Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(6)

OL-27554-01

Limitations and Restrictions

• Configuring a Persistent FCID in an IVR Configuration with Brocade Switches, page 39

SME Quorum

You cannot change the quorum or the SME master node during a master key rekey. If a change occurs

during the smart card portion of the operation, the master key rekey operation will fail and must be

repeated from the beginning.

OUI Mismatch for SME Tape Targets

If Cisco DCNM does not discover all expected tape targets, check the sme.log to identify an OUI

mismatch. Look for a message like the following:

2012.04.09 21:15:50 WARN [SME] skipped target 50:06:0b:00:00:b8:e4:b0 due to explicit

type mismatch. Expect: 240 found: 228. If this is an error update your OUI definitions

To correct this issue, manually add the OUI definitions to the server.properties file. The format is as

follows:

mds)

# for example: newOUIs=0x00E069 JNI h|d; 0x000ded Cisco m;\

# 0x006069 Brocade s;

newOUIs=

FCIP Performance Drop

FCIP performance can drop in a topology where the round-trip time (RTT) delay is configured at 80 ms,

IPSec is enabled, and write acceleration (WA) is not used.

FCoE Module

• In Cisco MDS NX-OS Release 5.2(x), you cannot install a FCoE module in a switch that is running

DMM, SME, or IOA.

• Link traps for FCoE devices are sent only when a VFC interface flaps.

IPv6

The management port on Cisco MDS switches supports one user-configured IPv6 address, but does not

support auto-configuration of an IPv6 address.

User Roles

In SAN-OS Release 3.3(x) and earlier, when a user belongs to a role which has a VSAN policy set to

Deny and the role allows access to a specific set of VSANs (for example, 1 through 10), the user is

restricted from performing the configuration, clear, execute, and debug commands which had a VSAN

parameter outside this specified set. Beginning with NX-OS Release 4.1(1b), these users are still
