I think I'll add the allow line, just to see what happens. Joe Heaton From: Eldridge, Dave [mailto:[EMAIL PROTECTED] Sent: Saturday, February 09, 2008 11:10 AM To: NT System Admin Issues Subject: RE: Help with HP/Cisco switch communication Yes there are sort of. Hp calls them tagged ports what Cisco calls trunks. I believe the port connected from the cisco to the hp has to be trunked on the cisco side if you are passing more than one vlan. interface gigabit 1/0/1 or whatever port you are using. switchport trunk allow vlan 20,39,68 etc... whatever vlans you are trying to pass. switchport mode trunk I just did this between two hp 2848's and a cisco 6509. hope this helps ________________________________ From: Joe Heaton [mailto:[EMAIL PROTECTED] Sent: Saturday, February 09, 2008 11:42 AM To: NT System Admin Issues Subject: RE: Help with HP/Cisco switch communication Yes VLANS are involved. We've got the Cisco set to accept/allow all VLAN traffic, and the HP port is tagged in all VLANS that I want it to work with. There are no HP "trunks" involved.

Is the port you're plugging the HP into trunked? On Feb 9, 2008 10:26 AM, Joe Heaton <[EMAIL PROTECTED]> wrote: Don't know if anyone is out there today, but if you are, I could really use some help. I've got a brand new Cisco 3560 layer 3 switch that I am using to replace a Cisco 2651 router. I have, with the help of Aaron Rohyans, configured the 3560 to emulate the operation of the 2651. Unfortunately, when I plug the 3560 into the HP 4108 switch, there is no communication between the two. The HP never detects the MAC address of the Cisco, and I cannot ping to it from the other side, either, which is plugged into my firewall. The Cisco is not talking to anyone. I have the configs of both the router and the 3560 if anyone would like to see them, and if anyone has any advice, I'd really appreciate it. I'm also sitting at my desk, if you'd like to give me a holler...
