Description
Specify the syslog server name and port. This feature specifies
the server for logging IP phone system information and
critical events. If both Debug Server and Syslog Server are
specified, Syslog messages are also logged to the Debug
Server.
The debug level from 0-3. The higher the level, the more
debug information is generated. Zero (0) means no debug
information is generated. To log SIP messages, you must set
the Debug Level to at least 2.
Defaults to 0.
Used for IP phone network layer debugging purposes. Do not
use except when advised to do so by Cisco technical support,
as this may impact system performance. Set to No by default.
IP address or name of primary NTP server.
IP address or name of secondary NTP server.
If enabled, the phone supports console access for debugging
and testing.
If enabled, the phone continues to use the previous cached
DNS result if the DNS server does not respond when the
phone tries to renew its DNS query.
When disabled, the phone uses the previous TTL value and
clears the DNS query result cache.
User ID for SSH login.
Password for the SSH login.
Description
Enable CDP only if you are using a switch that has Cisco
Discovery Protocol. CDP is negotiation based and determines
which VLAN the IP phone resides in.
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.
