New Dell Networking OS Version 9.14(1.12) Features

The following features have been added to the MXL with Dell Networking OS version 9.14(1.12):
None.

Restrictions

• Fanning out SM4 optics is not supported.

• If you want to downgrade from Dell Networking OS version 9.14(1.12) to an earlier version, you must power cycle the I/O modules using CMC.

• QSFP+ High-Power Optics Usage — Scenarios

  • High-Power Optics is Inserted and Peer Port has No Optics — The peer port is disabled. The peer port gets enabled right after the high-power optics are removed. Both ports are available in the case of low power optics (40G SR4/CR4). The system generates the following syslog:
    INSERT_OPTICS_HP_QSFP_PEER_PORT_DISABLE: Optics 40GE High power QSFP+ is inserted in port 0/33 and peer port 0/37 is disabled for Optics as only one High power optic can be enabled.
    High-Power Optics is Inserted and Peer Port has High / Low Power Optics — The current port will be locked as peer port is already in use, and the system can only support a high-power optic or a pair of low-power optics in fixed ports, as well as in a QSFP module. The user can remove any one of these optics based on their requirement. The system generates the following syslog:
    INSERT_OPTICS_HP_QSFP_PORT_DISABLE: Optics 40GE High power QSFP+ is inserted in port 0/49 and it is not activated unless peer port 0/53 optics is removed as only one High power optic can be enabled. Please remove any one of the optics to avoid any potential thermal overheating to the hardware.

  • Low-Power Optics is Inserted and Peer Port has High-Power Optics — The current port is already locked because of the peer port high-power optics. So the current port is already in disabled state. The user can remove any one of these optics based on their requirement. The system generates the following syslog:
    INSERT_OPTICS_QSFP_DISABLED_PORT: Optics 40GE QSFP+ is inserted in port 0/49 and it is not activated unless peer port 0/53 High Power optics is removed as only one High power optic can be enabled. Please remove any one of the optics to avoid any potential thermal overheating to the hardware.

• If an Intel X520 CNA adapter is used as an FCoE initiator, follow these steps to establish FCoE sessions to send and receive traffic:

1. On the server, uninstall the old Intel driver (version 13.0.0 or older).

2. Re-install the Intel driver using version 13.5 A00 (or later) from the http://www.dell.com website.
   Important: During the installation, do not select the ISCSI part of the driver; select only the FCoE check box.

3. On each server-facing port, enter the following commands in Interface Configuration mode. The dcbx version cee command configures a port to use the CEE (Intel 1.01) version of DCBX. Configure server-facing ports with the shutdown and no shutdown commands as needed.
   For example:
   Dell# interface tenGigabitEthernet 0/1
   Dell(conf-if-te-0/1)# portmode hybrid
   Dell(conf-if-te-0/1)# switchport
   Dell(conf-if-te-0/1)# protocol lldp
   Dell(conf-lldp)# dcbx port-role auto-downstream Dell(conf-lldp)# dcbx version cee
   Dell(conf-lldp)# exit
   Dell(conf-if-te-0/1)# spanning-tree pvst edge-port Dell(conf-if-te-0/1)# no shutdown
   Dell(conf-if-te-0/1)# exit
   Dell#

4. Display information on FIP-snooped sessions and check the entries in ENode Interface fields to see if you have established the FCoE session on a server-facing port.

show fip-snooping sessions EXEC Privilege

• The following features are not available in the Dell Networking OS from version 9.7(0.0):

  • PIM ECMP
  • Static IGMP join (ip igmp static-group)
  • IGMP querier timeout configuration (ip igmp querier-timeout)
  • IGMP group join limit (ip igmp group join-limit)

• If the MXL switch is in boot-line interface (BLI) mode:

  • You cannot switch to the CMC console and manage the switch using CMC.
  • You cannot disconnect and reconnect to CMC from the CMC console.
    NOTE: Connect to the CMC console after you exit the BLI interface or after the BLI phase of the bootup finishes.

• After you upgrade the CPLD version on an MXL switch using the BLI, the new CPLD version is not displayed in show revision output if you power cycle the switch using the power-cycle stack-unit command. Instead, power cycle the MXL switch using the CMC interface.

• The MXL switch crashes and reboots when an FRU read operation fails.

• When FRRP is enabled in a VLT domain, no flavor of Spanning tree should concurrently be enabled on the nodes of that specific VLT domain. In essence FRRP and xSTP should not co-exist in a VLT environment.

• While deploying the system in the normal-reload mode in BMP configuration, use the ip ssh server enable command at the beginning of the startup configuration if the write memory command is used at the end of the configuration.

Changes to Default Behavior and CLI Syntax
Following default behavior and CLI syntax changes occurred during the Dell Networking OS release:

• To enhance security, the default RSA key size has been changed to 2048 bits from 1024 bits from 9.14.1.10 onwards.
