Somebody can tell me why the bandwidth is set to 2Mb in Mac object. (ns-mac.tcl) and 10 Mb in Phy/WiredPhy object (wired-phy.cc)? (see current Ns release) Theses values are never changed (I don't find this instruction in vlan.tcl) and the bandwidth is set hardly in wired-phy.cc (see my previous mail). What I have wrong ? Thanks in advance P. ANELLI
