LLDP-MED configuration
8
Brocade(config)#lldp enable snmp med-topo-change-notifications ports e 1/1/1 to
1/1/5
Syntax: no lldp enable snmp med-topo-change-notifications ports ethernet
<stack-unit>/<slot>/<port>| all
Specify the ethernet port in the <stack-unit>/<slot>/<port> format. Stack-unit is 1.
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually. Note that using the keyword all may cause undesirable
effects on s ome port s. For exam ple, if you configure all ports to advertise their VLAN name, and the
configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
Changing the fast start repeat count
The fast start feature enables a Network Connectivity Device to initially advertise itself at a faster
rate for a limited time when an LLDP-MED Endpoint has been newly detected or connected to the
network. This feature is important where rapid availability is crucial for applications such as
emergency call service location (E911).
The fast start timer starts when a Network Connectivity Device receives the first LLDP frame from a
newly detected Endpoint.
The LLDP-MED fast start rep eat count specifies the number of LLDP packets that will be sent
during the LLDP-MED fast start period. By default, the device will send three packets at
one-second intervals. If desired, you can change the number of packets the device will send per
second, up to a maximum of 10.
NOTE
The LLDP-MED fast start mechanism is only intended to run on links between Network Connectivity
devices and Endpoint devices. It does not apply to links between LAN infrastructure elements,
including between Network Connectivity devices, or to other types of links.
To change the LLDP-MED fast start repeat count, enter commands such as the following.
Brocade(config)#lldp med fast-start-repeat-count 5
The above command causes the device to send five LLDP packets during the LLDP-MED fast start
period.
Syntax: [no] lldp med fast-start-repeat-count <value>
where value is a number from 1 to 10, which specifies the number of packets that will be sent
during the LLDP-MED fast start period. The default is 3.
