WS-C3560G and 2600 router issues

Unanswered Question
Dec 14th, 2007

Ok I have a very basic setup that I can't get working.

Here is the setup:

Router 1 = 2600 series connected to the ISP

Switch 1 = Standard 1gig

Firewall 1/2 - Linux boxes

Lan switch 1 = 1gig managed

Switch 2 - Standard 1gig

Lan Switch 2 = WS-C3560G

router1 -> switch1 -> firewall 1 -> lan switch 1 (192.168.10.x)

..............................-> firewall 2 -> switch2 -> lan switch 2 (192.168.1.x)

The above configuration works, all packets are switch from lan 1/2 to the router. The problem is there should be no need to the switch 2 in this configuration. When I connect the firewall 2 directly to the WS-C3560G I can not ping either direction. I have eliminated all wires and everything up to the WS-C3560G, but only recently have I had access to the ios. The configuration of the port on the WS-C3560G is basically default.

What I need to do is diagnose the problem with this connection so that I can eliminate firewall 2 (by adding another nic in firewall 1) and switch 2 (hopefully by the help of you guys / gals).

So the end setup should look like this:

router1 -> switch1 -> firewall 1 -> lan switch 1

..................................................-> lan switch 2

Here is the WS-C3560G config: GigabitEthernet0/48 is the connection point

Current configuration : 9426 bytes

This is the first time I have touched this switch, but from from my understanding with now configuration at all it should work just like a none managed switch.

Any help or troubleshooting steps would be appreciate.

I have this problem too.

Check the Duplex and sped settings on the port. If autonegotiation doesn't try to manually change these values. Make sure you connect correct type of (Straight or Cross Through) cable between them. Check the encapsulation types on both the ends. If these doesn't work try upgrading the software.
