Documentation Updates
Because the entire hardware and software documentation set is not being published for Release 9.3.0.0,
similar to the earlier major releases, this section has been organized to present behavioral-changes and
enhancements to commands and configuration settings that have been implemented in Release 9.3.0.0.
We recommend that you read this section in conjunction with the full-blown documentation set of
Release 9.2.0.0 of the different platforms.
• Starting with Dell Networking OS Release 9.3.0.0, on an I/O Aggregator, you can enable and disable
the DCB capability without having to reload the switch. The on-next-reload option available with
the [no] dcb enable command is not required when you enter this command. Until Release
9.2.0.0, you could enable or disable DCB only by specifying the on-next-reload keyword, which
caused DCB to be activated or deactivated only during the subsequent reload of the switch. Similarly,
you can configure automatic detection of DCB and DCBx by using the
dcb enable auto-detect
command without the on-next-reload keyword.
The enhanced syntax of the dcb enable command is as follows:
[no] dcb enable [auto-detect]
The enhanced syntax of the dcb enable command is as follows:
dcb enable auto-detect [on-next-reload]
• The following note applies to the Enhanced VLT section of the VLT chapter of the relevant platforms'
Configuration Guides:
In an enhanced VLT (eVLT) configuration, if different virtual router identifiers (VRIDs) are configured in
the two VLT domains that are part of the same Layer 2 domain, and if you enable generation of SNMP
traps for VRRP in the devices of both the VLT domains by using the snmp-server enable traps
vrrp
command, a large number of traps are received on the device that receives the VRRP traps for
state changes because traps are generated every second and the alarm trap application is throttled.
• The following note applies to the rate-shape command topic of the QoS chapter of the S6000
Command Reference Guide:
On the S6000 platform, hierarchical QoS does not support policy-based rate shaping if you configure
a unicast queue as a strict-priority (SP) queue.
• The following note applies to the Private VLAN Concepts section of the PVLAN chapter of all
platforms' Configuration Guides:
On the S4810 platform, stale and incorrect entries are added to the MAC address table and CAM when
movement of multiple stations occurs across the primary and secondary private VLANs. Because
PVLAN uses VLAN translation tables, the station movement is not detected if such a shift of station
occurs in a single PVLAN domain.
• The following additional information applies to the Private VLAN Concepts section of the PVLAN
chapter of all platforms' Configuration Guides:
In a VLAN domain that contains two VLT peer nodes connected by the VLT interconnect link (VLTi)
and with IGMP snooping and PIM enabled in the VLAN, IGMP queries generated by one peer are sent
to the other peer that contains an orphan port and forwaded out of it. This behavior occurs when the
peer that functions as the IGMP querier contains an extended ACL with deny action configured and
