We have a cisco 2950-12 switch that is owned and managed by our ISP. We were told that port 1 is VLAN520 and set to full/100.
We plug our own cisco 2950-48 switch from port 32 to that port 1 using a X-over cable.
I then proceeded to define an ip address for vlan520 on our switch:
ip address 172.17.193.12 255.255.255.0
ip default-gateway 172.17.193.1
and also set port 32 to vlan520 and full/100.
switchport access vlan520
Port 32 starts to blink amber and I can't ping anything.
But once I did a "no switchport mode vlan 520" on port 32, it starts to blink green and i can ping.
So is it safe to say that my ISP has misinformed me about port 1 on the 2950-12, ie, it should be vlan 1, not vlan 520?
