Task Command

Remarks

display ip count rule [ | { begin | exclude |
include } regular-expression ]

Display IP accounting rules.

Available in any view.

display ip count { inbound-packets |
outbound-packets } { exterior |

firewall-denied | interior } [ | { begin |

exclude | include } regular-expression ]

Available in any view.

Display IP accounting statistics.

reset ip count { all | exterior | firewall |
interior }

Clear IP accounting statistics.

Available in user view.

After you create a new IP accounting rule, it is possible that some originally rule-incompliant packets from

a subnet comply with the new rule. Information about these packets is then saved in the interior table. The

exterior table, however, might still contain information about the IP packets from the same subnet.

Therefore, in some cases, the interior and exterior tables contain statistics about the IP packets from the

same subnet. The statistics in the exterior table will be removed when the timeout time expires.
