can any body tried to aggregate the Four SFP ports on Cisco Catalyst 3560G-24PS-S switch,
which it it is required to connect end users to it via 10/100/1000Base-T ports then make the uplink connected to Cisco 4510R-E Core Switch via 2uplinking(One Fiber and Other UTP to provide 2x1000Base-T uplink)
the same configuration will be on Core Switch 4510R-E switch which we need to aggregate two ports one fiber and one UTP on different modules to provide also 2x1000Base-T ports on the Core Switch.
please advice with your experience.
i can send the design for more details about my network
This can certainly be done, even though I wouldn't think that using fiber, and UTP would be the best idea for a port channel. Is there a reason why you would want to use fiber and copper? Here is a guide for configuring etherchannels.
I understand what you trying to do. I was just asking to get an understanding on why you wanted to use copper and fiber. I'm sure this will work, just remember that both links must be configured the same, and be the same speed.
Yes - I had the same request to do this once for redundancy purposes. So that if somebody cut through the building VCC Fibres it the UTP would instantly take over the traffic.
Unfortunately this cannot be done even though in theory it would appear it could. The only reason I beleive that you cannot use etherchannel or LACP with two types of media is that you will have ever so slightly different propogation delay's due to higher electrical resistance over copper media compared to the photon's over fibre. However this is only my guess on why it is not allowed. I would be intrested to know of anyone else's opinion?
This type of port aggregation is not permitted with Nortels version of Etherchannel which is MLT and SMLT (Multi Link Trunking)so it is not just a cisco restriction.
I have found some documentation that suggests that it may well be possible to run a mixed media port channel of both copper and fibre on 6500 running IOS and not CatOS only. Can't find anything on other models about mixed media though.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
