WLC across WAN

[tejovadhry]

Hi all,

Setup overview

Wireless setup accross different branches (WAN) with WLC at head office.

> configured h-reap mode AP's for remote branches, and local mode AP's for devices under same LAN as the WLC.

> Different subnets for different branches defined and vlan identifier assigned.

> virtual interfaces created in wlc for all respective  branch vlans.

Observation: For all the additional virual interfaces created for the vlans we see same mac address (same mac address seen for diff vlan interface configured) and  found mac flaps for against this mac in the lan where wlc is placed.(flap was intermediate and did not cause outage though)

Questions:

1. Is it okay to connect the management port only to the network and let the entire communication go through it?

2. is it necessay to have a vlan identifier assigned in wlc(locally) even for the remote branch subnets?

Thanks in advance

Tejo

The WLC should only have interfaces that is local to that network. No interfaces are required or should be created for remote sites. The vlan mapping for remote sites are done from the h-reap ap. as long as your clients are not switching between different SSIDs on different vlan's, you shouldn't see MAC address flap between two different vlans. I have seen MAC address flap also with no impact to the network.

I would segment as much as you can since its best to do so if you can. Can everything use the management, sure, but do you really want to do that.
