SW 1: vlan 1111 with SVI: 192.168.1.1/24 . The said vlan is passed on trunk between SW1 and SW 2.
SW 2: SVI for vlan 1111 and vlan 1117 with no ip address assigned. G0/2 is an access port in vlan 1111
, G0/3 is in access port vlan 1117. there is default gateway which point on 192.168.1.2.
SW 3: It run trunk between SW 3 and SW 2 and vlan 1117 is allowed on it. VLan 1117 SVI is
192.168.1.3/24
Q) I am unable to ping from SW 1 to SW 2. It is the same setup whihc is up and running in production
but instead of loop cables, we have packet shaper as an inline device. Can anyone help in establishing
IP connectivity between SE and SW 3.

In your diagram sw2 does not have any IP address assigned to it. If that is the case you can't ping from sw1 to sw1.
Also, is vlan 1111 and 1117 in the same subnet?

Hi Reza,
SW 2 do not need an IP address, they have a SVI but no IP address configured for them . . Yes, vlan 1111 and vlan 1117 are ins same subnet ? i do not think ip address configuration will fix the issue
SW 2
int vlan 1111
no ip address
int vlan 1117
no ip address

An SVI with no IP address is useless. SVI is a layer-3 interface and so in order to ping sw2 it needs an IP.

It doesn't work even with IP address . SVI with no ip address work like charm, it is already working in production. Design provided is exactly the same but instead of loop cables, we have packet shapers .

In Your original post You say it's not possible to ping between sw1 and sw2, and that's because You haven't an ip address configured.
You also state You want to have connectivity between SE and sw3, I can't see any SE in the drawing.
I suppose it's between SW1 and SW3 You meant. How about spanning-tree, is all ports in forwarding state? Sometimes the ports get into inconsistent state when vlan are tied together.
