I have several devices that have different IP addresses and they could change as well. This is for a test/dev lab. However, we need to plug these devices into a switch and grant them internet access and that is it. Configuring a Catalyst 3750 switch ...

Replaced two old 3560's and a 2960 with a new Catalyst 3650-X and two 2960-X's. Routing seems OK for the most part, but there are some issues getting to the SAN VLAN.There is a trunk port between the core switch (3650) and the SAN switch (2960), and ...

NAT'ing external port 8080 to go to port 80 internally isn't working for me. Seems the auto/dynamic NAT statement for the server is working, and will just forward to port 80 when I try it, but not port 8080. Searched all over and it seems I have all ...

A Cisco 1900 series router provides DHCP for a LAN and interfaces to the internet. Adding a firewall to one of the ports on the 1900 to route some internet sides through an IPSec tunnel to be resolved on the other end, and want to keep traffic to tho...

Ended up resolving this with Cisco TAC. Thanks for suggestions. I was able to focus TAC to look at VLAN 2, and we found the 3650-X had the Layer 3 setup for VLAN 2, but not the Layer 2 setup. The clue was "show vlan" did not show it as a VLAN on the ...

Jon, there is something up with routing. 172.15.20.0 network is one example. Also pinging something on the 10.8.8.0/24 network, I get back random unreachable messages during pinging.Turning on verbose mode shows a public IP I don't immediately recogn...

John - saw your edit, and you're right. I actually test pinging 172.15.20.1 from one of the VLAN 2 access ports on the switch, assigning my laptop a 172.1520.x address. I can reach other IPs on that subnet oddly enough, but not the core switch.That i...

John - tried using 10.10.10.250 and still could not ping 172.15.20.1. It is the private subnet for the SAN, on VLAN 2. Not all of the switch ports are set to VLAN 2 on the SAN switch. There are some VLAN 1 ports, and then one Trunk port back to the C...

172.15.20.1 is the VLAN 2 IP on the core switch. Even with ip default gateway on the SAN switch pointing to the the core switch IP though doesn't allow a ping to it, which made me think something else might be missed..
