RE: DHCP issue on Yealink phones with HP Switch HP2920

Hello Crizz,

Can you please upgrade T42G to V80 and do the follow test:
T42G V80 firmware: ftp://James:494qh65Z@ftp.yealink.com/fir...0.0.60.rom

1. Login into phone web interface, enable "Span to Pc" under Network advanced. Set the syslog level to 6 under Setting-> Configuration.
2. Connect PC to phone PC port and start wireshark, reboot phone. After phone get an ip address, export the pcap trace and syslog.
3. Re-start wireshark in PC. Enable/disable LLDP, phone will reboot. After phone get an ip address, export the pcap trace and syslog.

We can check what phone receive and react to packet from switch.

Thanks
James
