Hi

 You need to enter the command "ip routing" on the switch.

[vtuaan dinh]

Hi

Im already entered that. You can see ip routing in my config

[Flavio Miranda]

Sorry, missed that. And you also have  licensing "license boot level ipbasek9"

should work.

Can you ping from the switch to the hosts?

[vtuaan dinh]

Yes i can ping from switch to both hosts in 2 different vlan.

[Flavio Miranda]

 Then, or you facing a Bug or something similar.  I´d recommend factory reset it and upgrade, if possible.

[vtuaan dinh]

I try to factory reset by CLI

#delete flash:vlan.dat

#erase startup-config

and config again but still can't fix it

[David Ruess]

Hello,

Do you have hosts connected to the interfaces you have access vlans on? Are you pinging from a host one 1 vlan to a host in another vlan?

If so do the hosts have the correct ip and default gateway/mask?

Does the ping say failed or unreachable?

-David

[vtuaan dinh]

Yes i ping from 1 host vlan 50 to another host in vlan 60

The host is correct ip and subnet mask

Ping say request time out.

I have a server leased DHCP in ip 192.168.1.1(vlan 1). Host in vlan 50 still receive DHCP but can't ping to the server

[David Ruess]

Does the DHCP server/pool only give out vlan 1 IP subnet addresses? What’s the address of the VLAN 50 host? Can it ping it’s default gateway of 192.168.50.1?

[vtuaan dinh]

My DHCP server give ip for 5 vlan. Host in vlan 50 have ip 192.168.50.10, that host can be ping to all of default gateway in switch. Even the host can access router in ip 10.0.0.1 but can't ping host in other vlan 

I try to reset factory but still can't resolve problem

[David Ruess]

Ok that host can ping all default gateways. Check a host in each vlan. Can all of them ping their respective gateways?

can you provide the PC configuration of 2 PCs that can’t ping each other in different vlans?

[vtuaan dinh]

PC1 in vlan 50, IP: 192.168.50.10 connect to interface GigabitEthernet1/0/4. PC1 can ping all default gateways.

PC2 in vlan 60, IP: 192.168.60.10 connect to interface GigabitEthernet1/0/6. PC2 can ping all default gateways.

But 2 PC can't ping each other

[Jon Marshall]

Check PCs for firewalls.

Jon

[vtuaan dinh]

No, i sure problem in the switch. Because when i bring 2 pc to another network, it can ping normally
