•Brocade Silkworm 2400/2800; Firmware supported: 2.4.1c
 

Configuring the Brocade 2400/2800 switch:
Certain configuration parameters need to be set on the Brocade switch before it will operate with a standards compliant switch. The following parameters can be changed with the Brocade telnet interface.

switch:admin> configure

  Configure...
 

   Fabric parameters (yes, y, no, n): [no] y
   VC Encoded Address Mode: (0..1) [0]

   Switch Operating Mode (yes, y, no, n): [no] y
   Interoperability Mode: (0..1) [1]

   Zoning Operation parameters (yes, y, no, n): [no] y
   Standard Mode: (0..1) [1]

   

In a mixed fabric with the Cisco SN5428, Brocade and McData switches, Domain IDs must be in the 0x61-7f range. If a qLogic SANbox 1Gb switch is in the fabric, this is further restricted to 0x61-6f or 70-7f. The Domain ID can be set with the Brocade telnet interface.

switch:admin> configure

  Configure...
     Fabric parameters (yes, y, no, n): [no] y
   Domain: (97..127) [97]
   
Known Issues with Cisco SN5428 and Brocade operation:
 
  • The Cisco SN5428 supports 2 modes of treating devices when there is no active zoneset, either visible to each other or visible to none. When operating with a Brocade switch, the SN5428 switch should be set to no orphan visibility. Do this by executing the CLI command "interface fc zoning default all".
  • When zoning, the SN5428 accepts zone members as WWNs and only through merges from other switches in the FC fabric.  You must establish and manage zones from a Brocade or other switch.. Brocade switches accept only the WWN specification
   
•Brocade Silkworm 3800; Firmware supported: 3.0.2a
   

Configuring the Brocade 3800 switch:
Certain configuration parameters need to be set on the Brocade switch before it will operate with a standards compliant switch. The following commands must be entered from the Brocade telnet interface.

switch:admin> switchdisable
switch:admin> interopmode 1
switch:admin> fastboot

• McData ED-5000; Firmware supported: 04.00.00.01
   
Configuring the McData switch:
Certain configuration parameters need to be set on the McData switch before it will operate with a standards compliant switch. The following parameter can be changed with the McData GUI.
   
 
  • In the Hardware View window, bring up the Operating Mode window and set "Interop Mode" to "Open Fabric 1.0"

  • In a mixed fabric with SANbox2, Brocade and McData switches, Domain IDs must be in the 0x61-7f range. If a SANbox 1Gb switch is in the fabric, this is further restricted to 0x61-6f or 70-7f. Note that in the McData GUI, the Domain IDs are listed as 1-15 which does equate to 0x61-7f
