Avaya has released v22.214.171.124 software for the Ethernet Routing Switch 8300. This software release is significant in that it finally adds LLDP-MED functionality and support to the 8300 switch for IP telephony deployments.
The purpose of this feature is to allow an IP Phones to get voice VLAN, DSCP and priority,tagged/untagged traffic type’s information through LLDP MED Network Policy TLV. LLDP-MED functionality is configured on a per port basis.
When an IP Phone sends a LLDP PDU with MED capabilities the switch will notice that it has a MED endpoint device on that port and will reply with a PDU containing the Network Policies TLVS together with the other non-LLDP-MED TLVs already set for transmission.
The LLDP–MED standard specifies that if the MED capability TLV is not received from an endpoint device on a port than no other MED TLVs except med-capabilities will be sent to the user in a PDU.
The VLAN information is sent to the IP Phone through LLDP-Med Network Policy TLV. Multiple Network Policy TLVs can be sent in one LLDP PDU, each for a distinct application type.
Please review the release notes for any additional information.
