more information, see the appendix “Monitoring and Analyzing Switch Operation” in the Management and

Configuration Guide for your switch, and the chapter “Configuring and Monitoring Port Security” in the Access Security Guide for your switch.

Version KA.15.10.0003

MIB to Check Load of Module Slots

■ Enhancement (PR_0000073100, CR_0000077888) - This feature provides SNMP read access to the CPU

utilization of the modules. Currently the only method to retrieve the module CPU utilization is the CLI command show cpu slot <slot | all>. A new MIB table is created to facilitate the reading of information related to the module and its CPU utilization statistics.

AAA Authorization on HTTPS

■ Enhancement (CR_0000103497) - When using Commands authorization, the Web Agent windows may show or

hide fields, or allow or deny configuration steps, based on the access or deny list (VSA filtering) for the authenticated user. For more information, see the chapter "RADIUS Authentication, Authorization, and Accounting" in the Access Security Guide for your switch.

IPv6 DNS via RA Options

■ Enhancement (CR_0000107183) - IPv6 Router Advertisements allow IPv6 routers to advertise a list of recursive

DNS Server (RDNSS) addresses and a DNS Search List (DNSSL) to IPv6 hosts. The new command options are ipv6 nd suppress-ra-dns, which is executed in the global config context, and ipv6 nd ra suppress-dns, which is executed in the VLAN context. For more information, see the chapter "IPv6 Router Advertisements" in the IPv6 Configuration Guide for your switch.

Reinterpret CDP Info When Using IP Phones

■ Enhancement (CR_0000108063) - Prevents MAC addresses from being learned on the specified ports when the

VLAN is untagged and the destination MAC address is 01000c-CCCCCC (CDP), 0180c2-00000e (LLDP), or 0180c2000003 (EAPOL). The feature is configured per-port by using the ignore-untagged-mac <port-list> command. For more information, see the chapter "Configuring for Network Management" in the Management and Configuration Guide for your switch.

Page 15

Secure Mode

■ Enhancement (CR_0000108494) - Secure Mode is now supported on the HP 3800 switches. Secure Mode allows

the transition between standard secure mode and enhanced secure mode for several security functions. Standard secure mode is the existing, default security mode on the switch. Enhanced secure mode provides an additional level of switch security. For more information, see the chapter "Secure Mode" in the Access Security Guide for your switch.

OpenFlow

■ Enhancement (CR_0000109154) - OpenFlow is a programmable open-standard network protocol that uses flexible

matching rules to classify and manage network traffic into flows. For more information, see the OpenFlow Configuration Guide.

Comware CLI Commands in ProVision Software (Phase 3)

■ Enhancement (CR_0000115963) - This is the third of four phases that allows a Comware CLI proficient user to

use their Comware CLI knowledge to effectively manage and configure ProVision software switches. This phase adds 97 additional Comware display commands to the ProVision software CLI. With this addition there are now 230 Comware display commands in the ProVision software CLI.

ROM Updates Required!

BootROM updates are needed to be able to boot specified switch software versions. In most cases, selected software versions are used to automatically update the BootROM.

This software includes an update to BootROM KA.15.09. If your switch has an older version of BootROM, the BootROM will be updated with this KA.15.10.0022 software. During the software update, the switch will automatically boot twice, first to update the BootROM to the proper version, and then to load the system software. After the switch flash memory is updated and the final boot is initiated, no additional user intervention is needed. Do not interrupt power to the switch during this

important update.

Installation Instructions

The Basic Operation Guide for your switch provides software installation and management information on the following topics:

■ downloading switch documentation and software from the Web

■ saving configurations while using the CLI

■ best practices for software updates

To access the guide, visit the HP Networking manuals web page. (Refer to “Description” on page 3.)

Issues and Suggested Actions

RADIUS Server Authentication Issue

Because of an inconsistency between the Windows XP 802.1x supplicant timeout value and the switch default timeout value, which is 5, when adding a backup RADIUS server, set the radius-server timeout value to 4 on the switch. Otherwise, the switch may not failover properly to the backup RADIUS server.

Fixes

Software fixes are listed in chronological order, from oldest to newest software version. Unless otherwise noted, each new software version includes all the software fixes added in previous versions.

