+==== Reset Interface to Default ====
+Here we reset a single port 'gigabitEthernet 1/13' back to defaults and set it as an access port:
+<file>
+conf t
+default interface gi1/13
+interface gi1/13
+switchport mode access
+exit
+exit
+</file>
+This is for a range of ports:
+<file>
+conf t
+default int range gi1/13,gi1/15,gi1/17,gi1/19,gi1/21
+int range gi1/13,gi1/15,gi1/17,gi1/19,gi1/21
+switchport mode access
+exit
+exit
+</file>
+===== LACP Port Bonding =====
+Configure the channel group (channel group 1 example shown here):
+<file>
+Router> enable
+Router# configure terminal
+Router(config)# interface port-channel 1
+Router(config-if)#description your_bond
+Router(config-if)#switchport
+Router(config-if)#switchport mode access
+Router(config-if)#exit
+</file>
+Configure the ports (gigabit ports 33 and 34 in this example):
+<file>
+Router(config)# interface range gi1/33-34
+Router(config-if-range)#channel-protocol lacp
+Router(config-if-range)#channel-group 1 mode active
+Router(config-if-range)#exit
+Router(config-if)# exit
+Router# show lacp internal
