| Configuring the Switch
C 4
HAPTER
Link Layer Discovery Protocol
If all ports have CDP awareness disabled, the switch forwards CDP
frames received from neighbor devices. If at least one port has CDP
awareness enabled, all CDP frames are terminated by the switch.
When CDP awareness for a port is disabled, the CDP information is not
removed immediately, but will be removed when the hold time is
exceeded.
Optional TLVs - Configures the information included in the TLV field of
advertised messages.
◆ Port Descr – The port description is taken from the ifDescr object in
RFC 2863, which includes information about the manufacturer, the
product name, and the version of the interface hardware/software.
Sys Name – The system name is taken from the sysName object in
◆
RFC 3418, which contains the system's administratively assigned
name. To configure the system name, see
Sys Descr – The system description is taken from the sysDescr object
◆
in RFC 3418, which includes the full name and version identification of
the system's hardware type, software operating system, and
networking software.
Sys Capa – The system capabilities identifies the primary function(s)
◆
of the system and whether or not these primary functions are enabled.
The information advertised by this TLV is described in IEEE 802.1AB.
Mgmt Addr – The management address protocol packet includes the
◆
IPv4 address of the switch. If no management address is available, the
address should be the MAC address for the CPU or for the port sending
this advertisement.
The management address TLV may also include information about the
specific interface associated with this address, and an object identifier
indicating the type of hardware component or protocol entity associated
with this address. The interface number and OID are included to assist
SNMP applications in the performance of network discovery by
indicating enterprise specific or other starting points for the search,
such as the Interface or Entity MIB.
Since there are typically a number of different addresses associated
with a Layer 3 device, an individual LLDP PDU may contain more than
one management address TLV.
