[c-nsp] IP issues with 3560

[Sophan Pheng]

Still having issues, although I tried to follow your suggestions. Here is my config, can you tell me if im heading in the right direction? I think im confused on the SVI portion, each time I try to set an IP to the port interface, it tells me it overlaps with the vlan IP.

Current configuration : 1342 bytes

I have a server sitting at 10.125.25.5/255.255.0.0 that connects to the rest of the network via a microwave link. It connects to the 10.125.19.x segment to upload data to an archiving server. I need to be able to ping 25.2 from 19.x and vice versa.


Please double check your subnet mask.  255.255.0.0 would place both
10.125.25.5 and 10.125.19.x in the same subnet.  If you separated the
hosts on different VLANs, then the switch, even if configured for
routing, would not route such packets.

Also check your SVI interfaces on the switch.  Each VLAN should have
its own SVI interface with an IP in the corresponding segment. From
there, ensure IP routing is enabled and the switch should then route
packets from one VLAN to the other.

Good Luck.
