Disabling And Enabling Ip Mls On A Layer 3 Interface; Displaying The Interface Ip Mls Configuration - Cisco 6500 Series Software Configuration Manual

Chapter 19 Configuring IP Unicast Layer 3 Switching on Supervisor Engine 1

Disabling and Enabling IP MLS on a Layer 3 Interface

IP MLS is permanently enabled globally but can be disabled and enabled on a specified interface.
To enable IP MLS on a specific interface, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID} |
1
{type slot/port} | {port-channel number}}
Step 2
Router(config-if)# mls ip
Router(config-if)# no mls ip
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to disable IP MLS for Fast Ethernet port 5/5:
Router(config)# interface fastethernet 5/5
Router(config-if)# no mls ip
Router(config-if)#
IP MLS is enabled by default; you only need to enable it if you have previously disabled it.
Note
