Configuring Transparent Bridging

Transparent and SRT Bridging Configuration Task List

To specify deny or permit conditions for LAT groups on input, use one of the following commands in interface configuration mode:

Command

Purpose

 

 

bridge-group bridge-group

Specifies the group codes with which to deny access upon input.

input-lat-service-deny group-list

 

 

 

bridge-group bridge-group

Specifies the group codes with which to permit access upon input.

input-lat-service-permit group-list

 

 

 

If a message specifies group codes in both the deny and permit list, the message is not bridged.

Specifying Deny or Permit Conditions for LAT Group Codes on Output

You can specify the group codes by which to deny or permit access upon output. Specifying deny conditions causes the system to not bridge onto the output interface any LAT service advertisements that contain any of the specified groups. Specifying permit conditions causes the system to bridge onto the output interface only those service advertisements that match at least one group in the specified group list.

To specify deny or permit conditions for LAT groups on output, use one of the following commands in interface configuration mode:

Command

Purpose

 

 

bridge-group bridge-group

Specifies the group codes with which to deny access upon output.

output-lat-service-deny group-list

 

 

 

bridge-group bridge-group

Specifies the group codes with which to permit access upon output.

output-lat-service-permit group-list

 

 

 

If a message matches both a deny and a permit condition, it will not be bridged.

Adjusting Spanning-Tree Parameters

You might need to adjust certain spanning-tree parameters if the default values are not suitable for your bridge configuration. Parameters affecting the entire spanning tree are configured with variations of the bridge global configuration command. Interface-specific parameters are configured with variations of the bridge-groupinterface configuration command.

You can adjust spanning-tree parameters by performing any of the tasks in the following sections:

•Setting the Bridge Priority

•Setting an Interface Priority

•Assigning Path Costs

•Adjusting BPDU Intervals

•Disabling the Spanning Tree on an Interface
