PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Added Functionality in this Release ¾ Non-Stop Forwarding This feature creates an option to allow the forwarding plane of stack units to continue to forward packets while the control and management planes restart as a result of a power failure, hardware failure, or software fault on the stack management unit. This type of operation is called non-stop forwarding. When the management unit fails, only the management switch needs to be restarted.
¾ Serviceability Tracing Commands Debug commands provided to enable tracing of various protocols. ¾ Faster Initialization for Stacking Failover Fast Reinitialization involves improvement in: • Detection of Management Unit Failure • Building Card Manager Database • Application of saved configuration Performance Improvements (based on Configuration File size) are: • Default ~ 35% • Medium ~ 50% • Large ~80% The impact is higher on large configuration files versus the smaller ones.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes ¾ MLD Snooping (RFC2710) In IPv4, Layer 2 switches can use IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only those interfaces associated with IP multicast address. In IPv6, MLD snooping performs a similar function.
¾ RADIUS Enhancements • • • • ¾ The maximum number of RADIUS servers supported has increased from three to 32. RADIUS servers with the same name can be used as Backups (RADIUS Authentication and Accounting servers) Simultaneous Transactions to Multiple RADIUS Servers RADIUS Accounting – Allows a client the ability to deliver accounting information about a user to an Accounting server.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes ¾ Ping/Traceroute Enhancements New ping options have been added to allow the user to specify the number and size of echo requests and the interval between echo requests. A ping can now be initiated via SNMP using the MIB defined in RFC 2925.
¾ Granular OSPF v2/v3 Traps Configure which of the OSPF traps the OSPF Router should generate by enabling or disabling the trap condition. If a trap condition is enabled and the condition is detected, the OSPF router will send the trap to all trap receivers. ¾ auto-cost reference bandwidth and bandwidth Commands Controls how OSPF calculates the default metric for an interface by using the auto-cost command in router OSPF configuration mode.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes ¾ Configured Tunnels MTU To comply with RFC 4213, Basic Transition Mechanisms for IPv6 Hosts and Routers, the IPv6 MTU on configured IPv6 over IPv4 tunnels was changed from 1480 bytes to 1280 bytes. ¾ IPv6 6 to 4 Auto Tunnels The 6 to 4 tunnels automatically formed IPv4 6 to 4 tunnels for carrying IPv6 traffic. The automatic tunnel IPv4 destination address is derived from the 6 to 4 IPv6 address of the tunnel next hop.
¾ IPv6 Management Enhancements Provides the following: ¾ • Dual IPv4/IPv6 operation over the network port • Static assignment of IPv6 addresses and gateways for the service/network ports • Ability to ping an IPv6 link-local address over the service/network port • SNMP traps and queries via the service/network port Updated IPv4 Multicast Routing Support The Multicast package code has been extensively re-engineered and furnished with the following: ¾ • PIM-DM advanced to RFC 3973 • PIM-SM adva
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Changed Functionality in this Release ¾ Spanning Tree Update – 802.1Q-2005 Spanning Tree now supports IEEE802.1Q-2005. This version of the IEEE Multiple Spanning Tree Protocol corrects problems associated with the previous version, provides for faster transition-to-forwarding, and incorporates new features for a port (restricted role and restricted TCN).
¾ ip route Command Changed The syntax of the ip route command has changed. The metric keyword is no longer accepted as it had no effect. The new syntax is: ip route ip addr subnetmask | prefix-length nextHopRtr [ preference ] ¾ distance ospf Command Changed The distance ospf command has been changed (for both OSPFv2 and OSPFv3) to the industry standard syntax.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes ¾ Trap Configuration In previous versions of the software, configuration of the flags for controlling traps was scattered about in a number of places. snmp-server enable traps is now a common command for configuring all trap flags. The legacy commands are preserved for backward compatibility. Also note that the keyword “trap” has changed to the plural “traps”.
¾ ACL Changes The following changes apply to ingress and egress ACLs: o Maximum of 100 ACLs o Maximum rules per ACL are 127 Note: Although the maximum number of ACLs is 100, and the maximum number of rules per ACL is 127, the system cannot support 100 ACLs that each has 127 rules. Note: Any given port can support up to 127 rules. These 127 rules can be in a single ACL or in multiple ACLs that are applied to the interface. Note: ACL’s can be applied to all Ethernet interfaces.

PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Issues Resolved The following is a list of issues resolved in the current firmware release. Description User Impact Resolution Unable to configure IPv6 host (4001::2) as an SNMP trap receiver on the DUT. User is not aware that the only IPv4 address is accepted by the command snmp-server host and so may try to give IPV6 address as input.
