16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series
Fallback Bridging Example
This section describes how to configure fallback bridging on your switch. It contains this configuration
information:
•
•
•
•
•
Creating a Bridge Group Example
The following example shows how to create bridge group 10, specify the VLAN-bridge STP to run in
the bridge group, and assign an interface to the bridge group:
Switch(config)# bridge 10 protocol vlan-bridge
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# no switchport
Switch(config-if)# bridge-group 10
Preventing the Forwarding of Dynamically Learned Stations Example
The following example shows how to prevent the switch from forwarding frames for stations that it has
dynamically learned in bridge group 10:
Switch(config)# no bridge 10 acquire
Configuring the Bridge Table Aging Time Example
The following example shows how to change the bridge table aging time to 200 seconds for
bridge group 10:
Switch(config)# bridge 10 aging-time 200
Filtering Frames by a Specific MAC Address Example
The following example shows how to forward a frame with MAC address 0800.cb00.45e9 through an
interface in bridge group 1:
Switch(config)# bridge 1 address 0800.cb00.45e9 forward gigabitethernet0/1
