I'm searching for advice regarding network equipment upgrade, as I don't have much experience with Cisco. I maintain LAN with 2 core switches (1x4500, 1x4006, 1 Cisco 3621 router on the stick, 16 access switches including 2950, 3650 units, 10 VLANs configured). My priority is to upgrade both core switches, so I'd like to know what would you guys recommend as a replacement for 4500 and 4006 units?
There are still some clients on the network with static IP config. I'd like to eliminate this as well as the need for router on the stick for VLAN routing. I was thinkin about running 2 fibre links for each access switch (1 for each core switch) and configuring VLANS with DHCP. Is there a way to achive redundancy, so if one core goes down the other will take over? I'm trying to find some config examples to achive this and eliminate router on the stick. I know that I could use 4500 core for to perform layer 3 switching. Could someone help me with config examples please?
Does above sounds like a good plan and direction to go to achive scalable and 1Gb backbone down the road?
Firstly, I want to know if your finances will allow you to move up to 6500E. Next question will be your timeline.
Let me let you "in" in a secret. In the next 18 months, a new 6500E supervisor engine, called the Sup2T, will come out. If you are interested in this, DO NOT get the 6708-10GB blade.
(4506 end of life perhaps?)
4500, like the 6500, has around 5-10 years worth of "life".
18 x 10Gb fiber ports to accommodate access switches
Hmmm ... you have a choice of the Sup7E for the 4500E and the new Sup2T. Personally, if I can stall the project, I'd go to the Sup2T. If management comes down and ask you why you don't want to purchase NOW, tell them it makes common sense to wait for the new product to arrive rather than buy a product which will be superseded with something else.
All Supervisor Engines for the 4500 and 6500 will support PoE. All you need is to get the right 10/100/1000BaseTx blade. Also for the non-PoE 10/100/1000BaseTx blade, what are you going to use it for? For servers connected to the 6500 the 6748 is recommended.
1 x 48 Gb module with PoE
3 x 48 Gb modules
By the way, there's one additional feature that I've forgotten to mention:
The new switches that were un-veiled recently were the 3560X, 3750X and the 2960S. Each has it's own "thing". But what caught my interest is the USB port.
We've already played with the 3750X and the 2960S. I can upgrade IOS, copy file(s) to and from the USB stick all by using the USB port.
But we confirmed another feature: Boot IOS from the USB stick.
Another thing we did was format the switch flash and let the switch boot into ROMmon. Next (still in ROMmon), we instructed the switch to boot the IOS that was stored in the USB stick. It works!
So, if you have these models and suddenly one of your switch dies because of corrupt IOS, you know what to do!
If you are interested in this feature, make sure your USB stick don't go more than 8Gb (I have tested up to 2Gb but couldn't go beyond that because we don't have any 8Gb USB stick available, maybe someone can test the 8Gb and let us know). Also, format the USB stick using the switches.
Hope this helps. Please don't forget to rate our useful posts.
