Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(4d)
OL-21012-06
Limitations and Restrictions
The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface
standard:
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:
• DS-X9248-96K9: Cisco MDS 9000 48-Port 8-Gbps Fibre Channel Switching Module
• DS-X9224-96K9: Cisco MDS 9000 24-Port 8-Gbps Fibre Channel Switching Module
• DS-X9248-48K9: Cisco MDS 9000 4/44-Port Host-Optimized 8-Gbps Fibre Channel Switching
Module
If the ISL link is brought up with CTS enabled, random packets drops of both RSPAN traffic and normal
traffic will occur on the receiver port switch.
