Parameter
Enable LLDP-MED
Network Startup Delay
Description
Choose yes to enable LLDP-MED for the phone
to advertise itself to devices that use that
discovery protocol. (By default, this setting is
enabled.)
When the LLDP-MED feature is enabled, after
the phone has initialized and Layer 2
connectivity is established, the phone sends
out LLDP-MED PDU frames. If the phone
receives no acknowledgment, the manually
configured VLAN or default VLAN is used if
applicable. If CDP is used concurrently, a
waiting period of 6 seconds is used. The
waiting period increases the overall startup
time for the phone.
Enter the delay in seconds for the switch to get
to the forwarding state before the phone sends
out the first LLDP-MED packet. The default
delay is 3 seconds. For configuration of some
switches, it might be necessary to increase this
value to a higher value for LLDP-MED to work.
Configuring a delay can be important for
networks that use Spanning Tree Protocol.
