Yes all the radio RF levels are 100% ok. -----Original Message----- From: Josh Cheney [mailto:josh.cheney () gmail com] Sent: jeudi 10 septembre 2009 12:47 To: Rens Cc: 'Adam Goodman'; nanog () nanog org Subject: Re: Wireless STM-1 link I'm assuming that you have checked all of the wireless parameters (noise floor, signal strength, jitter, etc)? I've seen behavior like this on links where the noise floor has risen to the point where the true signal cannot be distinguished from background noise. Josh Rens wrote:
All the interfaces are forced to 1Gbps and full duplex. Maybe I should give some extra info. All the traffic seems to pass ok via that link but I have seen that often OSPF adjacencies go down/up , I suspect that the HELLO packets are being dropped that pass via that link. That's why I started to look a little deeper and do some ping tests. -----Original Message----- From: Adam Goodman [mailto:adam () wispring com] Sent: jeudi 10 septembre 2009 11:45 To: Rens Cc: <nanog () nanog org> Subject: Re: Wireless STM-1 link Sounds like this might be an Ethernet negotiaton problem -------- Sent from my phone On Sep 10, 2009, at 12:05 PM, "Rens" <rens () autempspourmoi be> wrote:Hi all, I'm encountering a problem with a wireless STM-1 link which has a switch connected at each end. The wireless link has Gigabit Ethernet interfaces and so have my switches. When I ping between the 2 switches via that wireless link I'm getting a lot of pings that are lost. The wireless link is not saturated but I'm thinking it could have to do something with the gigabit interfaces and only having 155Mbps on the link itself? All ideas welcome. Regards, Rens