KA.15.03.3004 was the initial software version for the HP 3800 switches.

Version KA.15.03.3005

Status: Released and fully supported, but not posted on the Web. The following problems were resolved in software version KA.15.03.3005.

■ CLI (PR_0000072869, CR_0000077695) - The switch does not allow the use of a dash or an underscore ("-" or "_")

in an unauth-redirect URL.

■ Crash (PR_0000072341, CR_0000077244) - With a client connected to a port configured for MAC-based

authentication and unauth-redirect, if that client fails authentication the switch might reboot unexpectedly with a message similar to the following.

Software exception at hwBp.c:211 -- in 'fault_handler', task ID = 0xaa3d1c0

■ Crash (PR_0000103369, CR_0000103369) - A switch configured with the command web-management ssl might

reboot unexpectedly with a message similar to the following.

Software exception at http_init.c:543 -- in 'tHttpd', task ID = 0xa984d80

■ Port Crash (PR_0000103236, CR_0000103236) - Although rare, a group of ports on the 48-port switch might

reboot unexpectedly. The ports will not recover until the switch is rebooted. The affected ports are 1-24 and 49-50. The event log will display a message similar to the following.

chassis: ST2-CMDR: Ports 1/1-24,49-50 crash detected

■ Stacking (PR_0000072434, CR_0000077325) - With a stack connected as a ring, when one of the stack members

is rebooting the stack allows the user to reboot a different member, which can fragment the stack.

Version KA.15.03.3006

Status: Released and fully supported, and posted on the Web. The following problems were resolved in software version KA.15.03.3006.

■ CLI (PR_0000070114, CR_0000075294) - The switch gives an error message when the user adds a port to an

existing voice VLAN. Also, a VLAN already configured with a tagged port cannot later be configured as a voice VLAN.

■ CLI (PR_0000071092, CR_0000076119) - Multiple voice VLANs are no longer allowed. With this fix, multiple voice

VLANs are allowed again.

■ Crash (PR_0000072472, CR_0000077356) - In some situations the switch might reboot unexpectedly with a

message similar to the following.

Crash msg: Invalid Instr HW Addr=0x00000000 IP=0x0 Task='mSess2' Task ID=0xa91a700 sp:0x6446788 lr:0x12c4824 msr: 0x02029200 xer: 0x20000000 cr: 0x48000400

Page 18

Version KA.15.03.3007

Status: Released and fully supported, but not posted on the Web. The following problem was resolved in software version KA.15.03.3007.

■ CLI (CR_0000108615) - The output of the show tech all command stops after the show interfaces section.

Version KA.15.03.3008

Status: Released and fully supported, but not posted on the Web. The following problem was resolved in software version KA.15.03.3008.

■ Event Log (CR_0000110967) - The switch calculates internal parity errors incorrectly, which causes event log

messages similar to parity recovery 1553 0x80000c0a.

Version KA.15.03.3009

Status: Never released. The following problems were resolved in software version KA.15.03.3009.

■ Crash (CR_0000107764) - With VRRP enabled, a switch might crash again during bootup after a crash.

■ Event Log (CR_0000110723) - The error message: IpAddrMgr: STI-CMDR: FAILED - Module 3\ BMP

TCAM, parity recovery 0x80000000 0x00000000 appears in the event log.

■ Management (CR_0000106958) - After multiple TELNET and SSH sessions are opened and then closed in rapid

succession, the switch might not allow a new management connection to open even though there are available sessions, responding with the error message: Sorry, the maximum number of sessions are active. Try again later.

■ Stacking (CR_0000111105) - The output of show tech does not include information about stack members.

■ Stacking (CR_0000111563) - The output of show tech does not include adequate information about the stacking

link between stack members.

■ Switch Hang (CR_0000109565) - The switch might fail to boot fully, requiring a power-cycle to recover.

Version KA.15.03.3010

Status: Released and fully supported, but not posted on the Web. The following problem was resolved in software version KA.15.03.3010.

■ Switch Hang (CR_0000112490) - The switch becomes unresponsive during output of the show tech all command.

Output halts after issuing the stackingshowtech command on a Member.

Page 19

Version KA.15.03.3011

Status: Never released. The following problems were resolved in software version KA.15.03.3011.

