Wireless Clientview, error?

Robert Tausend
Hi,

i just added a few WLan clients to my network, on some i see the "network" name, on some i didn't see them, is that a bug? In my opinion this should be available by the DHCP Lease?

Regards
Robert

    When a client device successfully connects to the wireless service, the ASG checks if there is a lease for that client (MAC address) present. If yes, we use the IP address for that lease, and the hostname which was submitted by the client during the DHCP request. If there was no hostname submitted, the DHCP server usually provides "[unknown]" as hostname.
    If there is no lease on the ASG (which happens if you either use a different DHCP server, or use a static mapping) the IP is set to 0.0.0.0 and the hostname is set to the confd REF string.
    Currently there is an issue with the leases: in some cases, the DHCP server has multiple lease entries for the same MAC address. In those cases, if one of those entries has the "[unknown]" host name, it can override a lease having a correct hostname. Workaround is to set the name manually in Wireless Clients, this always overrides data from the DHCP server.

    There is another issue when creating a static mapping after you already have obtained a dynamic lease: since the static mapping can not be found on the ASG, but the dynamic mapping still exists (the DHCP server does not seem to purge them immediately), the wrong IP will be shown. So for static mappings, you currently have to always set the name manually.

    Fixes for those things are already committed, but as this was done already two weeks ago I temporarily forgot that they are not fixed in the 7.506 release. [;)]
