eNSP dot1q bug

Latest reply: Jun 30, 2018 09:55:44 2153 4 0 0 0
I try to test some topology on eNSP (ver. 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
interface GigabitEthernet0/0/0.20
 dot1q termination vid 20
 ip address
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
PC1: IP gw
PC2: IP gw

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.

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