At my Cisco 3750 switch I have 2 vlans...vlan1 and vlan 100. In both vlans the switch has an IP-addresses..
I can succesfully Telnet to the vlan100's ip-address.
Trouble exists if I try Telnel to the vlan1 ip-address.
Sure, I use a router for intervlan routing. But no one ACLs exist on a router.
Is there any hidden rules at 3750 that prevent Telnet to the Switch from NON-NATIVE vlans??
If you do not change the login local or configure a user ID and password, then I do not see how telnet will work to this switch.
And another aspect of the issue became apparent when I reviewed the configuration. The switch config does not enable ip routing. This means that the switch is operating as a layer 2 switch. And one characteristic of layer 2 switches is that they have only a single active VLAN interface. Try enabling ip routing on the switch and see if it changes the symptom of telnet to the switch VLAN 1 interface.
