Validation Type

[ ] - Fault

[ x ] - Config

[ ] - Bug

What needs to be validated

1. Upgrading to 4.2(6d) and later or 5.1(1h) and later
2. EPG is a shared services provider (global pctag, provided global contract) and is part of a preferred group

Why it needs to be validated

Due to the behavior change contracts will no longer be pushed post-upgrade causing a significant datacenter outage.

The configuration will be faulted: e.g. F0467 Configuration failed for uni/tn-common/brc-shared/contract/epgCont-1/instp-ext-epg due to Invalid Contract Configuration, debug message: invalid-contract-config: Shared service provider cannot be in a Preferred Group.

Additional context

Documentation

"Due to CSCvm63145, an EPG in a Contract Preferred Group can consume a shared service contract, but cannot be a provider for a shared service contract with an L3Out EPG as consumer."

The configuration will be faulted starting in 4.2(6d)+ and 5.1(1h)+.
