01

Local Administrator/User Password

cisco-mds-nexus / local-admin-password

Cisco MDS and Nexus NX-OS switches use local users for console, SSH, Telnet where enabled, NX-API, and management access. Initial setup requires creating or setting the admin password.

Notes

No universal Nexus/MDS admin password is modeled; platforms prompt for an admin password during first boot or setup.

03

AAA / SNMP Shared Secrets

cisco-mds-nexus / aaa-snmp-secrets

NX-OS configurations store RADIUS/TACACS+ shared keys, LDAP integration settings, SNMP communities/users, and local fallback credentials.
