Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands

When you are routing Open Shortest Path First (OSPF), ensure that all secondary addresses of an

interface fall into the same OSPF area as the primary addresses.

If your switch receives its IP address from a Bootstrap Protocol (BOOTP) or a DHCP server and you

remove the switch IP address by using the no ip address command, IP processing is disabled, and the

BOOTP or the DHCP server cannot reassign the address.

A Layer 3 switch can have an IP address assigned to each routed port and SVI. The number of routed

ports and SVIs that you can configure is not limited by software; however, the interrelationship between

this number and the number of other features being configured might have an impact on CPU utilization

due to hardware limitations. You can use the sdm prefer global configuration command to reallocate

system hardware resources based on templates and feature tables. For more information, see the

This example shows how to configure the IP address for the Layer 2 switch on a subnetted network:

Switch(config)# interface vlan 1

Switch(config-if)# ip address 172.20.128.2 255.255.255.0

This example shows how to configure the IP address for a Layer 3 port on the switch:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# no switchport

Switch(config-if)# ip address 172.20.128.2 255.255.255.0

You can verify your settings by entering the show running-config privileged EXEC command.
