RE: DHCP issue on Yealink phones with HP Switch HP2920
Hi guys,

As per first above configuration I did some package capture with Wireshark on mirrored port of one of the phones ports connected to and I noticed that the DHCP server is issuing IP’s on VLAN 50 but for some reason the phone doesn’t receive or can’t accept the offer of new IP, OR the Switch is blocking those packages. DHCP is not doing any entry on the released IP list but is trying to release a valid IP. Is probably waiting for phone to accept it first. This is what I understood from the wireshark capture. I don’t know if its from the SW area or from the phone.
I just remind that this issue it happens only for the yealink phones, all other devices are getting DHCP on the VLAN 50. And also the phones are getting DHCP on VLAN 1 (the DHCP is on this vlan).
In production, the main SW is and HP POE v1910 layer 3 and this is working with same configuration. And the yealink phones are getting DHCP.
Shall I open a ticket on Yealink or with HP? This issue is very frustrated, I couldn’t find anything anywhere!

Other ideas?
Thanks in advance!
