Hi.. Daniel and Dear all, Thanks for guiding me, but I still have a bit more question to consult you if you were free. 1) since the the following vlan are not in used, can I clear them? set vlan 1002 name fddi-default type fddi mtu 1500 said 101002 state active set vlan 1004 name fddinet-default type fddinet mtu 1500 said 101004 state active stp ieee set vlan 1005 name trnet-default type trbrf mtu 1500 said 101005 state active stp ibm 2) If set trunk 3/5 means that a trunk can never be established on this link, but is it a must to specify that. Is that the default? Can I clear them? I saw the configuration of the each module like set vlan XXX set port speed XXX set trunk XXXX on isl 1-1005 set trunk xxxx off negiotiate 1-1005-----(1) set spantree portfast set spantree portcost----- (2) set spantree portvlancost xx cost YYYY ----- (3) May I know whether no 1) 2) 3) are created by default?? Can I clear them?? 3)What is the different between auto negiotiate and off negiotiate ?? off isl and on isl Thank you very much.. sorry for disturbing you..