■ EEE (CR_0000110739) - Energy Efficient Ethernet (EEE) is enabled by default on HP 3800 switches with software

versions KA.15.03.3010 and earlier. On early hardware versions of the 3800 switches, 1-Gigabit Ethernet ports toggle offline/online intermittently when connected to a device that also has EEE enabled due to a problem with a rev. A0 PHY chip. (This PHY hardware issue is now resolved with a version A1 PHY on the 3800 switch.) With this software fix, a switch that has version A0 PHYs will have EEE disabled permanently, and a switch that has version A1 PHYs will have EEE disabled by default. If desired, the user can enable EEE on switches with A1 PHYs.

■ Switch Hang (CR_0000112490b) - The switch becomes unresponsive during output of the show tech all command.

Output halts after issuing the stackingshowtech command on a Member. This improves the original CR_0000112490 fix documented in KA.15.03.3010.

Version KA.15.03.3012

Status: Released and fully supported, but not posted on the Web. No problems were resolved in software version KA.15.03.3012.

Version KA.15.03.3013

Status: Never released. The following problems were resolved in software version KA.15.03.3013.

■ Config (PR_0000069007, CR_0000074368) - After downloading from a TFTP server,theoobm keyword is removed

from a config file that has an sntp server command with the oobm parameter.

■ Crash (PR_0000073144, CR_0000077919) - During processing of the show tech all command, if event log messages

are being received at a very high rate, the switch might reboot unexpectedly with a message similar to the following:

NMI event SW:IP=0x00000000 MSR:0x00000000 LR:0x00000000 cr:0x00000000 sp:0x00000000 xer:0x00000000 Task=’mSess2’ Task ID-0x3c8ae000

■ Self Test (CR_0000113055) - The switch might report a self test port failure after rebooting, on ports with active

devices. This affects ports that are connected at 100 Mbps. Workarounds: either unplug and then reconnect the network cable, or disable and then enable the port.

■ Stacking (CR_0000111533) - When the Commander is powered off or fails over, SFP ports on the Standby lose

link and do not recover. This only affects SFP ports (not SFP+ ports), so this is only an issue when the Standby is a J9584A HP 3800-24SFP-2SFP+Switch.

■ Switch Hang (CR_0000113858) - After issuing the redundancy switchover command from a TELNET or SSH session,

the Standby hangs with all LEDs on. Workaround: press and hold the Reset button on the hung switch for 5 seconds, then release.

■ Switch Hang (CR_0000114060) - After issuing the boot system command, the switch hangs with all LEDs on.

Workaround: press and hold the Reset button on the hung switch for 5 seconds, then release.

Page 20

Version KA.15.03.3014

Status: Never released. The following problems were resolved in software version KA.15.03.3014.

■ Crash (CR_0000114460) - After issuing the redundancy switchover command, the switch might reboot unexpectedly

with a message similar to the following:

NMI event SW:IP=0x00000000 MSR:0x00000000 LR:0x00000000 cr:0x00000000 sp:0x00000000 xer:0x00000000 Task=’mSess3’ Task ID-0x3c8ad000

■ Port Communication (CR_0000114387) - The switch ports might connect at 10 Mbps full-duplex instead of Gigabit

full-duplex. This issue only affects switches with the letters DL and DM in the middle of the serial number (for example, SG21DM9876).

Version KA.15.03.3015

Status: Released and fully supported, and posted on the Web. The following problem was resolved in software version KA.15.03.3015.

■ Switch Hang (CR_0000114699) - The CLI command copy command-output ‘show tech all’ tftp causes the switch to

become unresponsive.

Version KA.15.09.0003

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.09.0003.

■ BootROM (CR_0000108445) - This software version includes a BootROM update to BootROM version KA.15.06.

■ Config (CR_0000104888) - The IPv6 nd ra prefix command requires configuration of valid lifetime and preferred

lifetime values before the user can add the parameters off-link and no-autoconfig. If the configured lifetime settings are the default values (valid = 2592000 and preferred = 604800), the off-link and no-autoconfig parameters are not listed in the config file. When the switch is rebooted, the parameters function properly even though they are not listed in the config file. However, if the config file is saved to a TFTP server, then loaded onto a switch, the configuration will not operate as expected because the parameters are missing.

