A Routing Information Field (RIF) is stored for each MAC address learned on a token ring 
port. One RIF is stored for each MAC address. The maximum size of each RIF is 32 bytes 
(long enough to traverse 15 bridge hops) 

Once a RIF is learned for a MAC address, it is maintained until the MAC address is aged out 
of the CAM. You can view a list of RIFs using the 

 command. To view the RIF table 

follow these steps:

1. Enter the 

 command at the menu prompt. The following prompt is displayed:

The following section describes the fields shown using the 

 command.

. This field lists the slot, port number, service type, and instance number for where the 

RIF was learned for this MAC address. 

. The group number with which this RIF is associated.

. The MAC address for this RIF. It is shown in non-canonical form.

. The index number in the Content-Addressable Memory (CAM), where the MAC 

addresses are stored, in hexadecimal form.

. The length of the RIF packet, in bytes.
