I see document for config VLAN between C2948G-L3 and C2900. I can work with C2950-24 and ping all VLAN. The port trunk not problem, but with C3548 is impossible. I tested with port-channel and subinterface, but not. The interface down/up, up/down all time after of config port with trunk.
The version IOS in C3548XL is 12.0(5.2)XU
Is possible work with VLAN between C2948G-L3 and C3548XL ?? in document is possible, but is not real.
