Usage Guidelines
When you enable LLDP globally using the lldp command, LLDP is not enabled on subinterfaces or bundle
subinterfaces by default. This is to prevent the LLDP process from consuming high CPU cycles. In order to
enable LLDP on subinterfaces and bundle subinterfaces as well, the lldp subinterfaces enable command is
introduced.
When you use this command, you must remember that as the scale of interfaces(with subinterfaces and
Note
bundle subinterfaces) becomes higher, it might cause the LLDP process to hog the CPU.
