Link Layer Discovery Protocol Configuration
Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 protocol that can be used by a station attached to a specific LAN segment to advertise its identity and capabilities and to also receive same from a physically adjacent Layer 2 peer.
Note: Alteon sends LLDP advertisement packets, but does not support LLDP discovery. Alteon is visible to its LLDP neighbors, but does not display LLDP neighbor information.

Transmission is done on all the Alteon data ports.

The destination address is the LLDP_Multicast address 01-80-C2-00-00-0E.

The source address is the MAC address of the sending port.

The LLDP protocol contains the following mandatory fields TLVs (type-length-value):
— Chassis ID - the device's basic MAC ID
— Port ID - the Alteon port ID that the message was sent from
— Time To Live (TTL) - the amount of time this information is considered.
The value is the Tx Hold Multiplier x the Transmission Interval.
The Tx Hold Multiplier is a parameter defined by the user (range 2-20, default 4)

Radware's implementation of the LLDP protocol also includes the following vendor specific TLVs (TLV - 127) as appears in the RFC. The organizationally unique identifier (OUI) for these TLVs will be Radware's OUI (00:03:B2).
The following shows the basic format of the organizationally specific TLV.
The following lists the organizationally defined information string for specific field (subtype):
Vendor name (subtype 1): Radware

Alteon
Platform (subtype 2): The platform model. For example, Alteon 6420/XL or Alteon VX 6420
Memory size in bytes (subtype 3): Platform’s RAM size in bytes. For example, 64 GB
OS version (subtype 4): Platforms operating system version. For example, 30.5.0.0
Hypervisor (relevant for Alteon VA only) (subtype 5): VMware, KVM, Hyper-V, open-XEN, AWS or Azure
