Hello-
Budding wireless engineer here. Was hoping to run this issue by the message board to see if anyone has the same issue. About 98% of our campus buildings are fed with fiber, but the remaining 2% are legacy HDSL circuits. We are in the process of swapping out MSM gear with Aruba 6000's and AP-135's(yea!). My questions are regarding HDSL and RAP.
Now, to add a little history. We were never able to successfully configure an MSM460 over an HDSL circuit because of an issue of MTU packet size; HP could never fix it and the AP would never negotiate the link. So, as a fix, we had to keep RP210's around to give the HDSL sites wireless access. When we tested the AP-135's on HDSL, we configured them as a RAP and they worked! It was sort of a deal breaker........ :)
Now, is there someone who can explain to me what is happening? How can the AP negotiate this link? If the AP is used heavily, won't it clog the link so much as to create network latency to the other vlans piped to the building?
