4| Ethernet Bridge and VLANs
For example, create VLAN learning constraints so that Shared VLAN Learning is used between the default,
data and video VLANs and Independent VLAN Learning is used between the video and voice VLAN:
Listing all VLAN learning constraints
To list all VLAN learning constraints, execute following command:
Deleting a VLAN learning constraint
To delete a VLAN learning constraint, use the command
:eth bridge rule delete
.
One parameter must be specified:
Index : this parameter indicates the index of the VLAN learning constraint to be deleted.
For example, delete the first two VLAN learning constraints as follows:
Flushing all VLAN learning constraints
To delete all VLAN learning constraints at once, execute following command:
=>:eth bridge rule add type=shared vlan=data vlan2=default
=>:eth bridge rule add type=shared vlan=video vlan2=default
=>:eth bridge rule add type=independent vlan=video isi=0
=>:eth bridge rule add type=independent vlan=voice isi=0
Be careful during the creation of VLAN learning constraints, as inconsistencies are not always
reported by the Thomson Gateway.
=>:eth bridge rule list
Index Type VLAN Parameter
----- ---- ---- ---------
1 shared data Shared with VLAN: default
2 shared video Shared with VLAN: default
3 independent video Independent set identifier: 0
4 independent voice Independent set identifier: 0
If the list has no entry for a specific VLAN, Independent VLAN learning (IVL) is being used implicitly.
=>:eth bridge rule delete index=1
=>:eth bridge rule delete index=2
=>:eth bridge rule list
Index Type VLAN Parameter
----- ---- ---- ---------
3 independent video Independent set identifier: 0
4 independent voice Independent set identifier: 0
Before deleting a constraint, list all VLAN learning constraints to obtain the correct index of the
constraint to be deleted.
=>:eth bridge rule flush
=>:eth bridge rule list
