RE: DHCP issues with V73
Hard work to find out the error! Disabled the "Smartport"-Feature in Cisco-Switch, disable lldp on Phone and now it runs!

I dont know what the problem is... in old firmware there was no problem!

If i set phone to vlan200 and manual ip, i reach the phone.
If i disable vlan configuration and set IP in our pc net (which is normaly no problem because untagged vlan10) i can't reach the phone.

The Cisco switch smartport-feature set additional port-settings, but if i manual set this options... no problem.

interface fastethernetXX
port security max 10
port security mode max-addresses
port security discard trap 60
macro description ip_phone_desktop

Only setting i not tested was " spanning-tree portfast".

Why is lldp standard enabled? Should be disabled!
