Full Duplex Enablement Operation Example

The following example assigns an IP address and subnet mask, specifies an MII Ethernet connector, and enables full-duplex mode on Fast Ethernet interface port 0 in slot 1 port adapter 0:

Router(config)# interface fastethernet 1/0/0

Router(config-if)#ip address 1.1.1.10 255.255.255.0

Router(config-if)# full-duplex

Router(config-if)# media-type mii

Router(config-if)# exit

Router(config)# exit

PA-12E/2FE Port Configuration Examples

The following is an example of a configuration for the PA-12E/2FE port adapter interface. Bridge groups 10, 20, and 30 use IEEE Spanning-Tree Protocol. The first four interfaces of a PA-12E/2EF port adapter in port adapter slot 3 use bridge groups 10 and 20. Each interface is assigned to a bridge group and the shutdown state is set to up. The PA-12E/2FE port adapter supports store-and-forward or cut-through switching technology between interfaces within the same bridge group; store-and-forward is the default. In the following example, the cut-throughcommand is used to configure each interface for cut-through switching of received and transmitted data:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL-Z.

Router(config)# bridge 10 protocol ieee

Router(config)# bridge 20 protocol ieee

Router(config)# bridge 30 protocol ieee

Router(config)# interface fastethernet 3/0 Router(config-if)#bridge-group 10 Router(config-if)#cut-through Router(config-if)#no shutdown Router(config-if)#exit Router(config)#
