Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m . Maximum Number of Zones Supported in Interop Mode 4 In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to limitations in the connected vendor switch. When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones, in the active zone set is 2047.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m . Table 9 Open Caveats and Resolved Caveats Reference (continued) Software Release (Open or Resolved) DDTS Number 3.1(3) 3.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m . • ICSCsi77055 Symptom: An MDS switch that provides IVR routing on a local VSAN may not be able to export new devices via IVR if there are multiple IVR routers in the local VSAN or if one IVR router contains stale entries for a device. When an IVR router has stale information, it will be out of sync with the other IVR routers.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m . Open Caveats • CSCei82909 Symptom: The implementation of the Internet Key Exchange (IKE) version 2 in Cisco MDS 9000 switches may not be interoperable with other IKE version 2 implementations. The Cisco MDS 9000 IKE version 2 implementation is used whenever an encrypted FCIP tunnel is established between two MDS switches.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m . This issue has no effect on functionality. However, debug messages and syslogs from the MDS switching modules have incorrect timestamps if the time zone is configured on an MDS switch. Workaround: None. • CSCsg19303 Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.
