To show the link-related status of a bridge:
```
# dladm show-bridge -l bridge-name
```
To show link-related statistics for the bridge:
```
# dlstat show-bridge bridge-name
```
To show kernel forwarding entries for the bridge:
```
# dladm show-bridge -f bridge-name
```
To show TRILL information about the bridge:
```

The following examples show how to use the dladm show-bridge command with various options.

The following command shows link-related status information for a single bridge instance, tower. To view configured properties, use the dladm show-linkprop command.

# dladm show-bridge -l tower
LINK         STATE        UPTIME   DESROOT
net0         forwarding   117      8192/0:d0:0:76:14:38
net1         forwarding   117      8192/0:d0:0:76:14:38

The following command shows the kernel forwarding entries for the specified bridge, avignon:

# dladm show-bridge -f avignon
