Apologies for the noise. Please hit delete... Once again I am not able to send email to the list and have either been moderated off again (for some mistake or some unknown reason why) or something else is going on. Sent email to admins@, but no response, so this is just a test to see if anything gets through. scott

3rd party QSFP-100G-LR4-S for Cisco
by Ryugo Kikuchi 10 Jun '18

10 Jun '18

Hey all, Does anyone have a recommended model of 3rd party's "QSFP-100G-LR4-S" for Cisco ASR and Nexus? Cisco's original 100G SFP costs us an arm and a leg, so we want to try to use 3rd party 100g SFP. But we are not sure which manufacturer's SFP is reliable or has good performance. Does anyone have experience? Many thanks, Roy

AT&T Res Fiber Chicago contact?
by Brandon Ewing 10 Jun '18

10 Jun '18

Howdy, I've been struggling for a few weeks trying to identify whom to speak to at AT&T regarding pre-wiring of fiber in our small (6 unit) HOA. I know the fiber is on the pole (it lists our address as in the service area), but I cannot get the service installed without impinging on other units. I'd like to work through the HOA to set up a new easement alongside the existing phone and cable currently running through all the units, but have not had any success with the multi-family unit form at AT&T (I think it's designed for large apartment buildings), or through the customer support apparatus. Seeing as how my current choices are bonded aDSL and Comcast, adding a 3rd party would be extremely advantageous to the HOA and provide turnkey access to the rest of the residents. If someone knows someone at AT&T who could assist, I would be extremely appreciative. -- Brandon Ewing (nicotine(a)warningg.com)

Application or Software to detect or Block unmanaged swicthes
by segs 08 Jun '18

08 Jun '18

Hello All, Please I have a very interesting scenario that I am on the lookout for a solution for, We have instances where the network team of my company bypass controls and processes when adding new switches to the network. The right parameters that are required to be configured on the switches inorder for the NAC solution deployed to have full visibility into end points that connects to such switches are not usually configured. This poses a problem for the security team as they dont have visibility into such devices that connect to such switches on the NAC solution, the network guys usually connect the new switches to the trunk port and they have access to all VLANs. Is there a solution that can detect new or unmanaged switches on the network, and block such devices or if there is a solution that block users that connect to unmanaged switches on the network even if those users have domain PCs. Anticipating your speedy response. Thank You!

Carrier Ethernet Interoperability between Juniper and Ciena
by Gary A Mumphrey 08 Jun '18

Hi All, Anyone out there creating carrier Ethernet services terminating services on one end with Juniper and the other end with Ciena? The particular Juniper platforms we are looking at are the ACX5000 series and/or MX204. We already deliver an end-to-end Ciena solution for our customers with their CES (3000/5000) platform. Thanks.
