Built-in tunnel interface on M7i

Hi all,

 

I'd like to sort out some things concerning built-in tunnel PIC on M7i.

 

  • Is this PIC build in on both FEB-M7i-M10i-S and FEB-M7i-SVCS-S ?
  • What does this PIC support? All the features of a separate real PE-TUNNEL or which some buts and ifs? How about its performance?
  • Does all this mean that on M7i we always have things like GRE, regardless we have any IP-services PIC?


Thank you.

Yes, it has a built-in tunnel pic, unless you also ordered the optional ASM module. I believe both card comes with built-in tunnel pic.

Note that the built-in tunnel-pic supports some 850M while the stand-alone TP is rated to 1 G. The m7i either has the default TP or the optional ASM in slot 1/1. In the latter case the ASM also provides the tunneling services. There is 1Gbs of capacity to the internal service pic slot, and it seems the ASM functions are capped to around 155 Mbps, which leaves some 845 Mbps for tunnel services. When  the ASM is plugged in (which is actually a full blown AS PIC without the casing), the tunnel chip is deactivated.

Yes for sure..


Thank you.
