Description
If you use a VLAN without Cisco Discovery Protocol
(CDP) (VLAN enabled and CDP disabled), enter a VLAN
ID for the IP phone. Note that only voice packets are
tagged with the VLAN ID. Do not use 1 for the VLAN ID.
Enable CDP only if you are using a switch that has CDP.
CDP is negotiation-based and determines on which VLAN
the IP phone resides.
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.
