Specifies a non-default aging-time value for conversational ARP/ND.
If conversational ARP/ND is enabled (by entering the host-table aging-mode conversational command), the default aging-time value is 300 seconds.
Global configuration mode
You can modify the aging-time value either before or after enabling conversational ARP/ND.
Pre-existing entries age out using the old configured value. A changed age-time configuration applies only entries added following the change.
To restore the default aging-time value of 300 seconds, enter the no form of this command.
The following example sets the aging-time value to 600 seconds and then enables conversational ARP/ND.
device# configure terminal device(config)# host-table aging-time conversational 600 device(config)# host-table aging-mode conversational
