1 When I use checking Rtt it displays stripchart and ping time , but in
stripchart , there is no graphs. Why do graphs disappear?
2 When I use to check "interface load" it displays stripchart , and it
display Ctron , % ( and the same thing is no graph ) . I doubt that
what is Ctron?
3 Are equipments that can send trap message HOST , BRIDGE , ROUTER ,
ETHERNET SWITCH and is it neccessary to know its community , if yes ,
ETHERNET SWITCH at my faculty has lost its manual , how should I do?

Thanks for any answer...
