We are planning to upgrade our network and comparing different models of switches and router. At this point we have about 300 nodes and 400+ users on the network spanning 4 buildings, but in the near future it is going to be expanded to around 700-800 nodes. The following are the devices we are looking at:
Internet edge routers - 2911 router (already present) + 2951 K9 (to purchase)
Core switches - Two L3 switches - 3750 X Lan base, Stacked
Access switches - couple of L2 switches - 2960 Stacked
Please kindly give us any advice if the selection is good enough to handle 700+ user and 700-800 network devices.
Thank you very much!
As per the user count the above devices looks ok.
I would suggest you to have two routers in HSRP mode as edge internet routers.
The 2951 for edge internet routers is ok, but again if you have large amount of encryption needs to be hanle by edge routers then you may need to look at higher end routers. If it is plain internet facing traffic then it is ok you are fine.
When you say 800 users will it increase in future? if that count will increase you may need to look at higher end switches like 4507 or 4506.
2960's as Access switches are perfect, please consider PoE ports you may have IP phones (these may already existing or may come in future)

This choice mainly depends on the type of traffic that traverse your network and how busy it is
Such as VoIP, video, web, citric ".etc
Generally speaking in agree with the above proster interns upgrading the core switches/ and I think your network run collapsed core and aggregation layer within same L3 switches
In this case the 4500 switches good option for future growth and better performance with dual sup for intra chassi redundancy
About the Internet routers it depends how much bandwidth you have and if you are going to use any sort of encryption such as IPSec VPN
Hope this help
If helpful rate
Thank you so much for your advice everyone, Latchum Naidu, Marwanshavi! Really appreciate it.
Latchum Naidu, the 800 user count is probably going to be the maximum within the next 5 years.
Leolaohoo, we have no WAN connection. All buildings are located in a single campus and are connected by fiber optic cable. Routers will handle only internet facing traffic. Current bandwidth is 50Mbit, but in the near future will be upgraded to 1 Gbit.

IF 1Gb is what you're aiming for then consider an ASR1002 with RP1 as a minimum.
Core Switch - 3750X with IP Base, redundant PS or 4500R+E with Sup7E or 6500E with Sup2T (same price as Sup720)
Access Switch - If you are stacking more than 4 switches, then 3750X with LAN Base IOS. If you are stacking up to 4 switches then 2960S with LAN Base. 10 Gb options for both 2960S and 3750X are available.
If the user count is 800 then go a head with 2911 will do the job perfect for you.
And for your core switch you can go either stack of 3750 or 4507r+e, its all up to your budjet and your management willing.
And for access switches go with 2960's with LAN base IOS image, these switches have 4 10G ports (if i am correct) these ports you can use for uplink between your 2960's.

Routers models alwyas measured by bandwidth rather than number of users interns of fasswitching and packet forwarding per second pps
Example if you have 1000 user and 1M WAN link then you need to consider the 1M when you design your wan even though you have 1000 user
Switching wise, I would go with the 4500 series in your core, preferably the 4507 for redundancy. The 3750 would be perfect if you weren't planning on growing double your size in a short amount of time. It would be a shame to purchase the 3750s now and have to purchase a 4500 six months to a year later to handle more features that you didn't think you needed in the beginning.
