DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Configures CDP to use only version 1 (CDPv1) in communicating with
neighboring devices.
cdp advertise v1
Example:
RP/0/RP0/CPU0:router(config)#
cdp advertise v1
Step 2
•
By default, when CDP is enabled, the router sends CDPv2 packets. CDP
also sends and receives CDPv1 packets if the device with which CDP is
interacting does not process CDPv2 packets.
•
In this example, the router is configured to send and receive only CDPv1
packets.
Specifies the amount of time that the receiving networking device will hold a
CDP packet sent from the router before discarding it.
cdp holdtime seconds
Example:
RP/0/RP0/CPU0:router(config)#
cdp holdtime 30
Step 3
•
By default, when CDP is enabled, the receiving networking device holds
a CDP packet for 180 seconds before discarding it.
The CDP hold time must be set to a higher number of seconds than
the time between CDP transmissions, which is set with the cdp
timer command.
Note
•
In this example, the value of hold-time for the seconds argument is set to
30.
Specifies the frequency at which CDP update packets are sent.
cdp timer seconds
Step 4
Example:
RP/0/RP0/CPU0:router(config)#
cdp timer 20
•
By default, when CDP is enabled, CDP update packets are sent at a
frequency of once every 60 seconds.
A lower timer setting causes CDP updates to be sent more
frequently.
Note
•
In this example, CDP update packets are configured to be sent at a frequency
of once every 20 seconds.
