Need help configuring layer 3 between S4810 and PC6248

I'm trying to get traffic to route through an S4810 and PC6248 to allow communication between 1GB and 10GE devices.

The S4810's are connected to the 10GE uplink modules in the rear of the PC6248's. 

S4810 Config:

TE 0/0 0/1 configured into Port-Channel 1 -> connect to PC6248 uplink module

VLAN 100 - Port-Channel 1 tagged

IP address on int VLAN 100 - 10.100.100.1/24

 

PC6248 Config:

1/xg3 1/xg4 configured into Channel-Group 1 - trunk allowing VLAN 100

IP address on int VLAN 100 - 10.100.100.2/24

VLAN 100 IP routing enabled

 

Any device directly connected to S4810 can ping 10.100.100.1, and any device directly connected to PC6248 can ping 10.100.100.1.  But you can ping across the 2 switches.

Any ideas/suggestions?

I believe this working now by removing the LACP and IP address for VLAN 100 on the S4810.  Will still welcome any comments/suggestions; thanks.

Your LAG on the 6248 is a static LAG, while the S4810 is LACP. So it was a good move making the configs match each other, both LACP or both static.

With the 6248 setup to do the routing, make sure that the clients accessing VLAN 100 have a default gateway of 10.100.100.2.

Your devices connecting to the PowerConnect will need to be in access mode for VLAN 100.

console(config)# interface ethernet 1/e1

console(config-if)# switchport mode access

console(config-if)# switchport access vlan 100

Other than that things look ok to me, and it sounds like your on the right path.
