OL-14116-03
Limitations and Restrictions
• SPAN—1 session maximum
Cisco MDS 9222i Multiservice Modular Switch and Cisco MDS 9000 18/4-Port
Multiservice Module
The Cisco MDS 9222i Multiservice Modular Switch and the Cisco MDS 9000 18/4-Port Multiservice
Module (MSM-18/4) support one iSCSI forwarding mode that is equivalent to store-forward on the
MPS-14/2 module.
The Cisco MDS 9222i switch and the MSM-18/4 module support header-digest, but not data-digest in
Cisco SAN-OS 3.2(2c).
The Cisco MDS 9222i switch and the MSM-18/4 module do not support Ether channel.
The Cisco MDS 9222i switch supports only the following modules in slot 2:
• The Storage Services Module (SSM)
• The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4)
• The 8-port Gigabit Ethernet IP Storage services module
• The MDS 9000 12-, 24-, and 48-port 4-Gbps Fibre Channel modules
• The MDS 9000 4-port 10-Gbps Fibre Channel module
The MSM-18/4 module and MDS 9222i switch do not support the following features:
• Special frames for FCIP
• B ports for San Extension
• SAN extension tuner
• NetSim
• IPv6
• FCIP between the MSM-18/4 module and another IPS module
Using SAN Device Virtualization on Cisco Fabric Switches
There must be at least one SAN device virtualization-enabled switch that is not a Cisco MDS 9124
switch, a Cisco Fabric Switch for HP c-Class BladeSystem, or a Cisco Fabric Switch for IBM
BladeCenter between the server and the target that are being virtualized. In other words, SAN device
virtualization does not work when initiators and primary targets are connected to the same Cisco MDS
9124 Switch or or Cisco MDS 9134 Switch or Cisco Fabric Switch for HP c-Class BladeSystem or Cisco
Fabric Switch for IBM BladeCenter.
