LLDP and LLDP-MED Standards Compatibility

The operation covered by this section is compatible with these standards:
IEEE P802.1AB/D9 (Series 3400cl switches)
■
■ IEEE P802.1AB (Series 5300xl, Series 4200vl, and Series 6400cl switches)
■ RFC 2922 (PTOPO, or Physical Topology MIB)
RFC 2737 (Entity MIB)
■
■ RFC 2863 (Interfaces MIB)
■ ANSI/TIA-1057/D6 (LLDP-MED; refer to "LLDP-MED (Media-Endpoint-
Discovery) for the 5300xl and 4200vl Switches" on page 15-44.)

LLDP Operating Rules

(For additional information specific to LLDP-MED operation, refer to "LLDP­
MED (Media-Endpoint-Discovery) for the 5300xl and 4200vl Switches" on
page 15-44.)
Port Trunking. LLDP manages trunked ports individually. That is, trunked
ports are configured individually for LLDP operation, in the same manner as
non-trunked ports. Also, LLDP sends separate advertisements on each port in
a trunk, and not on a per-trunk basis. Similarly, LLDP data received through
trunked ports is stored individually, per-port.
IP Address Advertisements. In the default operation, if a port belongs to
only one static VLAN, then the port advertises the lowest-order IP address
configured on that VLAN. If a port belongs to multiple VLANs, then the port
advertises the lowest-order IP address configured on the VLAN with the
lowest VID. If the qualifying VLAN does not have an IP address, the port
advertises 127.0.0.1 as its IP address. For example, if the port is a member of
the default VLAN (VID = 1), and there is an IP address configured for the
default VLAN, then the port advertises this IP address. In the default operation,
the IP address that LLDP uses can be an address acquired by DHCP or Bootp.
You can override the default operation by configuring the port to advertise
any IP address that is manually configured on the switch, even if the port does
not belong to the VLAN configured with the selected IP address (page 15-41).
(Note that LLDP cannot be configured through the CLI to advertise an
addresses acquired through DHCP or Bootp. However, as mentioned above,
in the default LLDP configuration, if the lowest-order IP address on the VLAN
