CML VLAN interface not pingable

[lolypopkids]

Hi there

I've been using CML for a few months so I'm not an expert on it quite yet so maybe the solution is simple. I can't seem to be able to ping a VLAN interface.

Just as a simple demonstration, I hooked up two IOSvL2 switches together and gave them each an address in the 192.168.1.0/24 subnet on VLAN 1. I enabled ip routing globally on both devices but I cannot ping either switch. 

I know the switch is called IOSvL2, but I can ping using a routing protocol like EIGRP or OSPF. Just wondering if this is a bug or not.

Thanks

I do not see any bugs, ( i am using vIOS - (vios_l2-ADVENTERPRISEK9-M), Version 15.2) - works as expected.

how have you connected these 2 devices to each other?

post below information :

i do not see any issue with config, save config, reload both the switches and test.

[lolypopkids]

I appreciate the suggestion, unfortunately I tried that numerous times to no avail.

I'm guessing this is a weird bug that is occurring, but I'm not sure how to fix it.

It looks like my show version is slightly different, but I don't know if that's important or not.

Your is latest than mine, i wil wipe the node and re-create a Lab and test it..

some time virtual give lot problems. but your config is very simple to work as expoected.

[lolypopkids]

I appreciate the help

I'm wondering if I have to rebuild the whole server and start from scratch. That is something I don't really want to do, but if I have no choice then I have no choice.

[balaji.bandi]

i am not suggesting to rebuild, delete the nodes and re-create the lab and test it.

[lolypopkids]

Unfortunately I tried that several times. Still can't do a simple ping unless I have a routing protocol enabled.

[lolypopkids]

I rebuilt the lab and still the same results. I took two routers and put the same config on them and they ping just fine. I then moved the cable to connect one switch to one router and the ping actually responded using the same configuration.

i'm a bit late on that but i ran into the same today. when you take a look on the SVI mac-address, you'll see that SW1 and SW2 has the same after changing one switch to another MAC it was working: See https://developer.cisco.com/docs/modeling-labs/#!cml-release-notes/bug-fixes

bug description: Port-channels do not come up in IOSvL2 nodes. (also applies to SVIs).

Hope that helps
