2. After configured, the sub ring status is preforwarding on S7700
RRPP Ring : 2
Ring Level : 1
Node Mode : Edge Transit
Ring State : PreForwarding
Is Enabled : Enable Is Active: Yes
Primary port : Ethernet2/0/2 Port status: UP
Ethernet2/0/3 Port status: UP
Secondary port : Ethernet2/0/5 Port status: BLOCKED
Check all configuration on device. Found that RRPP working-mode is GB on S7700, but on S57 it is HW mode. Because of different mode, there are different node and configuration on Switch.
Let customer change RRPP working-mode to HW same with S5700 and test it works fine.
1. Wrong Configuration
2. RRPP calculation Issue
1. Changing RRPP working-mode needs to disable RRPP first and delete the old configuration
2. On S5700, RRPP only supports HW working-mode and cannot be configured. S7700 supports both modes.
