To clear an IP MLS cache entry, perform this task:
Command
Router# clear mls [exclude protocol [all port 1-96 |

destination ip_address | flow [tcp [any | interface |
macd | macs] | udp [any | interface | macd | macs]] |
interface {{vlan vlan_ID} | {type
{port-channel number}} | macd dest_mac_address | macs
source_mac_address | multicast | source]]
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

Displaying the IP MLS Contention Table
The show mls table-contention command displays the flow contention level. The table contention level
(TCL) is indicated with a number ranging from 0 (normal) to 3 (maximum). When reaching levels 1
through 3, accelerated aging starts, and begins to age out entries at a rate suitable to reduce the current
contention rate. The detailed option displays the breakdown of contention between different flows.
