Thank you for your help.

Hi,

your configuration is valid for the most parts. Your issue is the tagging configuration between the both switches. The Cisco side is untagged because of the "switchport mode access vlan 99", while the VSP side is tagged by default. To change the tagging behavior of the port you have to enter the interface and change it for example:
interface gigabitEthernet 1/1
no encapsulation dot1q
exit

The "no encapsulation dot1q" command is basically telling the port, that it´s not tagged anymore. For troubleshooting purpose you should stick to classic mac-address-table of the VSP Switch, which you can see with "show vlan mac-address-entry port 1/1". Here you will see no mac-address as long as the port is tagged.

Best regards,

Phil

Dear Phi,

Sorry for late reply. Currently, I can ping to IP 192.168.99.88, I assume that this configuration is coexistence setup. There are more issues as below

a. I can ping another IP with context "grt" but "mgmt"

b. I can't access web service although enable it

c. Why ARP entry in MGT Instance show failed?

Thank for your help

To me it looks like a problem with the virtual image. Can you show me the output of "show sys-info"? Also can you please provide the whole configuration?

Hi Phil_,

I give up to manage Switch by interface vlan. Now I am using OOB management. It's ok now, I can manage this switch by this way, but there are more a lot of issue, such as DHCP reply not work, ICMP ping through this Switch to another device can not be successful even they are in the same vlan. I am thinking about switch them to GNS-Lab.

You can try but I don´t know honestly if this will work. Unfortunately there is no focus towards the virtual images of voss from extreme.
