Global configuration mode

The system description is the network entity, which can include information such as the product name or model number, the version of the system hardware, the software operating system level, and the networking software version. The information corresponds to the sysDescr MIB object in MIB-II.

You can specify a list of ports, separated by a space, or a range of ports, or you can combine lists and ranges.

The command cannot support LAG virtual interfaces. Attempting to configure them will have no effect.

The no form of the command disables the advertisement.

The following example advertises the system description information. 

device(config)# lldp advertise system-description ports ethernet 1/1/1 to 1/1/5
