Configuring the OmniSwitch OS6900/OS10K for FIP-Snooping.

Multi-Hop FCOE Deployment

1.2 Configuring the OmniSwitch OS6900/OS10K for FIP-Snooping.

Please refer to the earlier post for steps to configure the NPIV Gateway. Once that is complete, the following should be configured in order to allow initiators connected to edge Switches to login to the Fibre-Channel Fabric.

a) Configure FCOE vlan and FIP-Snooping on Core and Edge Switches .
b) Configure port roles for Security ( Please refer to T11 FC-BB-5 documents)

c) Create a Lossless Fabric (PFC)& Bandwidth guarantees for Storage & TCP traffic( ETS)
d) Enable DataCenter Bridging Exchange Protocol and Application TLV’s to auto-configure the Converged Network adaptors on the Servers.

While configuration notes for the the first two items are shown  below, Creating a Lossless Infrastructure using DataCenter bridging protocols warrants a seperate post by itself.

Sample Configuration on DC-EDGE-104
====================================
fcoe fip-snooping admin-state enable
fcoe vlan 252 admin-state enable
fcoe vlan 252 name “FCoE VLAN”

fcoe port 1/1/18 role edge [Configure Port connected to Server as an Edge Port. This enables dynamic ACL’s which configures a level of security to the Initiator-Target communication ]
fcoe linkagg 22-23 role mixed [ Core Facing Ports can be either configured as Mixed/Trusted/FCF-Only/E-Node only based on the location in the network relative to the FCF or the Enodes]
vlan 252 members port 1/1/18 tagged [Tag both edge and network facing ports with the fcoe vlan]
vlan 252 members linkagg 22-23 tagged

Sample Configuration on Core-Switches DC-CORE-01 & DC-CORE-02
==============================================================

fcoe vlan 252 admin-state enable
fcoe vlan 252 name “FCoE VLAN”
vlan 252 members linkagg 21 tagged
vlan 252 members linkagg 23 tagged
spantree vlan 252 admin-state enable
spantree vlan 252 priority 4096  [ By manually configuring STP priority, the topolocy change becomes deterministic upon root-bridge failures ; ensure Backup root bridge has second highest priority]

fcoe fip-snooping admin-state enable
fcoe linkagg 21 role mixed
fcoe linkagg 23 role mixed
