I am replacing three 2948 switches with a single 4506 with 4 modules of 48 gb ports in my server farm. The Sup has two 10 GB ports but the core switch doesn't.
Is there something I should be concerned with as far as my uplink to the core switch is concerned considering that I will be going from using 3 fiber connections(to my three old switches) to using just 1(on the 4506)? Note that all the 3 old switches are fully loaded with servers.

Also, I am having problems upgrading my IOS with the errors below. Only tried once but decided to add the question here to have everything taken care of since I don't have too much time for research before deploying this switch:-

Since you are collapsing your 2948's into one 4506 you are introducing a single point of failure.
Are you utilizing dual sups? This decreases your failure domain.
Soounds like you have only one core switch, I would do the following;

create a etherchannel (multiple gig ports combined into one logical pipe), that way in case of a single port failure the remaining port/link will be active creating some redundancy in the link, make sure you diverisfy your connections onto seperate line cards if possible, again this increases your availability.

As far as your tftp problem it could be several things;

do you have IP connectivity to the tftp server?
Is tftp server running on the box
Is the file in the tftp root directory
Are the permissions on the file and directory correct?

I didn't mention it in my earlier post but my concern is about throughput between the 4506 and the 6509(which is on HSRP  with another one).
Yes, I only have one Sup and I am considering recommending another one if possible.
Please check my attached topology and let me know what recommendations you may have for me.
Would like to avoid etherchannel if I can. The 4506 only has two 10 GB fiber ports anyway and must be connected to both 6509s.

On my TFTP issues, I am able to copy the switch configuration back and forth with no problems - just the image copy to bootflash that is giving me that error.

So is the connection between the 4500 and the 6500s a layer 2 or a layer 3 connection?

Why aren't the 6500's connected?

Sorry, I mised the interconnection between the 6509.
Only Layer 2 between the 4506 and the 6509s.

For the sake of completion, I have fixed the error in my diagram....and even added some other connections to routers.

If you need to use the 10Gig then you should connect each to a unique 6500. I assume you have the
Supervisor Engine II-Plus-10GE ? Only problem is that you have a single point of failure with the linecard, you can run diverse connections but if the linecard fails you are done. However, I understand budgetary contraints. I would try to load balance the vlans over both trunks utilizing HSRP groups on both alternating primary and secondary.

Let me try to explain a little further what my exact question is:
The New 4506 has One Supervisor Engine-6E with Two 10 Gigs { I understand I would need to do one each per 6509}
The 4506 has 4 WS-4548-GB-RJ45v Plates which will carry all my servers.

The 6509 has a Supervisor 720-3B with NO 10 GB ports and that is the crux of my concern. Getting the 4506 running without sacrificing uplink bandwith to the 6509s


It occurred to me that the 4506-6e is designed to carry only one Sup engine at a time so I don't mind buying a spare and leaving it unconnected - The network can be down for the time it takes me to prep another engine and get it running.

There are zero budgetary constraints for my needs.
Now let me hear  your recommendations.

The real question is, what are your requirements? most orgs donot/cannot use 10G. Depends what you are trying to do. You have alot of horse power there, you certainly can do alot if needed.

Use etherchannel if you need the badwidth, you can get up to 8Gigs in a bundle without using your 10G ports. The other question of course is, how much traffic is actually traversing the 4500 towards the 6500. If it's not too much then 1G ports to each 6500 will suffice. Depends on your traffic chacrteristics.

I think you answered my questions. I have re-examined my switch. Have no idea what was going over me but it does have 6 fiber ports with leave me to bond two each per 6500 as you suggested.
My worry now goes back to the 1 sup which I will just have to order and keep for the rainy day.
By the way, got the IOS pushed to the flash.
Any idea what the Tel/1 and Tel/2 ports are?
Thanks again. I should be able to close this question when I get home.

By the way, you notice my G13-6 showing as inactive??? I have G3 and G5 connected to a known functional catalyst 3750 in a test environment. Again it is a long day so I will probably figure that out by tomorrow.

Te1/1 and Te1/2 are the Ten Gig ports.

As for the SUP, I would definitely add to the chassis and let go to standby mode, in case of a failure you can get things going very rapidly.

The "sh  mod" show that there is no GBIC in those ports  ;}

sometimes you jsut need another pair of eyes, good luck

I think your input has been very useful.
Review my attachmet from the configuration guide for this switch.
The Te1/2 and Te1/2 are the Ten Gig ports as you rightly said. The naming convention is however very confusive.
There are two X2 holes which can either support 10gb each, or two gigabits per X2, or all 10gb and 4 gigabit ports! Since there are two X2 ports, the gigabits(SFPs) starts from 3 to 6!  Only the 10 gb is enable by default hence showing as notconnect while the disabled gigabits are showing as inactive.
Later, when I get to office, I will post configurations with the gigabits active...hopefully.
