My answers above AFAIK
1. Does Juniper EX8200 support virtual chassis?
- No, this is planned and we are all waiting for this
2. Can i dual home an edge switch to two EX8200 core switches (without using STP) using something similar to SMLT on found on nortel?
- No, the answer from juniper is to use RTG (Redundant trunk group) instead (port backup or link backup on others vendors, Flexlink on C..)
3. If i am teaming nics on server to two EX8200 core switch, is there any special configuration required on the core.
- You can't make an aggregation (ie LACP) on two different Chassis
4. Does Juniper EX8200 support Multi Chassis LAG?
No.
Yes we are all waiting for this
The answer today on Juniper switches is 4200 boxes but not the chassis
Hope this will help you