■ Crash (CR_0000108146) - After a large amount of querier elections the switch might reboot unexpectedly with a

message similar to the following.

NMI event SW:IP=0x001ce064 MSR:0x02029200 LR:0x001ce064 cr: 0x28000400 sp:0x0478b5f0 xer:0x00000000 Task='mIgmpCtrl' Task ID=0xa94a000

■ DHCP (CR_0000113976) - DHCP addresses are not properly assigned when Web Authentication or MAC

Authentication clients fail authentication and are redirected at a high rate.

■ DHCP Snooping (CR_0000108666) - When a PXE protocol DHCP-offer packet is sent from a boot server through

a trusted port, the switch drops the packet.

■ Distributed Trunking (CR_0000106804) - With Distributed Trunking enabled and a large number of MAC

addresses learned by the switch (on the order of several thousand addresses), the switch experiences a gradual loss of free memory.

■ Port Communication (CR_0000114548) - When port 14 is configured for tagged packets only, untagged packets

including STP BPDUs are not received by that port. Workaround: configure an untagged VLAN on port 14.

Page 21

■ VRRP (CR_0000113863) - After a reboot, the VRRP Master configured with a preempt delay timer sends a gratuitous

ARP from the switch's physical MAC address instead of the VRRP virtual MAC address. This causes routing to fail until the preempt delay timer expires.

Version KA.15.09.0004

Status: Released, but removed from the web due to CR_0000124276. This software is recalled and no longer recommended.

■ CLI (CR_0000115515) - The switch does not allow configuration changes via the CLI, responding with the error

message inconsistent value. This has been observed when the configuration includes snmpv3 targetaddress TARGETADDRESS with a TARGETADDRESS string longer than 24 characters.

■ Config (CR_0000117518) - A switch configured with a username and password and with include-credentials cannot

be accessed after updating software, because the username is wrongly removed from the config file during the software update.

■ Crash (CR_0000115929) - With very large key sizes, the command show crypto host-cert might cause the switch to

reboot unexpectedly with a message similar to the following.

Invalid Instr HW Addr=0x00000000 IP=0x0 Task='mSess2' Task ID=0xa97ad40 sp:0x4acecc8 lr:0x57e468 msr: 0x02029200 xer: 0x20000000 cr: 0x28000400

■ Crash (CR_0000116647) - It is possible for the switch to reboot unexpectedly with a message similar to the

following.

Software exception in kernel context at ghsException.c:1101

-> Internal system error

■ Module Crash (CR_0000113992) - In a rare situation, a switch module or port bank might reboot unexpectedly

with a message similar to the following.

chassis: Slot H Read Error Restr Mem Access HW Addr=0xffaaaaf0 IP=0x1a10d64 Task='mIpAdMUpCt' Task ID=0x1b1e2300 Bus Error Data=0x00000000 Status=0x00000400

■ Module Crash (CR_0000116226) - In a rare situation, a switch module or port bank might reboot unexpectedly

with a message similar to the following. This improves the original Module Crash fix (CR_0000113992), also in KA.15.09.0004.

chassis: Slot H Read Error Restr Mem Access HW Addr=0xe5911000 IP=0x1a10da8 Task='mIpAdMUpCt' Task ID=0x1b1e4c80 Bus Error Data=0x00000000 Status=0x00000400

■ Power (CR_0000112424) - When the switch is exposed to AC power fluctuations and the voltage drops too low,

the switch reboots and generates an incorrect error message saying the switch crashed. With this fix, the error message is changed to Switch rebooting due to temporary loss of power or low voltage.

■ SSL (CR_0000115933) - Under certain conditions, the VLAN -> VLAN Mgmt page on the switch cannot be accessed

via an SSL connection to the web user interface.

■ Web Management (CR_0000108339) - The switch's web user interface cannot be accessed via the fully-qualified

domain name in some situations. Workaround: Use the IP address to access the switch's web user interface.

Page 22

Version KA.15.10.0003

Status: Released, but removed from the web due to CR_0000124276. This software is recalled and no longer recommended.

■ BootROM (CR_0000119469) - This software version includes a BootROM update to BootROM version KA.15.09.

