Summary

User may face network reachability issue if OOB Management is not specified in separate VRF when connected on the same infra as production VLANs. For instance, if OOB is used as VLT Backup link and connected to a dedicated VLAN, it may show as status "down."

 

Products Affected

This is not a hardware platforms-specific issue.
OS: 10.4.0.x

 

Root Cause Analysis

Management interface must be set in a dedicated management VRF.

Example of Non-working configuration:

Interface mgmt1/1/1 Configuring Out of Band Interface
No shutdown Enabling interface
IP address 10.1.1.1/27 Setting IPv4 address
IPv6 address autoconfig Enabling IPv6 automatic addressing
VLT-domain 43 Creating a VLT domain
Backup destination 10.1.1.2 Setting VLT backup heartbeat to remote OOB IP
Discovery-interface ethernet1/1/25-1/1/26 Set VLTi link

 

Software Fix

None: Working as designed

 

Workaround Solution

There is a documented configuration procedure in the Release Notes - Section Management VRF.
