This Solution intends to provide a zero touch configuration in a DC Network, and allows an AOS switch to act as a plug and play data center bridge.
In Data Center (DC) bridging, deployment currently requires more user interventions to configure Fibre-Channel Over Ethernet (FCoE) bridging or interworking of FCoE and Fibre-Channel (FC) networks. When a new bridge is deployed, administrator has to manually configure the pre-requisites to accept FC/FCoE frames and to establish sessions. This manual configuration when introducing new DC Top of the Rack (TOR) or DC Switches that have the capability to communicate to the FC as well as FCoE devices, takes time and is also prone to human errors.
An Administrator has to configure the Port roles, VLAN and VSAN for the FCoE and FC network equipments, at the time of introducing a new DC Network element into the network. The proposed solution allows the new DC Network Element to Learn the Port Roles like Fibre Channel (NPIV,R-NPIV,E-Tunnel) or FCoE (Enode connected port, FCF Port, VE port), Fibre Channel VLAN through snooping the incoming packets and hence automatically learning from the network. This Solution intends to provide a zero touch configuration in a DC Network, and allows an AOS switch to act as a plug and play data center bridge.
1. When a port is connected to a network, the switch control-unit tries to configures the pre-requisite setting for FC ports/FCoE ports to accept the frames for a given auto configuration period.
2. Based on the received frames, respective port related, VLAN & VSAN related configurations will be decided and applied automatically. Once the configuration is applied, the switch learns the FC/FCoE devices connected and establishes required sessions. Within the stipulated time, if the switch could not determine the network topology based on received packets, then the settings applied will be reverted to the original default settings on the respective ports. The Administrator can configure whether auto learned configuration has to be retained over reloads or not.
3. Today, when a data center switch is deployed in a network, the administrator has to know the network topology where the DC bridge is deployed and the administrator has to configure the port roles based on the peer-end device (for ex, if the FCoE port is connected to FCoE Forwarder (FCF), configure the role as FCF_Only, if the FCoE port is connected to ENode directly then configure the port role as EDGE etc and if the FC port is connected to HBA, then configure the port role as F_port, if the FC port is connected to a FC switch (FCS), then configure the port role as NP etc). Once the port configuration is decided, the administrator has to configure the FCoE VLANs, VSANs and need to associate all the FCoE and FC ports to VLANs and VSANs respectively. In wide range of deployments, configuring all the pre-requisites to establish FCoE or FC sessions is a tedious job for any administrator and is error prone because of more user intervention. To address this concern, the proposed system auto configures the DC bridg...