■ Crash (CR_0000114674) - A stack member might reboot unexpectedly with a message similar to the following,

after the user enters the command show tech stacking member X where X is not the commander number.

Restr Mem Access HW Addr=0xfee81fb0 IP=0xa2f26b8 Task='muiCtrl' Task ID=0x3c939780 sp:0x125aa2a0 lr:0xa2f2358 msr: 0x02029200 xer: 0x00000000 cr: 0x24000800

■ Crash (CR_0000116647) - It is possible for the switch to reboot unexpectedly with a message similar to the

following.

Software exception in kernel context at ghsException.c:1101

-> Internal system error

■ Crash (CR_0000116912) - With OSPF routing and MSTP enabled, it is possible for the switch to reboot unexpectedly

with a message similar to the following.

Software exception at rt_table.c:4453 -- in 'eRouteCtrl', task ID = 0xa95e140

-> Routing Stack: Assert Failed

■ Crash (CR_0000118474) - The switch experiences a gradual loss of free memory when clients that use a RADIUS-

assigned ACL reauthenticate. This can cause the switch to reboot unexpectedly.

■ Distributed Trunking (CR_0000103240) - With Distributed Trunking enabled, applying the command clear mac-

address to the VLAN of the InterSwitch-Connect (ISC) on one switch can cause the peer switch to drop packets that

should be forwarded across the ISC.

■ Distributed Trunking (CR_0000115557) - Multicast hosts might be temporarily dropped from the multicast

stream, in a topology with Distributed Trunking where a Group-Specific Host Membership Query should be forwarded across the Inter-Switch Connection (ISC).

■ Distributed Trunking (CR_0000118526) - In a switch-to-switch Distributed Trunkingtopologywith IGMP enabled,

multicast streams learned on one Distributed Trunking switch might not be known to the other Distributed Trunking switch. The result is multicast streams that cannot be joined by clients on one switch.

■ Distributed Trunking (CR_0000118663) - The standby switch periodically reports Out of pkt buffers,on

a stack with redundant management configured for Distributed Trunking. This can lead to an unexpected reboot of the standby switch.

■ Enhancement (PR_0000073100, CR_0000077888) - This feature provides SNMP read access to the CPU

■ Enhancement (CR_0000103497) - When using Commands authorization, the Web Agent windows may show or

Page 23

■ Enhancement (CR_0000107183) - IPv6 Router Advertisements allow IPv6 routers to advertise a list of recursive

■ Enhancement (CR_0000108063) - Prevents MAC addresses from being learned on the specified ports when the

■ Enhancement (CR_0000108494) - Secure Mode is now supported on the HP 3800 switches. Secure Mode allows

■ Enhancement (CR_0000109154) - OpenFlow is a programmable open-standard network protocol that uses flexible

matching rules to classify and manage network traffic into flows. For more information, see the OpenFlow Configuration Guide.

■ Enhancement (CR_0000115963) - This is the third of four phases that allows a Comware CLI proficient user to

■ File Transfer (CR_0000106249) - A configuration file that has loop protection enabled on a trunk cannot be

downloaded to the switch, if the trunk does not exist in the currently-running configuration.

■ Module Crash (CR_0000110845) - With MSTP enabled on the switch, a port configured for MAC authentication

and loop protection does not detect a loop on a downstream switch. This can lead to CPU utilization of 90-100%, and the switch module or port bank might reboot unexpectedly with a message similar to the following.

Software exception in ISR at ngDmaRx.c:1660

■ Module Crash (CR_0000116784) - If a MAC address moves between three Distributed Trunks repeatedly, the

switch modules or port banks where the MAC address is seen experience a gradual loss of free memory that can lead to a module or port bank crash.

■ OSPF (CR_0000117192) - When an OSPF neighbor is in the INIT state and the router receives a one way hello from

that neighbor, the event log generates a message that the switch received an invalid one way hello. OSPF routing functions properly but this message should not be generated. This fix removes that erroneous message.

■ sFlow (CR_0000110640) - When sFlow sends a sample that was routed, the switch does not have information to

display the port on which the packet was received. With this fix, the sFlow sample will show zero as the received interface index instead of 0x3fffffff.

