Configuring Physical Layer 3 Interfaces

Switch#

Switch# show run interface vlan 1

interface Vlan1
ip address 10.0.0.1 255.0.0.0
counter ipv4
end
Note To remove the counters, use the no counter command.
If you have already assigned the maximum number of counters, the counter command fails and displays
an error message:
Switch# config terminal
Enter configuration commands, one per line.
Switch(config)# interface fa3/2
Switch(config-if)# no switchport
Switch(config-if)# counter ipv6
Counter resource exhausted for interface fa3/2
Switch(config-if)# end
Switch#

In this situation, you must release a counter from another interface for use by the new interface.
Configuring Physical Layer 3 Interfaces
Before you can configure physical Layer 3 interfaces, you must enable IP routing if IP routing is
Note
disabled, and specify an IP routing protocol.
To configure physical Layer 3 interfaces, perform this task:
Command
Step 1
Switch(config)#ip routing
Step 2
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet} slot/port}
| {port-channel port_channel_number}
Step 3
Switch(config-if)#no switchport
Step 4
Switch(config-if)# ip address ip_address
subnet_mask
Step 5
Switch(config-if)# no shutdown
Step 6
Switch(config-if)# end
