service instance command is not as documented

[yoav.rothschild]

Hi,

I use Cisco 7609 with IOS 15.0(1)S1 and with ES+ module.

I try to configure a service instance, but the only possible commands I get are:

Router-1(config-if)#ser insta 22eth

Router-1(config-if-srv)#?

Ethernet EFP configuration commands:

  default   Set a command to its defaults

  ethernet  Configure ether lmi parameters

  exit      Exit from ETHER EFP configuration mode

  no        Negate a command or set its defaults

I need the "encapsulation ... " command.

Could someone explain what is the problem? ES+ module supports EVC-style configuration and Cisco official documentation claims that the above mentioned command IS supported.

Thanks,

Yoav.

Hello Yoav

Yes indeed it should be supported .. Is it possible to try different IOS if it is a lab router

NPE-1(config-if)#ser in 10 ethernet

NPE-1(config-if-srv)#?

Ethernet EFP configuration commands:

  default        Set a command to its defaults

  description    Service instance specific description

  encapsulation  Configure ethernet frame match criteria

  errdisable      Configure error disable

  ethernet        ethernet

  exit            Exit from ETHER EFP configuration mode

  group          Join a service group

  ip              Interface Internet Protocol config commands

  l2protocol      Configure l2 control protocol processing

  mac            Commands for MAC Address-based features

  no              Negate a command or set its defaults

  service-policy  Attach a policy-map to an EFP

  shutdown        Take the Service Instance out of Service

  snmp            Modify SNMP service instance parameters

  weight          Assign a weight to an EFP

NPE-1(config-if-srv)#

Hi,

I think I found the problem - we configured the port as switchport. Once the switchport removed I got all the possible commands for service-instance.

Do you know if switchport and service-instance are indeed mutual-exclusive?

Thanks,

Yoav.

Hi Yoav,

Seems so as as with EVC you may have L2/L3 services

But when you configure switchport you are only having L2

Example for L2/L3 services

interface GigabitEthernet1/1/1

service instance 100 ethernet

  encapsulation dot1q 10

  rewrite ingress tag pop 1 symmetric

  bridge-domain 100

service instance 200 ethernet

  encapsulation dot1q 20 second-dot1q 10-100

  rewrite ingress tag pop 1 symmetric

  bridge-domain 200

!

interface Vlan100

ip address 1.1.1.1 255.255.255.0

!

interface VLAN200

xconnect vfi VPLS

Hi,

Thanks a lot for the quick and informative answer.

One question though - can I attach a service instance to a VRF? Or must I do it like in your example with a VLAN interface? I wouldn't want to consume global-scope vlans for MPLS L3VPNs.

Thanks,

Yoav.

Hello Yoav

I didnt try it before but I believe you can configure VRF normally under SVI 100 but not under SVI 200
