Hi,   Our WLC is configure in LAG mode, this means I can only configure one AP manager. The problem is, I have over 255 APs so the only way I can deal with this is if I use a /23 on the interface that the AP manager is configured on.   Please can you let me know if there is a recommend configuration other than creating a /23 subnet? ...

Hi all,   We are in the process of planning for a new development in a city center. As you can imagine, space is at a premium. When I have designed networks for new developments in the past, I've always specified one cab per floor for various reasons such as, cable length and future expansion, not to mention the issues that come with running cables vertically between floors.   I believe I'm going to experience push back from the project team for the little amount of space my network design requires so, I was wondering if you guys do this same, i.e. a comms room on each floor of a building? If so, what are your reasons for doing so, if not, what did you do instead?   Kind regards,   Jamie. ... View more

Hi all, Pretty simple question. I have several WLC's in HA mode and they work great. The problem I have is that they have to be directly connected via the redundancy port which makes it difficult to place them in a different building. So, the question is, is it possible to have two 5508 WLCs in HA mode without using the redundancy ports? I have tried this and it doesn't seem to work. I was wondering if anyone else has had any success with this? J. ... View more

Hi, I will try my best to describe our issue. We have two sites, A and B. We have recently created a backup data center for our virtual servers using vRanger and NetVault on site B. In a disaster scenario such as, we lost our primary Site A, we would like the ability to turn on the backed up servers that reside in Site B and have them just work. The problem with this scenario is when the servers turn on they will have the default gateway of the router in Site A and thus won't work. Yes, we can go in and manually change it but it's a step that we would like to negate. The options that I have come up with is using VRRP and point the servers to a virtual IP. Or we could define the VLAN that the servers use on Site A on Site B but shut the VLAN down and only bring it up when needed. I hope this make sense. Please, if you need any further information to help me with this, just ask. Kind regards, Jamie. ... View more

Hi, On a few occasions we have experienced issues with a stack switch where it has failed. The problem is Cisco Prime 2.2 does not notify us because the stack IP address it still contactable. The stack does produce a syslog but it is only an informational notification. Does anyone know of a way we can programme Prime to alert us when we lose a stack switch? Jamie. ... View more
