Unable to ping PowerConnect 3324
Hi,
I had configured PowerConnect 3324 to allow VLAN 2 (data only). IP address is set for VLAN 2 interface. All switchports by-default have mode acces to VLAN 1. The fact is I cannot even ping this IP address from network, and of course telnet and management thru web are failed. But all client connected to this switch are able to grab VLAN 2 dynamic IP.
Moving forward, I changed uplink switchport access to VLAN 2, leaving others to VLAN 1. I was able to ping the mentioned IP, but clients couldn't get dynamic IP. At the end, only by changed all switchport access to VLAN 2 resolved this issue. Is this the way 3324 works?
Another question is physically 3324 has 24 ethernet ports plus 2 gig ports, but using sh run command, it displayed 48 ethernet ports. Why?
Regards,
Aliozo

This perfectly describes how an access mode port operates. Since all the client systems were in access mode, they could ONLY communicate to VLAN 1. You would need a layer-3 device configured to route between VLAN 1 and VLAN 2 in order to have the clients communicate in that way.
The only ways that a port can communicate with multiple VLANs is either via trunk mode (provided the connecting device understands VLANs and supports 802.1Q frame tagging), or via port overlapping in general mode(a means of having multiple VLAN-unaware systems participate in separate VLANs for security purposes, while still having access to a single shared resource). This is the way VLANs work, not just on the PowerConnect 3324.
In your case, you'd likely want the uplink port on the switch to be trunk mode, and passing traffic for both VLAN 1 and VLAN 2 (again, as above, the other side of the uplink *MUST* be a VLAN aware device).
As for the port enumeration in the CLI, this is by design. The 3324 and 3348 both use the same software. Since both switches are also stackable with one another, they have to be able to recognize and manage a switch that could potentially have more ports than the root switch physically has.
