Hi All,

         I want to create a service instance without EFP (Ethernet Flow Point) is it possible to do that? I am using IOSvL2 switch in GNS3.

Any help regarding this will be great. Thanks in advance.

Hi,

If your using normal image on the GNS it will not work you have to have IOL image in order to enable L2 features,

Hello,

can you write out what you want to configure ? I am using:

Cisco IOS Software, vios_l2 Software (vios_l2-ADVENTERPRISEK9-M), Version 15.2(4.0.55)E

in GNS3, and at the very least it lets me configure service instances:

interface GigabitEthernet0/0
media-type rj45
negotiation auto
service instance 1101 ethernet
encapsulation dot1q 101
rewrite ingress tag pop 1 symmetric
bridge-domain 101

What exactly do you mean by 'service instance without EFP' ?

Hi,

    I am using Cisco IOSvL2 Switch in GNS3 and I have used image (vios_l2-adventerprisek9-m.03.2017.qcow2).

My topology is simple (Attaching Snapshot). I have configured 

On first Interface 

(config)# interface gigabitethernet0/0
(config-if)# switchport mode trunk
(config-if)# switchport trunk allowed vlan none
(config-if)# service instance 22 Ethernet [name]
(config-if-srv)# encapsulation dot1q 10
(config-if-srv)# bridge-domain 10

On Second Interface

(config)# interface gigabitethernet0/1
(config-if)# switchport mode trunk
(config-if)# switchport trunk allowed vlan none
(config-if)# service instance 22 Ethernet [name]
(config-if-srv)# encapsulation dot1q 10
(config-if-srv)# bridge-domain 10

So, Any other packet apart from VLAN ID 10 should not be forwarded. But that doesn't happen in my case, any other packet apart from 10 is forwarded.

Sorry, forgot to attach the snapshot.
