General Mode isn't available in 3750 switch then how can configure it on interface any alternative way or mode same as General Mode to configure on 3750
You have to use "switchport mode trunk" where you can either allow all VLANs (default) or restrict the number of VLANs. If I remember right, on the 3750 you also need to set the trunk encapsulation to dot1q.
Actually i am upgrading my switch to 3750 from old one SG300 in which general mode is configured on some interfaces so I am just shifting same configuration to new one but error occurs for General mode
