1. There is one command : set group address hidden. may query what is the hidden command for? if the configuraiton is right, can it shown in the config file?
2. in the Envar Variable, the nsrp-max-cluster=16, however, even the envar is setup , the max cluster is still 7 (5.4.r16. 0+ns25) , may advise the reason why the envar is failure?
