How to configure access between Vlan on С3750G?

Question

Cisco

Good day experts. Perhaps I will seem headless and crooked, but I have already been brought to a state of despair.
I have 3 C3750G catalysts connected in a stack. The firmware is the latest 15th service. I have a network for 100 machines, it needs to be divided into 3 vlans. I made the whole scheme in a tracer package, it works ... Vlan machines see each other, pings run. Accordingly, all this after #ip routing.
I took my real stack, hacked 2 machines into it, they are respectively in native Vlan1.
Telnet, Create 2 Vlan:
Switch(config)#vlan 50
Switch(config-vlan)#name 50
Switch(config-vlan)#exit
Switch(config)#vlan 40
Switch(config-vlan)#name 40
Switch(config- vlan)#exit
Next, I assign network settings to the machines:
1. 192.168.50.2
255.255.255.0
192.168.50.1
I hang on port Gi1/0/8
On C3750 I work out the code:
Switch(config)#int Fa0/8
Switch(config-if)#switchport mode access
Switch(config-if)# switchport access vlan 40 Switch(config -
if)#no shut Switch (
config-if)#exit
2. 192.168.40.2
255.255.255.0
192.168.40.1 if)#switchport mode access Switch(config-if)#switchport access vlan 50 Switch(config-if)#no shut Switch(config-if)#exit Assign addresses to SVI interfaces: Switch(config)#int vlan50 Switch(config -if)#
%LINK-5-CHANGED: Interface Vlan50, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan50, changed state to up
Switch(config-if)#ip address 192.168.50.1 255.255.255.0
Switch(config- if)#no shut
Switch(config-if)#exit
Switch(config)#int vlan40
Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan40, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan40, changed state to up
Switch(config-if)#ip address 192.168.40.1 255.255.255.0
Switch(config-if)#no shut
Switch(config-if)#exit
Switch(config)#ip routing
Switch(config )#exit
Routing between VLANs on the L3 switch
With this setup and configuration in the packet tracer, both machines see and ping each other.
With the same configuration on a real C3750, each host in the wealan pings the SVI of its own (as the main gateway) and the neighboring wean, but the host in the neighboring wean does not ping. Those. it seems like routing works, but somehow not completely. My ultimate goal is to have several Wealans to enable individual computers and different subnets to see each other. Unfortunately, I won’t be able to get away from this, because. my flat network is already firmly rooted, which is harder to break than to make routing rules. A little lower I will give the config. I compacted it as much as I could, reducing only the number of unused ports.
Guru, I ask for your help in advice, what did I do wrong or did not do? I tried to create ACL rules, hung them up as you like in different variations for 4 possible options (both on both ports and on both SVIs)... Looks like I'm being really stupid. Please help.

Answer 1

How to:

interface GigabitEthernet1/0/7
no switchport
no ip address
!
interface GigabitEthernet1/0/8
no switchport
no ip address
!

And it should be like this:

vlan 50
 name 50
!
vlan 40
 name 40
!
interface GigabitEthernet1/0/7
 switchport mode access
 switchport access vlan 50
!
interface GigabitEthernet1/0/8
 switchport mode access
 switchport access vlan 40
!