■ Switch Hang (CR_0000114815) - If any of the parameters in the command snmpv3 targetaddress includes a space,

when the config is saved and the switch is rebooted the switch will hang and fail to boot fully.

■ Web Management (CR_0000108339) - The switch's web user interface cannot be accessed via the fully-qualified

domain name in some situations. Workaround: Use the IP address to access the switch's web user interface.

Version KA.15.10.0004

Status: Never released. No problems were resolved in software version KA.15.10.0004.

Page 24

Version KA.15.10.0005

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0005.

■ ACLs (CR_0000119956) - Removing an ACL entry (ACE) that is a comment (a "remark") causes undesired changes

to the ACL.

■ BGP (CR_0000122109) - When configuring a BGP neighbor, the switch does not accept IP addresses that would be

broadcast or network addresses in a classful addressing scheme. For example, the switch does not allow the neighbor addresses 15.255.255.255 or 15.0.0.0.

■ CLI (CR_0000115033) - With stacking disabled and SSH file transfer enabled, the switch does not allow the user

to "copy" the crash-data, crash-log, or coredump files via SFTP.

■ Counters (CR_0000119114) - The output of the show system temperature command gives incorrect values.

■ Display Issue (CR_0000121028) - Some MAC addresses are displayed incorrectly in the output of CLI commands

show lldp info remote-device and display lldp neighbor-information list.

■ Routing (CR_0000120907) - A switch that has a default gateway or less-specific route configured does not allow

users to connect to the switch's IP loopback address. The packets are routed instead of being accepted by the switch.

■ SNMP (CR_0000120223) - The Entity MIB lists the stacking module as available hardware even if no stacking

module is inserted in the switch.

■ TFTP (CR_0000119184) - The switch experiences a loss of free memory each time command output is copied to

a TFTP server. When memory is no longer available, the TFTP will fail with a message similar to

TFTP download in progress. Failed to allocate a new TFTP client. 00000K Request failed.

Version KA.15.10.0006

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0006.

■ 802.1X (CR_0000122837) - Clients have issues with authentication when 802.1X and MAC Authentication are both

configured on a port.

■ Crash (CR_0000117378) - When a stack member crashes, that member might reboot continuously instead of

rejoining the stack.

■ Distributed Trunking (CR_0000120627) - Some traffic is lost when a member of a Distributed Trunk pair is

rebooted.

■ IPv6 (CR_0000122825) - IPv6 packets with a mask of /65 to /127 are routed to the default route instead of the

intended destination.

■ PIM-DM (CR_0000122264) - Some PIM-DM multicast streams fail when a default route is configured on the switch.

■ Spanning Tree (CR_0000110052) - In a topology with multiple MSTP regions and multiple same-cost links

connecting the regions, the CST root port might change to a CST alternate port, and MSTP instances might be blocked on region boundary ports.

■ SSH (CR_0000122795) - SSH session disconnects when the SSH key re-exchange takes place.

■ Switch Hang (CR_0000124001) - In a 3800 stack with CDP passthrough configured, the standby will hang when

the commander goes down.

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0007.

■ Authentication (CR_0000122439) - With multiple certificates installed on the switch, PEAP-MSCHAPv2

authentication fails when using Windows Server 2008 R2 Network Policy Server (NPS).

■ Crash (CR_0000122225) - The switch might reboot unexpectedly when using VRRP with a message similar to

Software exception in ISR at btmDmaApi.c:378.

■ Crash (CR_0000124443) - Rarely, when ports go offline, then back online while voice VLAN requests are being

sent, the switch might reboot unexpectedly with a message similar to Software exception at sw_sem.c:1036 -- in 'mSnmpCtrl' -> Deadlock found!.

■ IGMP (CR_0000105902) - IGMPv2 LEAVE processing functionality no longer works for a multicast group after

receipt of IGMPv1 group specific membership query (GSMQ) packet when operating in IGMPv2 mode, even when ip igmp forcedfastleave 1-24 is enabled.

■ SNMP (CR_0000124187) - With stacking enabled, the time-stamps in SNMP traps do not match sysUptime on the

switch.

■ SNMP (CR_0000124375) - A switch configured to send syslog messages to a server also sends incorrect SNMP

traps, causing unknown trap messages in the syslog server.

