LRE Bandwidth Question

Hi,

If Catalyst 2924-LRE switch connected to 24 CPE575 devices connecting Access Points to each CPE, What maximum bandwidth will be available to each Access Point while they are communicating at the same time.

Is 15mbps is shared among all 24 LRE ports or each CPE (LRE PORT) has dedicated 15Mbps available if this solution to be built operating all Access Points at the same time.

Please someone help me as soon as possible.

Thanks

Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer.

Re: LRE Bandwidth Question

I confirm the 15 Mbits (maximum on a short distance without noise and other problem).

quoted "12 or 24 LRE ports, each delivering dedicated per-port symmetric bandwidth up to 5 Mbps (up to 5,000 feet), 10 Mbps (up to 4,000

feet) or 15 Mbps (up to 3,500 feet) over Category 1, 2, or 3 single-pair copper wiring to support advanced network services." from

Good luck

Re: LRE Bandwidth Question

Don't forget if you're going to be using all ports you probably want to run EtherChannel to the switch over the 10/100 ports.

I have found the LL profiles to give MUCH better thoughput on the LRE side.
