Following figure displays the global configuration settings for the bridge. 

 

The following bridge information is displayed: 

1. 

Bridge MAC Address 

2. 

Number of bridge interfaces configured 

3. 

Type of the Bridge 

4. 

Unicast learning which is non-configurable, and always set to Hybrid, i.e. VLAN learning 
is both “Independent” as well as “Shared” depending on the association of VLANS with 
filtering databases. 

5. 

Multicast Learning setting which is non-configurable and always set to HVM(Hybrid 
VLAN Multicast Learning), i.e. if two VLANs are associated with the same FDB, the 
filtering information for a multicast MAC address in one VLAN would be used in the 
forwarding decision for the same MAC address in the other VLAN too. 

6. 

Config Pvid Status which is non-configurable and is always true, i.e. the bridge supports 
the ability to override the default PVID setting and its egress status (VLAN tagged or 
untagged) on each bridge interface. 

7. 

Tagging which is non-configurable and always enabled, i.e. each bridge interface 
supports 802.1Q VLAN tagging of frames. 

8. 

AcceptableFrameTypeCfg which is non-configurable and always enabled, i.e. each 
bridge interface can be configured to accept all frames or only tagged frames. 

9. IngressFilteringCfg 

which 

is 

non-configurable and is always enabled, i.e. each bridge 

interface supports discarding of frames whose VLAN classification does not include that 
interface in its member set. 

10.  Filter Age is the time (in seconds) after which MAC addresses are removed from the 

filter table when there has been no activity. The time may be an integer value between
