Configures a minimum time-to-live (TTL) value for Layer 7 policy/application signature.
| app-signature | Specifies configuring application signature settings. |
| minimum-ttl | Specifies setting override to low DNS-reply TTL values with a minimum value. The default is none, which specifies not overriding the TTL values. |
| none | Specifies not overriding DNS-reply TTL values (default). |
| 1 | Specifies a minimum TTL of 1 minute. |
| 5 | Specifies a minimum TTL of 5 minutes. |
| 10 | Specifies a minimum TTL of 10 minutes. |
By default, the DNS-reply TTL values are not overridden (none).
To view the TTL minimum value set by this command, use the show policy app-signature command.
The following example sets a minimum TTL of 5 minutes:
# configure policy app-signature minimum-ttl 5
This command was first available in ExtremeXOS 30.5.
