Hi,
We have a problem after a firmwareupgrade on our 7911 Phones.
The old firmware was SCCP11.8-0-4SR2S
The new firmware is SCCP11.8-3-5S
We have the Phone attached to the switch and the PC is connected to the phone.
The switchport configuration looks like this:
interface FastEthernet4/48
description Access-Port with IP Phone
switchport access vlan xyz
switchport mode access
switchport voice vlan abc
qos trust device cisco-phone
qos trust dscp
no snmp trap link-status
tx-queue 3
priority high
spanning-tree portfast
spanning-tree bpdufilter enable
At the beginning the Phone runs ok, after an indefinite time the phone have two ip addresses, one in the voice vlan and one in the data vlan.
After that, the phone boots and can`t get its configuration from the TFTP server.
Is anybody know this problem it is a really strange thing
Thanks
Martin
