I have a foreign controller that will not pass traffic to the anchor. I reckon it must be a config issue but I cannot find the problem.
The mobility paths are up between the two controllers and I've checked the LAN config and everything seems to be ok.
I have debug output (attached) from the foreign controller showing obvious DHCP issues (as the anchor doesn't seem to get any traffic passed to it from the foreign WLC) but I was hoping someone would be able to glean further clues from it.
Without providing following information, it's hard to say what's wrong:
1. Anchor and Foreigh WLC model/version/configuration
2. mping&eping result between anchor and foreign WLC
3. show mobility anchor in both anchor and foreign WLC
If each time it stuck in DHCP, most times it is because of mismatched WLAN profile configuration(especially DHCP configuration in Advanced Tab, such as one WLC configured with DHCP required, while another not configured) or the anchor WLC has not configured itself as mobility anchor, different SW version, etc.
