We are about to redo our stand alone wireless with WLC's and LWAPP's. As part of the process we are implementing ISE and were going to implement the Wireless Control Station, but it has morphed into a wired/wireless all encompassing solution called C...
The module is shown to be rated at 400G. The 2x100 in the part number would lead you to believe it is only rated for 200G. Is this truly a 400G Transceiver? With an MPO24 Interface how does it achieve 400G over 10 TX Lanes?
Hello. I have been having issues with this one interface GI2/0/4 on L3 Cisco 3850 switch that's been throwing out lots of Rx power low alarm; Operating value -26.7 dBm; Threshold value: -21.0 dbm logs. My senior tech and myself have already troublesh...
Dear community. I am stuck up on the SFP issue. I have Cisco SFP-H10GB-CU3M.When I am trying to connect something to a 10g port with these SFP, it is not working at all. But when I connect other devices with these SFPs everything works fine. I can se...
Does this point to an issue with an SFP? We have a 4500-x vss stack, through which runs the heartbeat for a bunch of vrrp groups upstream, both routers have been going active due to loss of heartbeat. One of the switch uplinks has a tx power of -10db...
I connected a 40GBASE-CR4 Passive Copper Cable, 1m cable between 2 x C9500-24Y4C-E switches, but I don't get a connection. Is there something I am missing?

Good evening folks, question for you:Am I crazy, or does Cisco not have a 10G LC mm SFP that that can also be adjusted to handle 1Gb/100Mb/etc. ?We have a large project at work that is fully 10G LC fiber; however, we want the capability to connect to...

What is the added intelligence in routed optics? Does it repair the network's data transmission capabilities (originally at layer 2) by itself? Is there a missing layer 2?I am struggling to understand the "routed" aspect of optics. If you could pleas...
