Traditionally, CRS and REM functions are implemented in the bridges. However,
the 8260 T-MAC implements the CRS and REM functions, which provides you
with the following functions:
•
Collect soft error statistics
•
Analyze soft error statistics
•
Collect Beaconing statistics
•
Analyze Beacon frames
•
Report Beacon conditions and resolutions
•
Report REM MAC frames
•
Provide ring station configuration information
•

10.7.1 Using T-MAC Surrogate Functions
To be able to use the T-MAC surrogate functions, you must do the following:
1. Enable the surrogate features
2. Enable the individual surrogate groups
10.7.1.1 Enabling Surrogate Features
Enabling the surrogate feature on the T-MAC results in the Ring Error Monitor
(REM) and Configuration Report Server (CRS) functions of the T-MAC to be
activated. To enable the surrogate features you must do the following:
1. Enable the surrogate function
You can use either of the following commands to enable the surrogate
function:
SET MODULE {slot.subslot} SURROGATE_GROUP enable or
SET TR_SURROGATE {slot.subslot} SURR_STATUS SURR_ADMIN enable
Note: Surrogate function must be enabled before you can enable the CRS or
REM function.
2. Enable the REM feature using the following command:
SET TR_SURROGATE {slot.subslot} SURR_STATUS REM_ADMIN
3. Enable the CRS feature using the following command:
SET TR_SURROGATE {slot.subslot} SURR_STATUS CRS_ADMIN
4. Enable the Surrogate Ring feature using the following command:
SET TR_SURROGATE {slot.subslot} SURR_STATUS RING_SEGMENT
You may display the status of the surrogate features using the following
command:
SHOW TR_SURROGATE {slot.subslot} SURR_STATUS
An example of the output from this command is shown in Figure 133 on
page 234.
