The Logical Link Control (LLC) service allows LLC frames to be sent and 
received on the MAC. LLC frames are all data frames transmitted on the 
network. If there is something wrong on your network, you may want to 
turn off data (user) traffic for a MAC by disabling LLC service. Although you 
have disabled data traffic from the MAC, the MAC still participates in 
neighbor notification and is visible to network management.

To enable or disable LLC service for the MACs in the Switch 2200:

1 From the top level of the Administration Console, enter:

You are prompted for a MAC number and to enable or disable LLC service. 
The Switch 2200 has one MAC, which appears in brackets.

2 Press Return.

3 Enter the new MAC value (

 or 

).

See the following example:

Select MAC [1]:               

MAC 1 - Enter new value (disabled,enabled) [enabled]: 

The possible backplane path assignments include primary and secondary. 

To assign MACs to paths:

1 From the top level of the Administration Console, enter:

You are prompted for a path assignment for the MAC.

2 Enter the path.
