I'm a little confused why my config doesn't work. Basically it's quite a simple setup.
I have a small network consisting of a 3750X with about 10clients. The clients are some PCs and some VoIP clients.
I want to separate the VoIP-clients from the PC-clients via VLANs. So, vlan999 is for the VoIP-clients, VLAN 1000 is for the data.
Further I want to have 1 admin machine that can administrate clients in both vlans. The admin machine is connected on Port 1/0/9. Now, if I want to access the switch from the admin machine, I can't get a connection. Ping is not working if the admin machine is set to a trunk with vlan 1000 and 999.
If a client is purely in vlan 999, I can ping the switch.
The admin client has the IP 192.168.0.102
Please have a look at my config because currently I'm lost. I deleted some line in the config below, but those interfaces have not been configured at all.

As you are connecting it to a Trunk port, the Network card in the machine needs to be capable of tagging 802.1q frames otherwise the switch will just tag every packet it receives with the native vlan ID which in this case would be Vlan1.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
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
