eNSP dot1q bug

Latest reply: Jun 30, 2018 09:55:44 2153 4 0 0 0
    Hi,
I try to test some topology on eNSP (ver. 1.2.00.510) and I found some problem with dot1q operation. I have simple topo:
                                                                         / PC1 (VLAN 10)
AR2200(Gi0/0/0) <----->(Gi0/0/1)S5700 <---                                                                       
                                                                         \ PC2 (VLAN 20)
There is some basic configuration on devices:
AR Router:
interface GigabitEthernet0/0/0.10
 dot1q termination vid 10
 ip address 10.10.10.1 255.255.255.0
#
interface GigabitEthernet0/0/0.20
 dot1q termination vid 20
 ip address 10.20.20.1 255.255.255.0
#
S5700
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 description To-PC1
 port link-type access
 port default vlan 10
#
interface GigabitEthernet0/0/3
 description To-PC2
 port link-type access
 port default vlan 20
#
PCs
PC1: IP 10.10.10.10/24 gw 10.10.10.1
PC2: IP 10.20.20.10/24 gw 10.20.20.1



Problem description:
I can ping both PCs from AR router. I can ping router interfaces (both VLAN subinterfaces) from PCs.
I can't ping PC1 from PC2 and vice versa.

Have you actually created the vlans on both the AR router and switch?

vlan batch 10 20

that's the command. The vlans are not created automatically when you add them to the interface.

Hello,

Yes of course I created VLAN on router and switch. I forgot to write this.

Maybe it is a eNSP bug, you can change some other device type to test
