298CHAPTER 19: CONFIGURING BRIDGE

2Configure 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

Operation	Command
Specify the STP version supported by the	bridge bridge-setstp ieee
bridge-set
Delete the STP version supported by the	undo bridge bridge-setstp ieee
bridge-set

By default, the bridge-set supports the STP version ieee.

3Add 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

Operation	Command
Add ports to a bridge-set	bridge-set bridge-set
Remove ports from a bridge-set	undo bridge-set bridge-set

By default, the port is not added to any bridge-set.

4Configure 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

Operation	Command
Configure static address table entries	bridge bridge-setmac-address
	mac-address{ permit deny } [
	interface-type interface-number ]
Delete static address table entries	undo bridge bridge-setmac-address
	mac-address

By default, dynamic address table is adopted to forward frames.
