12 Limitations and restrictions of Traffic Isolation Zoning TI over FCR is not backward compatible with Fabric OS v6.0.x or earlier. The -1 in the domain,index entries causes issues to legacy switches in a zone merge. Firmware downgrade is prevented if TI over FCR zones exist. Additional configuration rules for enhanced TI zones Enhanced TI zones (ETIZ) have the following additional configuration rules: • Enhanced TI zones are supported only on the following platforms: Brocade 300, 5100, 5300, 5410, 5424, 5450, 5460, 5470, 5480, 7800, 8000, VA-40FC, DCX, DCX-4S, and Brocade Encryption Switch. Enhanced TI zones are not supported on the Brocade 4100, 4900, 5000, 7500, 7500E, 7600, and 48000. • Enhanced TI zones are supported only if every switch in the fabric is ETIZ capable. A switch is ETIZ capable if it meets the following qualifications: - The switch must be one of the supported platforms, as listed above. - The switch must be running Fabric OS v6.4.0 or later. • If the fabric contains a switch running an earlier version of Fabric OS, you cannot create an enhanced TI zone. You cannot merge a downlevel switch into a fabric containing enhanced TI zones, and you cannot merge a switch with enhanced TI zones defined into a fabric containing switches that do not support ETIZ. NOTE FC router domains and EOS switches are excluded from the ETIZ platform restrictions. You can create enhanced TI zones with these switches in the fabric. Trunking with TI zones Note the following if you implement trunking and TI zones: • To include a trunk group in a TI zone, you must include all ports of the trunk in the TI zone. • Trunked ISL ports cannot be members of more than one TI zone. Limitations and restrictions of Traffic Isolation Zoning The following are limitations of TI zones: • For switches running Fabric OS 6.1.0 or later, a maximum of 255 TI zones can be created in one fabric. For switches running Fabric OS 6.0.x, no more than 239 TI zones should be created. A fabric merge resulting in greater than the maximum allowed TI zones results in merge failure and the fabrics are segmented. • A TI zone can be created using D,I (Domain, Index) notation only, except for TI zones in a backbone fabric, which use port WWNs. See "Traffic Isolation Zoning over FC routers" for information about TI zones in a backbone fabric. • To include a trunk group in a TI zone, you must include all ports of the trunk in the TI zone. 278 Fabric OS Administrator's Guide 53-1001763-01
