Limitations and Restrictions Send documentation comments to [email protected] Reserved VSAN Range and Isolated VSAN Range Guidelines On an NPV switch with a trunking configuration on any interface, or on a regular switch where the feature fport_channel_trunk command has been issued to enable the Trunking F PortChannels feature, follow these configuration guidelines for reserved VSANs and the isolated VSAN: • If trunk mode is on for any of the interfaces or NP PortChannel is up, the reserved VSANs are 3040 to 4078, and they are not available for user configuration. • The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for user configuration. The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface standard: VF_ID Value 00h 001h ... EFFh F00h ... FEEh FEFh FF0h ... FFEh FFFh FEFh = 4079 Value Description Do not use as a Virtual Fabric Identifier. Available as a Virtual Fabric Identifier. Reserved. Control VF-ID (see Fibre Channel Link Services (FC-LS) and Fibre Channel Switch Fabric Generation 4 (FC-SW-4) standards). Vendor specific. Do not use as a Virtual Fabric Identifier. Applying Zone Configurations to VSAN 1 In the setup script, you can configure system default values for the default-zone to be permit or deny, and you can configure default values for the zone distribution method and for the zone mode. These default settings are applied when a new VSAN is created. However, the settings will not take effect on VSAN 1, because it exists prior to running the setup script. Therefore, when you need those settings for VSAN 1, you must explicitly issue the following commands: • zone default-zone permit vsan 1 • zoneset distribute full vsan 1 • zone mode enhanced vsan 1 Running Storage Applications on the MSM-18/4 The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time. RSPAN Traffic Not Supported on CTS Ports on 8-Gbps Switching Modules An inter-switch link (ISL) that is enabled for Cisco TrustSec (CTS) encryption must be brought up in non-CTS mode to support remote SPAN (RSPAN) traffic on the following modules: Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1) 28 OL-25090-01
