Enable STM-1 on a CISCO7606-S SPA-1XOC3-ATM-V2

[Luis Salazar]

Hi everyone I need your help on this, I have this problem, I need to enable STM-1 on this sub-module: 1xOC3 ATM SPA, more specific:

Mod Ports Card Type                                                  Model              Serial No.

2         0       4-subslot SPA Interface Processor-400  7600-SIP-400       SAL1706YTSW

Mod  Sub-Module                  Model                             Serial       Hw     Status

---- --------------------------- ------------------ ----------- ------- -------

2/0 1xOC3 ATM SPA        SPA-1XOC3-ATM-V2   SP61703X6E6  1.80   Ok

I've always configured this type of module without any problem: SPA-1CHOC3-CE-ATM, for example like this:

******************************************************

acr 3 type CH-OC3

!

controller SONET-ACR 3

no shutdown

framing sdh

aug mapping au-4

!

au-4 1 tug-3 1

  mode c-12

au-4 1 tug-3 2

  mode c-12

au-4 1 tug-3 3

  mode c-12

!

controller SONET 4/2/0

no shutdown

au-4 1 tug-3 1

  mode c-12

au-4 1 tug-3 2

  mode c-12

au-4 1 tug-3 3

  mode c-12

!

aps group acr 3

aps working 1

!

controller SONET 3/2/0

no shutdown

framing sdh

clock source line

aug mapping au-4

!

au-4 1 tug-3 1

  mode c-12

au-4 1 tug-3 2

  mode c-12

au-4 1 tug-3 3

  mode c-12

!

aps group acr 3

aps unidirectional

aps protect 1 x.y.z.w

!

interface CEM-ACR3

no ip address

!

network-clock select 2 controller SONET 3/2/0

network-clock select 3 controller SONET 4/2/0

************************************************************

But my problem is, now when i want to configure this other type of module SPA-1XOC3-ATM-V2, the above configuration doesn't work. I want to know if I should make any changes in my usual configuration due to the type of card.

Thanks for your comments and replies..

Hello Luis,

the new interface is not channelized as the previous one

this is the main difference.

see

http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76cfgatm.html#wp1433854

Router(config-if)#

atm framing  {sdh|sonet} 

Hope to help

Thank you Giuseppe for your reply, are you saying that the only problem with my previous configuration is this:

I should configure the framing with this command "atm framing sdh" instead of "framing sdh".. like this?

controller SONET-ACR 3

atm framing sdh

controller SONET 4/2/0

atm framing sdh

controller SONET 3/2/0

atm framing sdh

I'm going to tested to see if it works now..

On the other hand something that I'm not sure, it's about this command "acr 3 type CH-OC3", I used it for this SPA-1CHOC3-CE-ATM.. Should I have to change it for this module: SPA-1XOC3-ATM-V2 ?

Thanks!

Hello Luis,

you configure the command under

interface atm x/y/z

as explained in the link I have provided.

The other commands that you are mentioning are relative to APS circuit protection and I'm not sure they can be applied to this new hardware.

Review the configuration guide I have provided before.and check for the the APS examples

Hope to help
