On WLC > Wireless > AP > High Availability, do the controllers have to be on the same LAN? In other words, can they be located across a layer 3 boundary, say in different geographic location?  I don't see how Secondary WLC can support an AP that not configured 'locally' (local interfaces, WLAN, AP group, etc.).  H-REAP presumably.  I configured many of those and they work great (local switching).  My understanding is that an LAP *must* be local with an interface, WLAN, AP group, and a local Vlan trunked to the WLC interface.  Can somebody clarify this for me? Thanks. ... View more

Question about an optional solution for H-REAP (FlexConnect) CAPWAPs.  I have many H-REAPs in small corporate offices with local switching and they work fine. However, I believe in some cases there may be a better solution for me and the TAC can't seem to understand my query for help (or perhaps I'm a miserable communicator!!). For simplicity sake, assume I have a CAPWAP located within my campus but in a different switching domain that my WLC.  In other words, it is located across a routing domain and thus VLANs and their tags are confined to their own domains.  Rather than using FlexConnect I placed my "remote" AP in a Vlan local to the remote domain and assigned it a static address.  I statically configured the AP to register with the WLC.  All is fine so far.  The AP registered and showed up by default on the WLC management interface. I want to move the AP to its own dynamic interface and WLAN and enable the WLC to support DHCP to clients to obtain IP addys following WPA2 RADIUS-based authentication. Here's the question/problem:  dynamic interfaces *require* Vlan assignments with IP addy/mask/GW.  This seems to be an illogical and useless step.  Moreover, the TAC indicated that the VLAN should be added to WLC port trunk!! That seems even more illogical.  I can understand a "vlan" in the CAPWAP tunnel (WLC<=>AP(remote)) "understood" by the WLC and CAPWAP but on the WLC trunk where this Vlan tag has no meaning in the WLCs switching domain!?  So is there really a topology and configuration that supports "remote" CAPWAPs other than FlexConnect?  And if there is, does the WLAN or dynamic interface pointing to the DHCP server provide the CAPWAP with the mechanism for client IP leases?

Got two new boxes that I am thoroughly impressed with. What am I missing? I want to reset Ethernet interfaces to default status as in IOS: (config)# default interface f0/1 <cr>. I've search command reference syntax high and low. I've learned more of the CLI trying to find something that would return an interface configuration to its default. Which is good but... I do not trust issuing a set of 'no' prefixes to configuration lines. That is not smart in IOS and I suspect not in NX-OS also. Help. Thanks. ... View more
