Figure 21 LLDP Internal Architecture for a Network Node
Network operators must be able to discover the topology information in order to
detect and address network problems and inconsistencies in the configuration.
Standards-based tools can address complex network scenarios where multiple
devices from different vendors are interconnected using Ethernet interfaces.
The 7705 SAR platforms, cards, and modules support LLDP on all Ethernet datapath
ports. On the 2-port 10GigE (Ethernet) Adapter card/module, LLDP is supported on
the Ethernet ports, but not on the v-port. Each Ethernet port can be configured to run
up to three LLDP sessions. Each session can have up to five peers and each peer
can store up to three management addresses.The 7705 SAR can have a maximum
of 720 peers configured.
Figure 22 shows the three scopes of LLDP that are supported on the 7705 SAR. The
scopes are Nearest Bridge, Nearest non-TPMR Bridge, and Nearest Customer
Bridge.
