IP DNS FORWARDING CACHE

ip dns forwarding cache
Overview Use this command to set the DNS Relay name resolver cache size and cache entry
lifetime period. The DNS Relay name resolver cache stores the mappings between
domain names and IP addresses.
Use the no variant of this command to set the default DNS Relay name resolver
cache size and cache entry lifetime period.
Note that the lifetime period of the cache entry can be overwritten by the time-out
period of the DNS reply from the DNS server if the time-out period of the DNS reply
from the DNS server is smaller than the configured time-out period. The time-out
period of the cache entry will only be used when the time-out period of the DNS
reply from the DNS server is bigger than the time-out period configured on the
device.
