Hi all
I got an error message "Bad tftp1 address" when connecting an Alcatel IP Phone to Cisco 2960CX switches.
In our network, we have several switches with different models. And when I moved the IP Phone to other switches rather than 2960X, it works fine.
I have checked the configuration of Voice and Data Vlans several times, they are configured properly on 2960CX switches like on other ones: trunked to core switches. when running "show spanning-tree vlan Voice_VLAN", it shows that core switches are root bridges for the Voice VLAN. "switchport access vlan Data_Vlan", "switchport voice vlan Voice_Vlan"...but it could not help.
Thanks!