Description User Impact Resolution Bridge multicast forbidden forward-unregistered causes L3 Multicast to fail. Flooding in ingress VLAN. Modified the L3 interaction code of snooping to notify the driver when snooping is enabled. When snooping is disabled, the current operational state of snooping is also sent to the driver. Cut-through mode command help is not clear. For normal command and no command the help information is the same.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Description User Impact Resolution Cannot enter Daylight Saving Time from Web interface. In summer time configuration page, in recursive mode, clock zone field is not accepting valid range. In summer time configuration page, in recursive mode, added appropriate regular expression in validation. Error message when changing SNTP Server Priority from Web interface.
Description User Impact Resolution Changing Radius Timeout from Web interface inadvertently changes Priority to same value. Changing the Timeout Duration field on the RADIUS Server Configuration web page would also change the Priority field to the same value. Correct the API to properly set the RADIUS priority. Radius Servers always show active status. The RADIUS Server Status web page was always displaying the server’s status as active.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes CLI Reference Manual Updates Non-Stop Forwarding Title Description nsf Use this command to enable non-stop forwarding. The “no” form of the command will disable NSF. no nsf Default: Non-stop forwarding is enabled by default. show nsf Use this command to show the status of non-stop forwarding. show checkpoint statistics Default: Not applicable Use this command to display the statistics for the check pointing process.
Title Description show ip ospf neighbor This command has been enhanced to list the per neighbor graceful restart status described in the RFC 4750 MIB. Possible values for Restart Helper Status are as follows: • Helping – This router is acting as a helpful neighbor to this neighbor. • Not Helping – This router is not a helpful neighbor at this time.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes RADIUS Accounting Servers Title Description radius-server host acct The switches do not support creating accounting server names with the same name although the CLI Reference Manual and User Guide state that it is supported. Default: Not applicable Spanning Tree Title Description no spanning-tree transmit hold-count The hold-count keyword is not required when resetting the spanning-tree transmit hold-count.
Link Dependency Commands Title Description link-dependency group [ action { up | down } ] Use the action command to control the operational state of the group based on the dependent links state. • • up — Causes the group members to change their operational state to be opposite that of the dependent link. down — Causes the group members to change their operational state to follow that of the dependent link. Default: Not applicable.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Known Issues Summary User Impact Workaround Non-configuration file getting loaded to startup-config through HTTP. When the switch reboots and attempts to read an invalid start-up configuration file, it will give up and create a default startup configuration. It is recommended that all users keep backups of their configuration files. TACACS operation User cannot enter Privileged EXEC mode without using the enable command. None.
Summary User Impact Workaround Bridge multicast address is shown as MAC Address format in show runningconfig buffer when it is configured in IP format. If a user configures the bridge multicast address as an IP address format in VLAN interface mode, it is displayed in the show running-config command in MAC address format. None. Connected spanning tree root port role not changed to autoportfast after disabling MSTP on Trunk.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Summary User Impact Workaround ISDP updates are not including Voice VLAN Reply TLV when Voice VLAN ID on interface is changed. Upon changing configuration immediately after getting the VLAN assigned, DUT stops advertising Voice VLAN reply TLV in its ISDP updates which causes IP phone to change its VLAN properties. The administrator can work around this problem by shutting down the port and restarting it after the configuration is changed.
Known Restrictions and Limitations Layer 2 802.1AB (LLDP) Description User Impact LLDP-MED location and inventory transmit TLVs have no effect. The switch does not support configuring this data so enabling these TLVs has no effect. QoS Description User Impact Traffic permitted by an outbound ACL on one port can be allowed on another port. This behavior is a limitation of implementing egress ACLs on an ingress classifier. Given a configuration where two outbound ACLs are active on different ports.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes LACP Description User Impact LAGs Supported Number of LAGs supported: • Up to 18 Dynamic LAGs • 48 Static LAGs Limitations (stack of 12) • Long Timeouts With a minimal CPU load, it takes approximately 1.5 minutes with 16 dynamic LAGs and 15 MSTP instances for the ports to become active with traffic running. • Short Timeouts With a minimal CPU load, it takes approximately 1.
ICMP Description User Impact IPv4 Fragmentation support The switch is not fragmenting the datagram and forwards even when the IP MTU of the forwarding Interface is set to a lower value (than the datagram size). This is a hardware limitation and is working as designed. The HW does not allow the IP MTU to be configured per VLAN. We can configure the maximum frame size in HW using the 'mtu' command in interface Ethernet mode. However, if a packet exceeds the maximum frame size for a port, it is discarded.
PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Management CLI Description User Impact radius-server mode commands do not have a "no" form. None of the commands in radius-server mode support a "no" form except for the msgauth command. To reset values to the default, delete the server and add it back. SNMP Description User Impact Not able to set the value for dellLanMngInfEnable Management ACLs are always enabled and cannot be disabled.
Cable Diagnostics Description User Impact Cable Length Diagnostic shows result as 'Unknown' for a port to which Network is connected. Problem is intermittent and only observable when connected to a D-Link DES1008. File Management Description User Impact Error displayed on console while applying configuration for a 48 port switch to a 24 port switch. When applying configuration to ports which do not exist, errors are generated such that all subsequent commands fail.
