Has anyone configured an OC3 interface for a connection to an alcatel microwave/radio link. We have a private 155mbps microwave service running over alcatel equipment and we are using a 3620 with an OC3 interface at each end to connect to the alcatel equipment. It looks to be configured for ATM on the OC3 interface but the providers of the alcatel equipment have said it is not ATM but STM-1. The link is working to some extent but we have a lot of performance problems. Does anyone have any experience in a setup linke this or can anyone advise of some references to check.
If you see AAL5 length voilations, it means that cells are being dropped causing packets to be corrupted and thus dropped. When you issue a show controller atm x/y, do you see any errors ? It is possible that the satellite link or the Alcatel boxes are causing a problem.
One test you could do is a loopback test. Physically loop the router ATM interfaces and have each of them ping their own ATM (sub)interface. If you are dropping packets in that scenario, it may mean that you have a hardware problem on that router. If that test runs clean, then the problem comes from the satellite link or Alcatel modem.
One thing I forgot to mention. If you have configured the main interface or a multipoint sub-interface, for the router to be able to ping itself, you will have to add a static mapping for the router IP address under the PVC. If you are using point-to-point sub-interfaces, there are no changes to make.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
