IEWB Physical Topology Cat3550 Trunk Problem
Hi,
I tried to hook up my gears again to start lab preparation. I followed IEWB physical topology and weired,
SW1 only port fa0/16-18 can up as trunk with SW3; port f10/13-15, 19-21 showed “notconnect”; SW2 only port fa0/16-18 can up as trunk with SW3, port f10/13-15, 19-21 showed “notconnect”; SW3 only port fa0/13-15, 19-21 up as trunk with SW1 and SW4, port f10/16-18 showed “notconnect”; SW4 only port fa0/19-21 up as trunk with SW3, port f10/13-15, 16-18 showed “notconnect”;
SW1, SW2 and SW4 are: Switch>sh inv NAME: “Switch”, DESCR: “Cisco Catalyst 3550 24 10/100 baseT ports + 2 Gig uplink s fixed configuration Layer 2/3 Ethernet Switch” PID: WS-C3550-24 , VID: M0 , SN: CAT0826N4G4 …. System image file is “flash:c3550-ipservicesk9-mz.122-25.SEC2.bin”
SW4 is WS-C3750-24TS
Does it because 3550 have trunk limitation, or IOS problem?
Thanks.,
Josh
