? If not, then I am looking for 4503 as well as its alternative [48 ports]. Any comments are welcome.

HI, [Pls Rate if HELPS]


In my Experience i would recommend Cisco 4506 Switch for your Environment.


You need to consider your Future Scalability Factors in your Environment.


Pls See link below for Comparison Chart:

Thanks buddy. Besides the scalability part, you are still not advising for 4948. Yes, I am looking for 4506, 4507R and 4503. However, keeping my budget constaint in my mind, I think 4503 w/ SUP V, 10 GE is scalable upto 72Gbps and it should work fine with one slot available to have another 48 port UTP or Fiber connectivity.

HI, [PLS Rate if HELPS]


Considering at your Budget point of view, Cisco 4948 is advisable and recommended.


Cisco 4948 Switch:

-----------------------

Cisco Catalyst 4948 offers 48 ports of wire-speed 10/100/1000BASE-T with 4 alternative wired ports that can accommodate optional 1000BASE-X Small Form-Factor Pluggable (SFP) optics


Cisco 4948 10G Switch:

--------------------------

The Cisco Catalyst 4948 10GE Switch offers 48 ports of wire-speed 10/100/1000BASE-T with 2 ports of wire-speed 10 Gigabit Ethernet (X2 optics).


INFO: With Cisco 4948 Switch you can have 48 port UTP with 4 Ports of Fiber Connectivity. Consider how many Fiber UPlink you will have your Environment.


Key Feature:

---------------

The Cisco Catalyst 4948 delivers wire-speed throughput with low latency for data-intensive applications using a 96 Gbps switching fabric with a 72 Mpps forwarding rate in hardware for Layer 2-4 traffic. Switching performance is guaranteed regardless of the number of route entries or Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture allows for increased scalability and performance.

Hi


It really depends on what you are using the switch for. The 4948 is really a data centre switch for connecting servers at wire speed. It is not modular so there is no upgrade path other than purchasing a new switch.


The 4500 is modular and if you think you may need more capacity in the future i would go for a 4507 if you have the space. The chassis cost is never that much compared to the modules that go in it.


To be honest i would say it should be a choice between 4500 or 3750 switches which can be stacked to allow futher port capacity.


You only need to look at the 4948 for sheer throughput terms.
