RE: T42G dhcp issue
Hi,

Please apply some info below for us, so we can check more.
1. The firmware version of your phone?
2. How many phones in your side, all Yealink phones can't get voice VLAN?
3. Do you enable CDP? Maybe you can disable then test again.
4. Please help us to get the PCAP and syslog and config.bin file.
Please disable VLAN option, then access web interface->set system log level to 6.
Then enable LLDP->reboot phone->if the phone can't get IP address, please set static IP then access web interface and export the system log and config.bin file.
5. If you have a HUB in your side, please also help us capture the PCAP file.
