The following example shows an error message you receive if you try to configure an interface with an
IP address that is not the master interface:
Router(config-if)# cable bundle 5
Please remove ip address config first then reenter this command
To display the forwarding table for a specified interface, use the show cable bundle command in
privileged EXEC mode. A sample is shown below:
Router# show cable bundle 25 forwarding-table
MAC address
0050.7366.17ab
0050.7366.1803
0050.7366.1801
The following example shows how to bundle a group of physical interfaces. In this example, the
interfaces
int c5/0
ip address 209.165.200.225 255.255.255.0
ip address 209.165.201.1 255.255.255.0 secondary
cable helper-address 10.5.1.5
! MAC level configuration
cable bundle 1 master
int c4/0
! No IP address
! MAC layer configuration only
cable bundle 1
The following example shows how to configure interface 25 to be the master interface:
Router(config-if)# cable bundle 25 master
Router(config-if)#
07:28:17: %UBR7200-5-UPDOWN: Interface Cable3/0 Port U0, changed state to down
07:28:18: %UBR7200-5-UPDOWN: Interface Cable3/0 Port U0, changed state to up
The following example shows the error message you get if you try to configure an interface
with an IP address that is not the master interface:
Router(config-if)# cable bundle 5
