My issue is that the LLDP frames sent for DCBX do not contain a system name. When the switch (EOS 4.27.4) receives the DCBX LLDP frame it forgets the neighbor system name, until the server LLDP frame is received. See below an example of traffic received by the switch. In that case the neighbor name as shown in CVP is "flapping" and it does not. 2022. 6. 16. · Support for the LLDP protocol is enabled on the BIG-IP system. For all BIG-IP system interfaces, the BIG-IP system attempts to transmit LLDPDUs to neighbor devices every 30 seconds, with a minimum delay between transmissions of 2 seconds. The maximum number of neighbors to which each BIG-IP system interface can send LLDPDUs is 10.

Note: for RHEL 7 the interface name doesn't contain "eth" but "enp" (or similar) to the grep should be "grep enp". Note: in case you use lldpad and wish to pass the management address via LLDP TLV on specific interface, you need to add this specifically. Otherwise, only the hostname will pass via LLDP TLV. For example:. 2021. 10. 22. · LLDP receive – Enabled; LLDP transmit Enabled; LLDP med-tlv-select – to send all LLDP-MED TLVs; LLDP Packet Format : LLDP information is transmitted and/or received by neighbor devices via each of their LLDP enabled interfaces at a fixed interval of time in the form an Ethernet frame. Each Ethernet frame contains an LLDP data unit (LLDPDU).
