I find some problems below:
1) in 3550 i configure 8 vlan 10.12.82.0/27 ,and a 4 port 802.1q trunk, computer plug in 3550 working correctly. in order to communicate with some computer plug in 2924 , i config the right trunk group corresponding with 3550 , but the computers between 3550 and 2924 can communicate with each other , Is really nessary to set the interface port in 2924 to specified vlan
2) I want set the management to another vlan expect vlan 1, but the management vlan in 2924 must be vlan 1, Can i do that.
thanks
