Page 1145 highlights
• LLDP has a limited TLV size. As a result, information that is carried by this new TLV is limited to only one or two MAC addresses. • You must ensure proper configuration and physical setup on all related systems. LLDP Organizational TLV for Proxy Gateway Define a new organizational TLV : • LLDP defines an organizationally specific TLV (type 127) with an organizationally unique identifier (0x0001E8) and organizationally defined subtype (0x01) for sending or receiving this information. • LLDP will uses the existing infrastructure and adds the new TLV, and sends and receives only on the configured ports. • There are only a couple of MAC addresses for each unit to transmit so all currently active MAC addresses are carried on the newly defined TLV. • This TLV is recognizable only by Dell Networking devices with this feature support. Other devices ignore this field and are able to process other standard TLVs. The LLDP organizational TLV passes local destination MAC address information to peer VLT domain devices so they can act as the proxy gateway. Two configurations are required to enable Proxy Gateway LLDP: • Global proxy gateway LLDP configuration to enable this feature • Interface proxy gateway LLDP configuration to enable/disable proxy-gateway LLDP TLV on particular interfaces • The interface is typically a VLT port-channel which connects to a remote VLT domain • The new proxy gateway TLV is carried on the physical links under the port channel only • There should be at least one link connection to each unit of the VLT domain Following are the prerequisites for Proxy Gateway LLDP configuration: • LLDP must be globally enabled • No interface- level LLDP disable CLIs on the interfaces configured for proxy gateway, and you must enable both transmission and reception • You must connect both units of the remote VLT domain by the port channel member. • If you connect more than one port to a unit of the remote VLT domain, it must be completed by the time you enable the proxy gateway LLDP • You cannot have other conflicting configurations (for example, the no static proxy gateway configuration) This feature might not operate properly if one of the following conditions is true: • Any proxy gateway configuration or LLDP configuration is not working • LLDP packets fail to reach the remote VLT domain devices (due to system down, rebooting, port down or physical link connection) VLT Proxy Gateway 1145
