298 CHAPTER 19: CONFIGURING BRIDGE
2 Configure Bridge-Set
Each bridge set is independent, and packets can not be transmitted between the
ports belonging to different bridge sets. That is, the packets received via one
bridge set port can only be sent via the ports of the same bridge set. One physical
interface can only be added to one bridge set.
The bridges support several STP versions and these versions are not compatible.
Sometimes, different STP versions may result in bridge looping.
The 3Com Router series only support the STP defined in IEEE.
Perform the following configuration in system view.
Table 321 Specify the STP version supported by the bridge-set
By default, the bridge-set supports the STP version ieee.
3 Add Ports to a Bridge-Set
One interface on the router cannot be added to more than one bridge set.
Perform the following configuration in interface view.
Table 322 Add ports to a bridge-set
By default, the port is not added to any bridge-set.
4 Configure Bridging Address Table
Bridging address table records the correlation between the destination MAC
addresses and the ports. According to it, a bridge implements forwarding.
a Configure static address table entries
Normally, a bridging table is dynamically generated according to the correlation
between the MAC addresses and the ports obtained by the bridge. However,
there are still some static entries in the bridging address table, which are
manually configured and maintained by the administrators and will not age
forever.
Perform the following configuration in interface view.
Table 323 Configure static address table entries
By default, dynamic address table is adopted to forward frames.
b Enable/Disable forwarding by using dynamic address table
