Unable to Ping Cisco SVI's

Hello Experts,

Can someone please tell me what I'm missing here. I have switches connected via eth 1/0, and an SVI's for vlan 200. I have configured svi's 200.1.1.1 255.255.255.252 and 200.1.1.2 255.255.255.252 for DLS2 and ALS2 respectively, however I can't ping from als2 to dls2 and vica versa.

Can someone shed some light on the issue.

Attached are the configs

Cheers

Carlton

In the attached files I showed that vlans were up.

I will change duplex settings but I seriously don't think the issue is with duplex

As you can see both routers can see each other via cdp....

Don't understand why als2 can't ping 200.1.1.2 and dls2 can't ping 200.1.1.1

DimaExpert33

Hi
Just want to make sure we talking about the same thing I see that interface vlan 200 is up how about the vlan itself. Can you ping it self?
from DLS2 200.1.1.2

cpatte7372

ASKER

Hi,

Yeah from DLS2 I can ping itself on 200.1.1.1

DimaExpert33

how about on the other side?
als2

and your last statment Yeah from DLS2 I can ping itself on 200.1.1.1?? IS this right or is it suppose to be 200.1.1.2?

Can you do sh vlan?

Are you doing this in virtual lab?

Dima,

Yes, this is a virtual lab....

if this virtual make sure to hard code duplex and speed.
on the link

and try to use 255.255.255.0 maks do shut no shut and see if it works do it on both interfaces

cpatte7372

ASKER

Dima,

It would appear configuring static access between two switches isn't supported on IOU (IOS on Unix) . I configured the links as trunks and it worked fine.

DimaExpert33

ok problem solved virtual labs are not 100% same as real equipment.
Yes trunk definitely an option. if you just want vlan 200 on the trunk do sw trunk vlan 200, this will allow only that vlan.
Please mark this complete
