set dhcpsnooping checkinterval
Syntax SET DHCPSnooping CHEckinterval=1..3600
Description This command sets a check interval for the DHCP snooping binding database.
This determines how often dynamic database entries are checked for
expiration. Static entries defined with the add dhcpsnooping binding
command on page 14 are not checked.
The checkinterval parameter specifies the number of seconds between checks.
The default interval is 60 seconds.
When the switch checks the database, it automatically deletes any expired
entries from the database. An entry is considered expired if the time left to
expiry is 0 seconds. The switch writes all dynamic entries remaining in the
database after each check to the bindings.dsn file. Whenever you enable DHCP
snooping using the enable dhcpsnooping command on page 18, the switch
recreates the DHCP snooping binding database, and adds any entries that are
still current to the database.
Defining a smaller check interval ensures greater security, as expired entries are
removed closer to their actual expiry time.
Defining a longer check interval reduces CPU usage, as the database is checked
less often.
Examples To set the check interval to 3 minutes, use the command:
set dhcps che=180