■ TFTP (CR_0000124276) - The switch experiences a loss of free memory each time the CLI command copy running-

config tftp is issued by a user or by a network management platform. When memory is depleted on the commander,

the switch will respond to CLI commands such as show run with the error message Translator Failed. In that state, stack configuration changes might cause 3800 stack members to reboot repeatedly with a message similar to Reboot of Member ID 2, RFS Error reboot.

Version KA.15.10.0008

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0008.

■ Authentication (CR_0000114307) - The switch does not allow users to login when the configured authentication

method is peap-mschapv2.

■ Crash (CR_0000126636) - It is possible for the switch to reboot unexpectedly, under conditions of very high traffic

volumes and high CPU utilization.

Version KA.15.10.0009

Status: Released and fully supported, and posted on the web. The following problems were resolved in software version KA.15.10.0009.

■ ACLs (CR_0000122535) - When configuring an ipv4 or ipv6 prefix-list, it is not possible to add an entry to permit/

deny 'any'.

■ CLI (CR_0000125980) - After configuring debug ip pbr, the output of show debug does not include pbr in the list of

enabled debug types.

■ CLI (CR_0000127335) - Using the CLI command show tech all can cause the system to reboot unexpectedly.

■ Crash (CR_0000120116) - With OSPF configured, in a rare situation the switch might reboot unexpectedly with a

message similar to

Software exception at rt_table.c:4453 -- in 'eRouteCtrl', task ID = 0xa9c4c00 -> Routing Stack: Assert Failed.

Page 26

■ Crash (CR_0000126799) - Under unusual stress conditions, the switch might reboot unexpectedly with a message

similar to

Software exception at fileTransfer.c:1144 -- in 'tHttpd', task ID = 0xa9389c0 -> Could not open file.

■ DHCP Snooping (CR_0000126311) - The CLI entry dhcp-snooping option 82 untrusted-policy keep is not included in

the config file if no dhcp-snooping option 82 is also configured. If the config file is saved to a TFTP server, it will not function properly when subsequently loaded on a switch.

■ Distributed Trunking (CR_0000124473) - The switch does not allow DHCP server responses to cross the Inter-

Switch Connection (ISC).

■ Distributed Trunking (CR_0000125623) - After rebooting a switch participating in a distributed LACP trunk, a

distributed trunk port that is disconnected will not link after it is connected.

■ Distributed Trunking (CR_0000127096) - When the Inter-Switch Connection (ISC) is brought down, clients

connected via Distributed Trunk links cannot be reached from one of the Distributed Trunking switches.

■ Include Credentials (CR_0000127700) - With include credentials enabled, a config file that is saved to a TFTP

server does not contain the SNMPv3 credentials.

■ LEDs (CR_0000115489) - After a PoE error is resolved, the switch turns off the PoE LED but continues to flash the

Fault LED.

■ OSPF (CR_0000122980) - OSPF3 ECMP routes are not displayed in the IPv6 route table.

■ Policy Based Routing (CR_0000125847) - After configuring a policy and applying it to a VLAN, the IP next-hop is

unreachable until the switch is rebooted.

■ Routing (CR_0000123230) - The switch does not forward traffic to a host that has a static route configured with a

32-bit subnet mask. Traces show that the switch never sends an ARP request for that host.

■ Routing (CR_0000128007) - ARP replies from a Microsoft Network Load Balancing (NLB) cluster operating in

multicast mode cause the switch to use software routing. This affects v2 zl modules and 3800 switches.

■ sFlow (CR_0000128567) - The switch uses the IP address of the source VLAN as the sFlow packet source, instead

of the configured source-interface.

■ SNMP (CR_0000122623) - After rebooting a switch configured for SNMP with the parameters operator unrestricted,

the switch does not allow the user to set any read/write MIB objects.

■ SNMP (CR_0000125513) - The value stored in MIB object ospfNbrState (OID 1.3.6.1.2.1.14.10.1.6) is incorrect.

■ Transceivers (CR_0000126801) - After booting a 3800 switch or a K-software switch with a v2 zl module, a J9054B/

C 100-FX SFP-LC transceiver that was already inserted (or is inserted during the boot process) will not link with the remote end.

