Description (partial)


A 2100 series WLC may stop responding on its LAN ports.


A duplex mismatch is configured - for example, the WLC port may
be configured for half duplex, but the connecting port (the port
on the device to which the WLC is connected) is configured for
full duplex.  This hang is then seen under load.
