LAN Interface Configuration Examples

IC-62

Cisco IOS Interface Configuration Guide

Router(config)# interface ethernet 3/2

Router(config-if)# bridge-group 20

Router(config-if)# cut-through

Router(config-if)# no shutdown

Router(config-if)# exit

Router(config)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet3/2, changed state to up

%LINK-3-UPDOWN: Interface Ethernet3/2, changed state to up

Router(config)# interface ethernet 3/3

Router(config-if)# bridge-group 20

Router(config-if)# cut-through

Router(config-if)# no shutdown

Router(config-if)# exit

Router(config)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet3/3, changed state to up

%LINK-3-UPDOWN: Interface Ethernet3/3, changed state to up

The following example shows integrated routing and bridging enabled on the bridge groups. Bridge

group 10 is assigned an IP address and subnet mask and the shutdown state is changed to up. Bridge

group 10 is configured to route IP.

Router(config)# bridge irb

Router(config)# interface bvi 10

Router(config-if)# ip address 1.1.15.1 255.255.255.0

Router(config-if)# no shutdown

Router(config-if)# exit

Router(config)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface BVI10, changed state to up

Router(config)# bridge 10 route ip

Router(config)# exit

Router#

PA-VG100 Port Adapter Configuration Example

The following is an example of a basic configuration for the PA-VG100 port adapter interface in slot 1

on a Cisco 7500 series router. In this example, IP routing is enabled on the router, so an IP address and

subnet mask are assigned to the interface.

configure terminal

interface vg-anylan 1/0/0

ip address 1.1.1.10 255.255.255.0

no shutdown

exit

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 46
