Hi,
Redundancy in Fabric depends on mode at which SCBE3-MX cards are operating at , there are 2 modes [increased-bandwidth | redundant] and this is configurable
https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/redundancy-mode-redundant.html
- MX960 can have up to 3 SCB cards, in redundant mode 2 fabric cards are active and 1 card is standby , while in non-redundant mode / increased-bandwidth all 3 SCB cards are active.
- when all 3 SCB cards are active you get 1.5 Tbps fabric capacity per slot and when only 2 cards are active you get 1Tbps fabric capacity per slot and this is the default mode for SCB3-MX
If this solves your problem, please mark this post as "Accepted Solution."
