MDS 9000 Switch and McData Dual Core Topology (Interop Mode 1)

This chapter describes how to set up a basic dual-core topology with an MDS 9000 switch configured for interop mode 1 and a McData 6064 switch. Devices are connected to both core switches and all traffic must flow through both cores to reach its destination.

This chapter includes the following sections:

•Specifications

•Expected Topology Behavior

•Configuration

•Verification

•Zoning

Specifications

The following switches and code levels were used for this example configuration:

•MDS 9509 running SAN-OS Release 1.0(1)

•McData 6064 Version 04.01.00 12

Figure 5-1 shows the topology used for this example configuration.

Figure 5-1 MDS 9509 Switch and McData Switch Dual Core Topology

Note The VZ1 JBOD is an arbitrated loop with 7 private drives.

Expected Topology Behavior

This section covers the Fibre Channel services and features that act differently in this topology (Figure 5-1) as compared to a homogeneous, single-vendor implementation.

It contains the following topics:

•Zoning

•FSPF

•Trunking and PortChannels

•Domain IDs

Zoning

In the core-core topology, zone members are all pWWNs, because the McData domain/port nomenclature is not a valid form according to the FC standard. When a zone set activation is made at one core switch, the zone set activation is sent to the other core switch. Either core switch may make zoning changes and have them be propagated to the other core switch.

Both core switches provide all of the zone security for the device attached ports because the MDS 9000 switch and the McData switches do not check the source and destination of the frame when traversing E ports. The MDS 9000 switch only provides hardware enforced security on the ingress ports to the fabric, while the McData switch only provides soft zoning.

Note After two active zone sets successfully merge, always copy the active zone set to the full zone set database prior to modifying it on the MDS 9000 switch.

FSPF

All links within the topology show the link cost of 1000, because the McData 6064 switch used in this example only supports 1Gbps.

The McData switches load balance their routes using source/destination; the ingress edge switch uses the same ISL for all traffic that has the same source/destination pair. If the McData switch can load balance using source/destination/ox-id, then it can choose either of the ISLs for the route through the fabric. The MDS switch continues to load balance across ISLs using source/destination/ox-id of the frame.

Trunking and PortChannels

The lack of MDS 9000 switch-to-MDS 9000-switch connections prohibits the topology from containing TE ports or PortChannels. Only standard E ports are used for the ISLs.

Domain IDs

The domain IDs are limited to the 97 to 127 range due to a restriction imposed by McData's inability to handle IDs outside of that range. While the MDS 9000 switch can handle domain IDs outside of this range in its normal mode of operation, the implementation of interoperability mode includes this limitation.

Domain ID modifications can be handled in two ways, disruptively or nondisruptively:

•Disruptive—This event impacts the entire switch. When changing domain IDs, McData requires the entire switch to be taken offline and/or rebooted.

•Nondisruptive—This event is limited to the VSAN where the event is taking place. Only the MDS 9000 switch can perform this action, as the domain manager process for this VSAN is restarted and not the entire switch. This restart requires any device logged into the VSAN to log into the fabric again to obtain a new FC ID.

Configuration

This section describes the configuration process and includes the following topics:

•Configuring the McData 6064 Switch

•Configuring the MDS 9000 Switch

Configuring the McData 6064 Switch

In this example, the McData 6064 switch is configured for interop mode using Telnet and the CLI. The switch is placed in an offline state, the default zone is set to deny, the domain ID is set to 0x61 (97), and timers are altered to match the fabric.

Follow these steps to configure the McData 6064 switch.

Step 1 Display current switch information.

