ML-Ethernet Cards for the 15454

Answered Question
Dec 3rd, 2007

Hi

The ML series cards have two POS interfaces. Would you know whether it is possible to use POS sub-interfaces and map each one to a separate SDH circuit to create a hub and spoke network?

Cheers,

Phil

I have this problem too.

Hi Phil, no it's not possible. Unfortunately the ML series can have only two POS connections to SDH.

Since Rel. 8.5 there is a new ML-MR (ML Multirate Card) with 10 GigE Ports. But this card is only P2P for EPL services. Maybe this card could help you in your design. The card is very new and the SW feature set is very small at this time.

Cheers

Hi Rene - Thanks for the reply.

I don't think this will help with my design. The MR card also has 2 POS ports. I want to create a hub and spoke network - if the ML cards have only two POS interfaces and you can't map sub-interfaces to separate SDH-VCs then the hub node can only peer to 2 spokes.

Cheers,

Phil

Hi Phil

Ath the moment yes, but the ML-MR is designed to have more POS ports and also more than one RPR in future release. But another solution for a hub and spoke design is to use the CE-MR card. It gives you 10 GigE ports with 10 POS ports for P2P. You can use SNCP and/or LCAS as protection for the circuits instead of RPR.

Cheers
