information about using U2000 client to manage sx700 switchs

Hi,

I'm afef from satec Tunisia, we're huawei partner. we have installed recently U2000 to manage some sx700 switchs (s5700 and s7700) for our client and he wants to clarify some points about managing these switchs via U2000 client.

Mu questions are

1- how we can classify users according to their privileges for exmaple:  group of users have login and password to access to the U2000 client and they can add or delete an equipment, other group of users have another login and password and they can only access to the configuration and troubleshooting.

2- Our client wants to know how he can find via U2000 client the total number of ports for each switch, the number of ports not used, the bandwidth and how he can configure the port via U2000 client without using telnet.
