Interconnect brocade to cisco Fabric - Avoid Fabric Merge

Hi @,

 

Working on solution which will require us to interconnect Brocade Fabric to Cisco fabric, where the driving principles are to avoid fabric Merge and allow resrouce sharing between the two.

 

As we would be looking to prevent any service disruption and we already have FCR configured/licensed on Brocade side, we are favoring the use of FCR vs. AG.

 

Also is unclear, if in fact AG could be used to avoid Fabric Merge.

With that in mind we have the following High Level plan;

  • Have FCR enabled Brocade Switch (already done and working on Brocade Fabric)
  • Set Cisco to Interop Mode 3
  • Migrate Brocade LSANs Zoning config to Cisco Production VSAN
  • Enable IFL from Brocade Base Switch (EXport) to Cisco Switch (Eport) on Production VSAN

 

As an alternative, we are aware that from Cisco we have the support to interconnect between different vendors, and the possibility to use IVR to avoid fabric merge.

 

Many thanks in advance for sharing your suggestions and comments on how we could approach this and meet the solution principles.

Jorge,

 

-->>Also is unclear, if in fact AG could be used to avoid Fabric Merge.

I assume with AG you mean "Access Gateway" ? in this case the answer is NO!. Switch in AG Mode work as simple ISL, whit the advantage to reduced Cabling.

 

-->>>Have FCR enabled Brocade Switch

-->>Set Cisco to Interop Mode 3

 

what type/model of Switch ? FOS Release ?

 

depend of switch Type/Model and FOS Rel., Interop-Mode is no longer supported on some Brocade Plattforms.

 

you shold post a bit more Info about your environments.

Re: Interconnect brocade to cisco Fabric - Avoid Fabric Merge

Hi Antonio/Brocate Team,

 

Many thanks for the quick follow up.

Correct.. I was refering to Access Gateway (AG) Mode.

 

Quick insight into SAN infra.

Brocade:

- DCX and DCX-4S Switches using FOS 6.4.2a

- DCX are on site A and DCX-4S on site B

- Logical Switches (LS) configured

- FCR being used to enable Inter-Fabric interconnectivity and resource sharing between sites

 

Cisco:

- MDS 9148S Switches using SAN-OS 6.2(9)

- Installed on site B as per DCX-4S

 

Brocade to Cisco Interconnectivity Approaches being reviewed

1- Local Interconnect (Cisco to Brocade DCX-4S both in site B)

    * EXport on Base switch configured on DCX-4S to Eport on configured on Production VSAN on Cisco

    * Use existing XISLs on Brocades on each site to enable resource sharing with Cisco (Long Distance Links within the Base Fabric)

 

2- X-site Interconnect (Cisco in site B to DCX in site A)

   * Long distance links to cisco Edge Fabric using CWDM

    * EXport on Base switch configured on DCX to Eport on configured on Production VSAN on Cisco

 

We are aware that is not considered a Best Practice to use 'Remote Edges', but we would aim with this in the short term enable load balancing resources between DCX-4S and Cisco in site B.

 

Many thanks once again for your availability and assistance and looking forward to your feedback.
