[c-nsp] Enabling CFM globally on a 7600

[Christophe Fillot]

Hello,

I would like to run CFM on a Cisco 7600 (IOS 15.1(2)S), but when I use 
the command "ethernet cfm global", I get the following message:

Apr 21 11:00:56.519: %CFM_CONST-SP-3-MATCH_REG_GLOBAL_RESERVE_FAILED: 
Unable to program port ASIC MAC match register on one or more slots. 
Cannot run CFM

On the CCO, the recommended action is "To free MAC match registers, 
disable protocols that use the MAC match register. Protocols using port 
ASIC match registers can be viewed with the remote command switch show 
platform mrm info command."

# remote command switch show platform mrm info

Match Register Usage
  slot 1 has 3 mr and is online
    mr 1: bits 1 (prog) owner SSTP
    mr 2: bits 1 (prog) owner FREE
    mr 3: bits 1 (prog) owner FREE
  slot 2 has 0 mr and is offline
  slot 3 has 0 mr and is offline
  slot 4 has 2 mr and is online
    mr 1: bits 0 (48  ) owner SSTP
    mr 2: bits 2 (44  ) owner FREE
  slot 5 has 2 mr and is online
    mr 1: bits 0 (48  ) owner SSTP
    mr 2: bits 2 (44  ) owner FREE
  slot 6 has 2 mr and is online
    mr 1: bits 0 (48  ) owner SSTP
    mr 2: bits 2 (44  ) owner FREE

I only want to enable CFM on a specific port of the linecard installed 
in slot 1 (WS-X6748-GE-TX).
 From what I can read of the previous output, it seems there are free 
registers available.

I tried to disable CFM on all ports excepted the one I'm interested in, 
but no luck.
Has someone any idea ?

Thanks in advance,

Christophe
