Network Infrastructure Upgrade

TECHNO.IT used Ask the Experts™
Hello Experts,

We are planning for a network infrastructure upgrade. It includes structured cabling and active systems.
The network is currently running Cat5e cables, patch panels and faceplate modules.
Cisco Catalyst 3560 is deployed at edge and 6506 at Core.
We want to upgrade the infrastructure to Cat6a structured cabling, Fiber cabling supporting 10g and Cisco Switches with  SD-Access.
Therefore, we are looking for tips and suggestions to start preparing the plan.

Downside to the above - twice the expense for no real throughput gain.  Unless you are hanging a NAS or monitoring server of a phone, there just isn't enough utilization by an endpoint to justify not running both your VOIP and station traffic on the same drop.

Agree with modular jacks and patch panel.  Industry standard.  If your lvCu guy tries to put anything else in, he doesn't know what he's doing.

Report on runs - should include jack to PP map, length of run, run validation test of each patch.  Before you pay him, go through and verify by random sample: the map (tone testing, wall plate to PP) and validation tests.

Cisco SDA - do you run a NAC solution today?  If not, is it a requirement?  SDA sounds really cool, and it is, but that coolness comes at an administrative cost.  If you are going to run SDA, you will need to start getting your head wrapped around LISP and VXLAN.  You will also be looking at an increased deployment of ISE.  Long and short, if you don't have a compelling requirement beyond it makes you warm and fuzzy, don't go down that path.

Also, you need to recognize that if you blend in new connectivity technologies like SDA, you are going to get into serious considerations of the when and how.  There is a lot of heavy lifting that is going to need to be accomplished to transition your environment into the new tech which is going to translate into off hours labor for you and your team (if you don't have one, you are going to want one).

Personally, based on what you have noted above, I would look at the Nexus 9K platform at your core/distribution and then go with the Catalyst line at your edge (the 9Ks that you are most likely looking at for your SDA deployment will still work as traditional access.

On the 10G - if you are using it to uplink your core to each other or servers to your switches, then go I prefer using the DAC cables.  Everything is fused end to end and warrantied as one piece.  It also takes a third party blame point out of the equation in the event you start having layer 1 problems if you buy from Cisco.  From your access switches to your core, if you are going to shoot 10G, just go with traditional fiber.


@ atlas_shuddered: Thanks for the detailed and informative reply.
We don’t have NAC at the moment but planning to have one.
The purpose of having of SDA is to prevent:
- Bridging loops and STP issues
- Scalability.
- WLC integration
- Configuration Automation

We intending to have Catalyst 9300 on edge and Catalyst 9500 as core and we are going to have parallel run between old and new network.
But got an issue with one IDF room where room space is congested and new rack cabinet cannot be placed and we are not allowed to a new room due to space management.
So is there any other alternative solution to this kind of issue ?


Any further suggestion please ?
