3 Hardware S4820T Series AC Power supply with airflow from power supply unit (PSU) side to I/O side NOTE: Fan Modules and Power supplies (PSUs) are field replaceable units. Dell Networking does not support a mix of power supply types (i.e., AC and DC) in the same switch. NOTE: All fans and PSUs must have the same airflow direction. Should a mixed airflow configuration happen, the switch detects the discrepancy and performs a shutdown, if the module is not replaced within few minutes. NOTE: Due to hardware limitation, 1G copper and fiber SFP with QSA is not supported. New Dell Networking OS Version 9.10(0.1) Features The following new software features have been added in Dell Networking OS version 9.10(0.1) on the S4820T. Please see the Dell Networking OS Configuration Guide and Dell Networking OS Command-Line Reference Guide for details regarding configurations, restrictions, and usage. Feature Energy Efficient Ethernet Internal BGP next hop self Description Energy Efficient Ethernet (EEE) is an IEEE az standard that reduces power consumptions on Ethernet ports. EEE stops the transmission when there is no data to be transmitted and resumes the transmission at the arrival of new packets. You can enable EEE only on one Gigabit and ten Gigabit native or optional module copper ports. Dell Networking OS enhances the capability of route reflectors to set its own IP address as the next hop for both ibgp and ebgp-learned routes. Restrictions If an Intel X520 CNA adapter is used as an FCoE initiator, follow these steps to establish FCoE sessions to send and receive traffic on an S4820T switch: 1 On the server, uninstall the old Intel driver (version or older). 2 Re-install the Intel driver using version 13.5 A00 (or later) from the 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 Dell Networking OS does not support encapsulated remote switched port analyzer (ERSPAN) and remote switched port analyzer (RSPAN) in a VLT setup. Dell System S4820T 9.10(0.1P17) 3

4 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) Changes to Default Behavior and CLI Syntax Dell Networking OS enhances the show hardware drops command to display the number of dropped packets in the ingress buffer. For SCP, FTP, and HTTP copy operations done through external servers, the password you specify can be a string of up to 32 characters in length. Dell Networking OS enhances the show hardware stack-unit command to display the data plane or management plane input and output statistics of the designated component of the designated stack member. Dell Networking OS enhances the show hardware buffer interface command to display the buffer statistics for a specific interface. Dell Networking OS enhances the show hardware buffer-stats-snapshot command to display the buffer statistics tracking resource information for a specific interface. Dell Networking OS enhances the show hardware stack-unit buffer-stats-snapshot command to view the buffer statistics tracking resource information depending on the type of buffer information. The buffer information comprises of device-level details, port-level counters, queue-based snapshots, or priority group-level snapshot in the egress and ingress direction of traffic. Dell Networking OS enhances the show hardware counters interface command to display the counter information for a specific interface. The system displays whether there is a change in privilege or role to the administrator s account since last login. DNS Query support for both IP and IPv6: In a dual stack setup, the system sends both A (request for IPv4 RFC 1035) and AAAA (request for IPv6 RFC 3596) record requests to a DNS server even if only the ip name-server command is configured. You can use the show pfc statistics command even without enabling DCB on the system. Support for hmac-sha hashing algorithm option is discontinued. SupportAssist is enabled by default on the system.

Dell# 3 Check whether the CPLD has been upgraded to the latest version. show revision EXEC PRIVILEGE Dell#show revision -- Stack unit 0 -- S4820 SYSTEM CPLD : 9 NPU PCI DEVICE ID : 0xB846 (TRIDENT+) Dell# VLT Upgrade Procedure To upgrade the Dell Networking OS in a VLT setup from version 9.2(0.0) to the latest version, upgrade Dell Networking OS to version 9.3(0.0) first and then to the newer version. If you are already running Dell Networking OS version 9.3(0.0) or later, you can directly upgrade the Dell Networking OS to the latest version. To upgrade the Dell Networking OS, on systems running VLT, perform the following steps: 1 Upgrade the system-flash partition A or B with the new image on both VLT peers.on both the VLT peers, set Primary boot parameter to boot the system from upgraded system flash partition [A or B]. You can enter one of the following options: flash Copies from flash file system (flash://filepath).ftp Copies from remote file system (ftp://userid:password@hostip//filepath).scp Copies from remote file system (scp://userid:password@hostip//filepath).tftp Copies from remote file system (tftp://hostip/filepath). upgrade system [flash: ftp: scp: tftp: usbflash:] [A: B:] EXEC Privilege 2 Reload or power-cycle one of the VLT peers (For Example, Peer 2). reload or power cycle 3 Wait for Peer 2 to come up; VLT adjacency will be established. (Peer 2 - new image and Peer 1 - old image). 4 Wait for the Peer 2 to bring up all VLT LAG ports. Use the command show vlt detail to confirm all VLT ports in the local chassis are active. show vlt detail EXEC Privilege 5 Following upgrade, use the write memory command to save the running-config to memory. write memory EXEC Privilege 6 Ensure both the nodes are now forwarding traffic. 10 Dell System S4820T 9.10(0.1P17)

11 NOTE: You can upgrade VLT Nodes from 9.3 tο , 9.4 tο , 9.5 to , 9.6 to , 9.7 tο and 9.8 to When all VLT ports are active on the Peer 2, repeat steps 2 through 5 for the Peer 1. NOTE: After upgrading to the latest Dell Networking OS version, upgrade the CPLD if required. Documentation Corrections This section describes the error identified in the current releases of the Dell Networking OS. The Dell Configuration Guide for the S6000-ON System and Dell Command Line Reference Guide for the S6000-ON System mention that the system supports up to eight ACL VLAN groups. But the system supports up to 31 ACL VLAN groups. The Dell Networking OS Command Line Reference Guide incorrectly mentions a note on multi-process OSPF. It will be corrected in the next release by including the following note: The Dell Networking OS versions 9.4(0.0) and 9.7(0.0) introduce support for VRF on OSPFv2 and OSPFv3 respectively. The multi-process OSPF feature supported on Dell Networking OS version is modified. In earlier versions, multiple OSPF processes were created without VRF (prior to 9.4(0.0)). In the Dell Networking OS versions 9.4(0.0) and 9.7(0.0) (for OSPFv3), multiple OSPF processes can be created on a router, but with only one OSPF process per VRF. However, there can be one OSFPv2 and one OSPFv3 on the same VRF. The following note will be added to Open Shortest Path First (OSPFv2 and OSPFv3) topic of the Dell Networking OS Command Line Reference Guide: OSPFv2 is supported on IPv6 tunnels only and OSPFv3 is supported on IPv4 tunnels only. The following Usage Information will be added to router ospf command of the Dell Networking OS Command Line Reference Guide: You can create only one OSPFv2 process per VRF. Deferred Issues Issues that appear in this section were reported in Dell Networking OS version 9.10(0.1) as open, but have since been deferred. Deferred caveats are those that are found to be invalid, not reproducible, or not scheduled for resolution.
