Este documento descreve como configurar a N_Port ID Virtualization (NPIV) ou N_Port Virtualization (NPV) com Fibre Channel over Ethernet (FCoE) entre o Cisco Unified Computing System (UCS) e um switch Nexus 5000.
As informações neste documento são baseadas nestas versões de software e hardware:
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Figura 1. Topologia usada na configuração
Há dois procedimentos descritos aqui para ajudá-lo a configurar o UCS:
É importante observar que o UCS não suporta um FC-Map não padrão quando no modo NPV. Para obter mais informações, consulte os IDs de bug CSCuJ62005 e CSCud78290 da Cisco:
Criar VSANs FCoE
Você precisa criar VSANs e VLANs FCoE no UCS para transportar o tráfego FCoE. Uma prática recomendada, mas não obrigatória, é alinhar o ID da VSAN com o ID da VLAN FCoE para ajudar a rastrear e solucionar problemas.
Nome | Insira um nome para a VSAN |
Zoneamento FC | Desabilitado - Isso é usado somente quando você implementa os recursos de zoneamento local |
Botões de rádio de estrutura | Escolha a estrutura A |
ID da VSAN | Insira a ID da VSAN para a VSAN criada na estrutura A - Isso deve corresponder à ID da VSAN que será criada no Nexus 5000-A |
VLAN FCoE | Insira a ID da VLAN FCoE para a VLAN que mapeia para esta VSAN - Isso deve corresponder à ID da VLAN que será criada no Nexus 5000-A |
Nome | Insira um nome para a VSAN |
Zoneamento FC | Desabilitado - Isso é usado somente quando você implementa os recursos de zoneamento local |
Botões de rádio de estrutura | Escolha a estrutura B |
ID da VSAN | Insira a ID da VSAN para a VSAN criada na estrutura B - Isso deve corresponder à ID da VSAN que será criada no Nexus 5000-B |
VLAN FCoE | Insira a ID da VLAN FCoE para a VLAN que mapeia para esta VSAN - Isso deve corresponder à ID da VLAN que será criada no Nexus 5000-B |
Configurar o canal de porta UCS FCoE
Há vários procedimentos necessários para configurar o Nexus 5000 para FCoE e NPIV:
Habilitar recurso FCoE
Nexus 5000-A# configure terminal
Nexus 5000-A(config)# feature fcoe
FC license checked out successfully
fc_plugin extracted successfully
FC plugin loaded successfully
FCoE manager enabled successfully
FC enabled on all modules successfully
Enabled FCoE QoS policies successfully

Habilitar NPIV no Nexus 5000
Nexus 5000-A# configuration terminal
Nexus 5000-A(config)# feature npiv
Nexus 5000-A# show npiv status
NPIV is enabled
Habilitar LACP no Nexus 5000

Configurar parâmetros de QoS do Nexus 5000 FCoE
Os recursos configuráveis de QoS do Cisco NX-OS permitem classificar o tráfego de rede, priorizar o fluxo de tráfego e evitar congestionamento. A configuração de QoS padrão no Nexus 5000 fornece serviço sem perdas para tráfego FC e FCoE e serviço de melhor esforço para tráfego Ethernet. Os parâmetros de QoS do Nexus 5000 FCoE já devem ser configurados por padrão.
Nexus 5000-A# show startup-config ipqos

Criar VLANs Nexus 5000
Crie duas VLANs para uso de FCoE. O par deve se correlacionar com FI-A e o ímpar deve se correlacionar com FI-B. Use as IDs de VLAN FCoE especificadas na seção Configurar o UCS deste documento.
