Dear cisco!

We have 2 switch 3750: WS-C3750-24PS-S and WS-C3750G-48PS-S

We using stack cable to connect 2 switch above, then WS-C3750-24PS-S plays role master and WS-C3750G-48PS-S plays role slave.

So we config FE 1/0/9 and FE 1/010 on WS-C3750-24PS-S n stack mode) and Ge 2/0/9 ; GE 2/0/10 on switch WS-C3750G-48PS-S n stack) is membes ò VLAN 26. so Gi3/0/1 on WS-C3750-24PS-S is trunk mode.

But only pcs plug in port FE then get IP from DHCP server and connect Internet;  Pcs plug in port GE cann't get ip and cann't connect Internet.

Swithc 3750 have IOS: c3750-ipbase-mz.122-25.SEB4.bin

Could you please help us solve this problem?

Maybe the clients connected to the second switch are in the wrong VLANs or PortFast isn't enabled?

Issue a "show stack" command and show us what you get.

Do a "show run int f1/0/9, f1/0/10, g2/0/9, g2/0/10" and show us what you get
