Network Startup Delay
Cisco IP Phone 8800 Series Multiplatform Phone Administration Guide for Release 11.3(1) and Later
VLAN Settings Parameters
Description and Default Value
Choose Yes to enable LLDP-MED for the phone to
advertise itself to devices that use that discovery
protocol.
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 will
be used if applicable. If the CDP is used concurrently,
the waiting period of 6 seconds is used. The waiting
period will increase the overall startup time for the
phone.
• In the phone configuration file with
XML(cfg.xml), enter a string in this format:
<Enable_LLDP-MED
ua="na">Yes</Enable_LLDP-MED>
• In the phone web interface, set to Yes to enable
LLDP-MED.
Valid values: Yes/No
Default: Yes
Setting this value causes a delay for the switch to get
to the forwarding state before the phone will send out
the first LLDP-MED packet. The default delay is 3
seconds. For configuration of some switches, you
might need 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.
• In the phone configuration file with
XML(cfg.xml), enter a string in this format:
<Network_Startup_Delay
ua="na">3</Network_Startup_Delay>
• In the phone web interface, enter the delay in
seconds.
Valid values: An integer ranging from 1 through 300
Default: 3
