Release Notes
Dell EqualLogic arrays are required to be upgraded to firmware 5.0.2 or later in order to use the iSCSI Optimization
feature.
 LLDP
Administrators should ensure that LLDP-MED is enabled in order to operate EEE. Disabling LLDP or LLDP-MED
will effectively disable EEE, IEEE 802.3at PoE+ high power negotiation and Dell EqualLogic array detection in the
iSCSI Optimization feature.
 Connectivity Fault Management
Connectivity Fault Management performs Metro Ethernet maintenance functions. Dell PowerConnect CFM supports
the following functions defined in IEEE 802.1ag Draft 8.1:
•
Path discovery (link trace messages)
•
Fault detection (continuity check message)
•
Fault verification and isolation (loopback and link trace messages)
•
Fault notification (alarm indication signal or SNMP trap).
 Management IP Address Conflict Detection
Management IP address conflict detection actively looks for duplicate IP address assignment and logs conflicts. Only
the last identified IPv4 address conflict is retained for display by a show command. Administrators may examine the
in- memory logs or the output from a SYSLOG server to identify the historical IP address conflicts. If console logging
is enabled for traps, a message will appear on the console indicating that an address conflict has occurred.
 Email Alerting
Email alerting allows administrators to be notified via email regarding system events. Multiple email addresses can be
configured. The system will attempt to resolve mail servers specified with a FQDN immediately and, if successful,
store the mail-server as an IP address. If a new IP address is subsequently assigned to the mail server, the operator will
need to re-assign the email address on the switch.
Only the Mail User Agent functionality of RFC 4409 is implemented. The PowerConnect switch does not implement
SMTP server functionality.
 802.1X Monitor Mode
Monitor mode is a special debug mode that assists network administrators in configuring 802.1X authenticators. Users
attempting to authenticate using the authenticator are always granted access when monitor mode is enabled. All
interactions with the supplicant and the authentication server are logged.
Administrators are cautioned against enabling monitor mode in a deployed network where 802.1X users may gain
access to sensitive network resources.
 Time Controlled ACLs
Time controlled ACLs allow administrators to apply ACLs based on the time of day. Both periodic and absolute time
periods may be configured.
Administrators are cautioned that invalid (overlapping) periodic entries within a time range will prevent the time range
from being applied. Administrators are advised to test their periodic entries and validate that they become active as
expected before deploying the time ranges in a production network. Administrators can check if a time range is active
by using the show time-range command.
It is recommended to enable ACL logging to ensure notice of ACL activation and de-activation.
 SNTP over IPv6
SNTP operates over IPv4 and IPv6 and may be configured using IPv4 or IPv6 addresses or DNS.
