Restrictions of the Cisco ASR 9000 Series nV Edge System
These are some of the restrictions for the Cisco ASR 9000 nV Edge system:
+ The first generation Cisco ASR 9000 Ethernet linecards are not supported.
+ Chassis types that are not similar cannot be connected to form an nV edge system.
+ SFP-GE-S= is the only Cisco supported SFP that is allowed for all inter rack connections.
+ TenGigE SFPs are not supported on EOBC ports.
+ The nV Edge control plane links have to be direct physical connections and no network or intermediate routing or switching devices are allowed in between.
+ The nV Edge system does not support mixed speed links.
+ The nV Edge system does not support the ISM or CGN blade.
. RSP440
. Typhoon Line Card. Trident Line Card or RSP 3G cannot co-exist in the same system
. Requires a cluster software license on each chassis
. 4.2.1 image or above required
. Only like-like chassis supported in 4.2.1. Mixed Chassis Support no yet committed
. Single RSP per chassis is supported but not recommended due to lack of fabric redundancy on the physical chassis.
