Q: Does MA5200F/G at versions support auto-negotiation of PAP/CHAP of PPP?
1. MA5200F starts to support it from MA2.10-7131;
2. MA5200G starts to support it from VRP3.30-2117, and the early versions do not support it. The command of both MA5200F and MA5200G are configured in the virtual template, for instance:
[MA5200F-Virtual-Template1]ppp authentication-mode <auto|pap|chap>
[MA5200G-Virtual-Template1]ppp authentication-mode <auto|pap|chap>
Of which auto mode will auto-negotiate to PAP or CHAP according to the authentication mode of clients under MA5200F/G
