[c-nsp] 500 msec timers on Cisco GLC-T

[Mike Louis]

Hey Folks,

One of my Cisco SEs told me the other day that there was a limitation in the GLC-T GBICs that prevented the switch from recognizing a  link up/down faster than 500 msec. This could cause a noticeable blip in a voice call. Apparently this is not an issue in the fiber SFPs. Has anyone ever heard of this  before. He was referencing a 3750 series switch when we were discussing the issue. I am not sure if its platform or GBIC specific. I also wonder if it affects normal 10/100/1000 ports the same way. Any ideas or thoughts? Ever heard of anything like this on other platforms?

Thanks

Mike