Devices are connected to both core switches and all traffic must flow through both cores to reach its destination. This chapter includes the following sections: •Specifications •Expected Topology Behavior •Configuration •Verification •Zoning Specifications The following switches and code levels were used for this example configuration: •MDS 9509 running SAN-OS Release 1.0(1) •McData 6064 Version 04.01.00 12 Figure 5-1 shows the topology used for this example configuration. Figure 5-1 MDS 9509 Switch and McData Switch Dual Core Topology Note The VZ1 JBOD is an arbitrated loop with 7 private drives. Expected Topology Behavior This section covers the Fibre Channel services and features that act differently in this topology (Figure 5-1) as compared to a homogeneous, single-vendor implementation. It contains the following topics: •Zoning •FSPF •Trunking and PortChannels •Domain IDs Zoning In the core-core topology, zone members are all pWWNs, because the McData domain/port nomenclature is not a valid form according to the FC standard. When a zone set activation is made at one core switch, the zone set activation is sent to the other core switch. Either core switch may make zoning changes and have them be propagated to the other core switch. Both core switches provide all of the zone security for the device attached ports because the MDS 9000 switch and the McData switches do not check the source and destination of the frame when traversing E ports. The MDS 9000 switch only provides hardware enforced security on the ingress ports to the fabric, while the McData switch only provides soft zoning. Note After two active zone sets successfully merge, always copy the active zone set to the full zone set database prior to modifying it on the MDS 9000 switch. FSPF All links within the topology show the link cost of 1000, because the McData 6064 switch used in this example only supports 1Gbps. The McData switches load balance their routes using source/destination; the ingress edge switch uses the same ISL for all traffic that has the same source/destination pair. If the McData switch can load balance using source/destination/ox-id, then it can choose either of the ISLs for the route through the fabric. The MDS switch continues to load balance across ISLs using source/destination/ox-id of the frame. Trunking and PortChannels The lack of MDS 9000 switch-to-MDS 9000-switch connections prohibits the topology from containing TE ports or PortChannels. Only standard E ports are used for the ISLs. Domain IDs The domain IDs are limited to the 97 to 127 range due to a restriction imposed by McData's inability to handle IDs outside of that range. While the MDS 9000 switch can handle domain IDs outside of this range in its normal mode of operation, the implementation of interoperability mode includes this limitation. Domain ID modifications can be handled in two ways, disruptively or nondisruptively: •Disruptive—This event impacts the entire switch. When changing domain IDs, McData requires the entire switch to be taken offline and/or rebooted. •Nondisruptive—This event is limited to the VSAN where the event is taking place. Only the MDS 9000 switch can perform this action, as the domain manager process for this VSAN is restarted and not the entire switch. This restart requires any device logged into the VSAN to log into the fabric again to obtain a new FC ID. Configuration This section describes the configuration process and includes the following topics: •Configuring the McData 6064 Switch •Configuring the MDS 9000 Switch Configuring the McData 6064 Switch In this example, the McData 6064 switch is configured for interop mode using Telnet and the CLI. The switch is placed in an offline state, the default zone is set to deny, the domain ID is set to 0x61 (97), and timers are altered to match the fabric. Follow these steps to configure the McData 6064 switch. Step 1 Display current switch information.

Figure 5-3 shows the fabric topology from Fabric Manager. Figure 5-3 MDS 9000 Switch and McData Dual Core Displayed in Fabric Manager Figure 5-4 shows Device Manager on the MDS 9509 switch in the example topology. It shows which ports are active as E ports. Figure 5-4 MDS 9509 Switch Device Manager Showing Active Ports Figure 5-5 shows the status of the E ports and can verify link speed. Figure 5-5 Fabric Manager Verifying Port Status and Type Figure 5-6 shows the domain ID of the switches in the fabric. Figure 5-6 Fabric Manager Verifying Domains Figure 5-7 shows that VSAN 99 is operating in interop mode. Figure 5-7 Verifying Interop Mode is Set Figure 5-8 shows the MDS 9509 switch name server. This shows the edge devices that have registered. Figure 5-8 MDS 9509 Switch Name Server Entries Figure 5-9 shows the FSPF routes as calculated by this switch. Figure 5-9 FSPF Calculations in Fabric Manager Zoning In this example topology, Fabric Manager was used to create zones and zone sets. Fabric Manager displays are also used to verify the zone and zone set information. Figure 5-10 shows the zones and zone sets displayed in Fabric Manager.
