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
