In this case, only one RRPP domain is to be defined, inwhich one ring must be defined as the primary ring and the rest as subrings.1.1.5 RRPP on H3C S7500 Series Ethernet SwitchesTo employ RRPP on an S7500 series Ethernet switch, make sure that:z The chassis comes with the silk print XGbus.z For H3C S7503/S7506/S7506R switches, Salience III series SRPUs (includingSalience III, Salience III Plus, and Salience III Edge) are used. Besides, BootROMversion 527 (or later) is used.z For H3C S7502 switches, the CPLD version of the SRPU is not lower than 005.z The CPLD version of the LPUs is not lower than 005.Ports that support RRPP are:z The four Gigabit SFP ports on Salience III Edge/ Salience III enginez Gigabit SFP ports/10 Gigabit ports on LS81T12PE, LS81P12TE, LS81GP8UB,LS81TGX2, LS81TGX4, LS81T32P, LS81T16P, and LS81GP48 LPUs.
