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

HI,

So first make sure your vlans are up do sh vlan and make sure 200 is up.

Second you may want to remove duplex auto and hard code that. duplex full
 do sh cdp neigh make sure the devices see each other.  I assume you pinging from one device to the other.

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

Can you do sh vlan?

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.

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
