Maximum Power Setting on UPoE Ports

The Maximum power that can be provided by an UPoE power of AS4610-54P is 51 watts instead of  64 watts. So the range of max-power of a specific port is changed to [1..51].

Phone classified as CDP If LLDP Enabled Capabilities are not Set Correctly

Verizon has phones which do not set LLDP Enabled Capabilities:Telephone correctly (Not Enabled), but the LLDPDU includes Network Policy TLV requesting policy for Voice application. PICOS LLDP/CDP would classify these phones as CDP phones and send untagged voice related traffic to these phones, which is not expected by the phones because of the LLDP-MED negotiation. PICOS should classify the device as a LLDP-MED phone, if the switch receives LLDPDUs from the phone with LLDP-MED Network Policy TLVs for Voice, EVEN IF the base LLDP has “Enabled Capabilities::Telephone=NO”. The logic is that if the device is requesting LLDP-MED Network Policy for Voice, then it must be a phone, and this overrides the fact that Enabled-Capability::Telephone=NO.

PoE Power Provision Error If the Phone Has Different Chassis IDs with Different IP Addresses

The attached phone sends LLDPDUs with 2 different Chassis IDs which are the values of the IP addresses. Initially, the Chassis ID/IP address is 0.0.0.0 and then becomes such as 104..255.99.11 when the phone gets an actual IP address from the DHCP sever. The initial LLDPDU with 0.0.0.0 requests 12.1 watt. And the following LLDPDU with 104..255.99.11 requests 15.1 watt. Unfortunately, the LLDPDU with 104..255.99.11 is ignored. PicOS switch should continuously check the the TLV of Power Via MDI and provide the power requested by the TLV from the incoming LLDPDU.

Port is not Deleted when Change the User Status

A port is secured by 802.1X and configured with a dynamic VLAN such as VLAN 8. And then the dynamic VLAN is changed to VLAN 9 on the side of RADIUS server such as PacketFence. The re-authentication doesn't change the dynamic VLAN of the port to VLAN 9 on the side of Pica8 switch.
