| count | Specifies the number of times the switch transmits LLDP MED TLVs each second (once it detects a neighbor transmitting LLDP MED TLVs). The range is 1 to 10. |
3.
When the switch detects a MED-capable device, this count determines how many times the switch sends a LLDP MED TLVs with an interval of 1 second. The fast-start feature enables the MED-capable device to quickly learn information; this command changes the value from the default 3. The fast-start feature is automatically enabled when you enable the LLDP MED capabilities TLV.
Note
After you configure the LLDP MED capability TLV, the fast-start feature automatically runs. To configure the LLDP MED capability TLV, use the configure lldp ports [all | port_list] [advertise | no-advertise] vendor-specific med capabilities command.
The following command configures fast learning on the switch to a value of 2:
configure lldp med fast-start repeat-count 2
