The parameter is available only when CPRI port is set to structure-aware mode. Specifies p-pointer value for the fast C&M channel in CPRI link associated with the RoE entity. p-pointer defines the fast C&M channel region (starting subchannel) inside the CPRI control word. Based on CPRI rate and p-pointer value, the fast C&M Ethernet rate is also defined. Value = 0 means fast C&M channel is not used in CPRI link. This parameter can be modified only when roe is shutdown. And the modification of this parameter may cause traffic interrupt and need to modify it in both roe mapper and demapper so that the new value can work. 1 set of mapper and demapper (ID = 66) is reserved for handling fast C&M channel in CPRI link. Native Ethernet packet (instead of RoE packet) is used to transport fast C&M channel content. p-pointer value specifies the fast C&M channel region inside the CPRI link control word. RoE mapper then searches for the Ethernet packet content (start with SSD sequence, end with ESD sequence) inside this region and transports the entire Ethernet packet content as is. After reception of an Ethernet packet into the associate demapper (buffer queue), demapper plays out the Ethernet packet content from buffer queue sequentially into the fast C&M channel region. Demapper automatically inserts idle sequence (ie inter-packet gap) between Ethernet packets into fast C&M channel. Default value for this attribute is 0.
