Support for Hardware-based 100ms CCM Timers for G.8032 MEPs

On 7210 SAS-X and 7210 SAS-R6, the user needs to reserve a VLAN-ID for use with only
G.8032 MEPs which uses the hardware for CCM processing. No data services or control SAPs can
use this VLAN-ID. The CLI command description used to reserve the VLAN-ID is available in the
7210 SAS-M,T,X,R6 Interfaces guide.
NOTE: Prior to release 4.0, in 7210 SAS-X devices, the G.8032 MEPs were supporting 100ms
CCM timers but implementation was in software. From release 4.0 release onwards hardware
implementation of 100ms CCM timers is available for use with G.8032 only.
When using hardware CCMs, a limited amount of control instances is supported per port. Multiple
data services/instances can be associated with each of these control instances.
Sample configuration with "control-sap-tag" command:
