Application Centric Infrastructure (ACI) Engineer

Key Responsibilities:

• Lead or support migrations from traditional L2/L3 data center networks to Cisco ACI using an

  application-centric

  approach.
• Perform application dependency mapping and define ACI constructs such as

  tenants

  ,

  application profiles

  ,

  EPGs

  , and

  contracts

  .
• Translate existing firewall rules, VLANs, and routing policies into ACI policy models.
• Deploy, configure, and troubleshoot ACI components including

  APIC

  ,

  Nexus 9000 series switches

  ,

  leaf/spine fabrics

  , and

  fabric access policies

  .
• Collaborate with application teams to ensure accurate mapping of workloads and security policies.
• Integrate ACI with virtualization environments (e.g., VMware vCenter, ESXi).
• Monitor and troubleshoot ACI fabric issues, using tools like APIC GUI/CLI, SNMP, and Syslog.
• Conduct detailed cutover planning, testing, and rollback strategies for ACI migrations.
• Integrate ACI with virtual environments (VMware, Hyper-V), firewalls, and load balancers.
• Document technical designs, migration plans, and operational procedures.
• Train operations staff and provide post-migration support to ensure environment stability.

  application-centric migration

  in Cisco ACI.
• Demonstrated experience in

  application-centric ACI migrations

  , including dependency mapping and policy translation.
• Experience in analyzing existing network-centric environments, mapping applications to ACI constructs (tenants, EPGs, contracts), and executing migrations with minimal disruption.
