The parameter is available only when CPRI port is set to structure-aware mode. This command indicates rate of slow C&M channel in CPRI link. When slow C&M is not supported by setting <rate-id> = 0, no slow C&M RoE flow is needed. RoE entity has 1 mapper and demapper reserved for RoE slow C&M flow. <rate-id> definition corresponds to CPRI standard Z.66.0 definition. This value is used to set Z.66.0 in CPRI egress. 0 = HDLC disable 1 = 240kbps 2 = 480kbps 3 = 960kbps 4 = 1920kbps 5 = 2400kbps 6 = 3840/4800/7680kbps based on CPRI-5/6/7 and higher rates 7 = follow CPRI slow C&M negotiation Note: <rate-id> should be provisioned after CPRI rate is already provisioned. Error should be issued when <rate-id> is set to a value which is invalid for a specific CPRI rate according to CPRI standard Z.66.0 definition. For example, setting <rate-id> = 5 is invalid for CPRI-3 rate.
