VSS Etherchannel Issue ?

[mr.marslin]

Dear Sir,

Follow the attach file.

Now, I want to run VSS function, but the edge switch two uplink across two ISP link!

Could I setup the etherchannel:

1) VSS & Edge Switch Etherchannel mode ON.

2) Etherchannel load-balance mode:

    VSS --> dat-ip-mac
    Edge Switch --> scr-ip-mac.

Have any issue about this plan ???

Thanks.

I do not believe you can create a Multi-chassis EtherChannel with the edge switch to the ISP switches. MEC requires two physical switches to appear as one switch, such as in a VSS.
