Inter VLAN doesnt work on cisco7600

[Firuz Azimov]

Hi

I configure intervlan on cisco 7613 (2vlans on one port).

There are 2 vlans (vlan 10 and 20)

Users in vlan 10 cannot communicate with users in vlan20. 

I did successfully this configuration in many routers. But it doesn work in cisco7600 on ES+ card.

Maybe someone know how to resolve this issue.

Thanks.

Yeap! Two users connected to huawei switch.

show inter trunk output in cisco

May be you are correct problem may be between cisco and huawei. Unfortunately I dont have another cisco to test intervlan between two cisco.

Any idea how to correct configure trunk between cisco and huawei?

The same port configuration between cisco and huawei but in 1G port. Users can ping each other.

Some problems with tengig module

Any body heard about intervlan issue on cisco  7600-ES+2TG3C  card ?

[Firuz Azimov]

Also I noticed one thing.

When I ping from user in vlan 778 counts in show inter vlan 778 changed:

  L3 in Switched: ucast: 92 pkt, 9384 bytes - mcast: 0 pkt, 0 bytes mcast

92 packets 93, 94 and so on

Then I noticed thant counts in interface vlan 777 changing:

L3 out Switched: ucast: 1594 pkt, 117516 bytes mcast: 0 pkt, 0 bytes
Out direction its correct coz I pinging from user on vlan 778 to vlan 777.

But counts should changed when user on vlan 777 reply to user vlan 778

So in interface vlan 777 L3 in counts should be changed and out interface vlan 778.

But counts is not changing

I removed wccp on both interface vlan. The problem not resolved.

interface TenGigabitEthernet12/1
 description MAIN---CONNECT
 switchport
 switchport trunk allowed vlan 666,777
 switchport mode trunk
end

User on vlan 666 can ping interface vlan 666 ip address (gateway for user).

User on vlan 666 can ping interface vlan 777 ip address (gateway for another user)

User on vlan 666 can ping another users on another vlan (vlan connected to another physical port on cisco 7600)

User on vlan 666 cant ping user on vlan 777 (both vlans connected to port 12/1)

If vlan 666 connects to port 12/1 and vlan 777 connects to port 12/2 the can ping each other.

I dont understand why they cannot communicate. Maybe it cisco 7600 tengig limitations?

[Firuz Azimov]

Any ideas guys?

[Firuz Azimov]

ip routing is enabled because users on vlans can access internet. The problem only with communication between two vlans on the same port. Even users can access other vlans on another port. But if users in one trunk port they cannot communicate.
