We have configured a 2960G-24TC-L (Lan Based) switch up with IP address/default gateway (VLan 9) etc and it appears in our network and any device we connect to it has network access but we cannot communicate with it.
We use Cisco 2960s IP Based switches in our network here. With these switches we can manage them via Cisco Network Assistant and Telnet which the LAN based switch does not seem to give. Do you know of any way around this? Is it a configuration issue? Any help you could give would be most appreciated. I have attached a copy of the switch config.
Looking at your config I think interface GigabitEthernet0/20 is the uplink to your Core/Distribution layer device. If this is the full config of your switch than users connecting to any of the ports will be a part of Vlan 1 which is passed over the trunk by default and hence the PC's connecting to this switch are able to communicate with the outside network. If you see the trunk configuration there are no other Vlans passed and hence the Vlan 9 management interface could not be reached.
Add the command "switchport trunk allowed vlan add 9" under interface Gig 0/20.
He should not have to add vlan 9 under interface 20 because the the statement switchport mode trunk indicates all vlans are allowed by default. you may want to check the opposite end and make sure vlan 9 is allowed across the trunk.
Thank you guys for your very helpful posts. The issue was an oversight on my behalf which you have all picked up on. I never added the Vlan information to the switch configuration. When I did add them, we were able to communicate with the switch via Vlan 9. Thank you again for all your help.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