■ Web Management (CR_0000125239) - After logging into the switch Web user interface, closing the tab on some

Web browsers does not log the user out of the Web session.

Version KA.15.10.0010

Status: Released, but no longer recommended due to CR_0000127868. The following problems were resolved in software version KA.15.10.0010.

■ IGMP (CR_0000127628) - In a topology where the host connects to a querier, the querier connects to a non-querier

switch, the non-querier switch connects to a router, and the multicast source is beyond the router, the host might not receive the multicast stream. This happens because a "join" from the host that is received by the querier is not forwarded by the non-querier switch.

Page 27

■ IGMP (CR_0000127974) - If a switch receives a PIM packet while it is in the querier election state, the switch gives

up the querier role and does not forward multicast traffic.

Version KA.15.10.0011

Status: Released and fully supported, but not posted on the web. The following problem was resolved in software version KA.15.10.0011.

■ Uplink Failure Detection (CR_0000127868) - On a switch that is configured for uplink failure detection where

the link to monitor (LtM) or link to disable (LtD) is an LACP trunk, after reboot the link to monitor is listed as down in the output of show uplink-failure-detection, and the link to disable is taken down by the switch.

Version KA.15.10.0012

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0012.

■ Config (CR_0000127108) - After downgrading from a newer software version to a 15.10 software version, the output

of show run lists an incorrect software build version in the Created on release statement.

■ Config (CR_0000129797) - A config file that has the entry ipv6 ospf3 passive on a tunnel cannot be downloaded to

the switch.

■ GVRP (CR_0000129917) - When the switch receives its own GVRP frames, it learns from them instead of dropping

the frames.

■ GVRP (CR_0000130090) - After rebooting the switch, the configuration unknown-vlans disable does not work on

trunks.

■ Link (CR_0000128466) - After booting a switch with a port configured for 100-full, if that port is changed to 10-half

it will not link with a remote device that runs at 10-half.

■ QoS (CR_0000123663) - VRRP IPv4 DSCP is tagged as 0 and cannot be changed by remarking.

Version KA.15.10.0013

Status: Never released. The following problems were resolved in software version KA.15.10.0013.

■ Crash (CR_0000126777) - With a combination of interface state changes along with IPV6 address configuration

changes, it is possible for the switch to reboot unexpectedly with a message similar to SubSystem 0 went down:

01/24/13 13:31:29, Invalid Instr HW Addr=0x000004a8 IP=0x4a8, Task='mIpCtrl' Task ID=0xa9ca140 sp:0x470aab0 lr:0x723f4c, msr: 0x02029200 xer: 0x20000000 cr: 0x48000400.

■ Dynamic ARP Protection (CR_0000132073) - When a VLAN is configured for dynamic ARP protection and also

DHCP snooping, ARP packets should be forwarded but are incorrectly dropped when the arp-protect configuration does not include the validate ip option.

■ Loop Protection (CR_0000127150) - Loop protection fails to detect a loop on a port configured for 802.1X

authentication, if 802.1X is not enabled globally.

■ PIM (CR_0000128681) - After a large number of multicast streams are added and old streams time out, the switch

might get into a state where it is unable to add new multicast streams, responding with a message similar to IpAddrMgr: Failed to allocate new SW IP multicast group, table full FIB entry.

Version KA.15.10.0014

Status: Never released. The following problems were resolved in software version KA.15.10.0014.

Page 28

■ Banner MOTD (CR_0000132198) - The login banner is not displayed if the user logs into the switch via the standby

or member switch instead of the active or commander switch.

■ CLI (CR_0000128124) - The output of show monitor and show monitor <mirror_destination_number> displays

information for only mirror destination #1.

■ Crash (CR_0000127791) - With OSPF configured, in a rare situation the switch might reboot unexpectedly with a

message similar to Software exception at rt_table.c:4453 -- in 'eRouteCtrl', task ID = 0xa9c4c00 -> Routing Stack: Assert Failed. This improves the original Crash fix (CR_0000120116).

■ Distributed Trunking (CR_0000132286) - When a MAC address moves from a Distributed Trunk port to a non-

Distributed-Trunk port, the switch MAC tables sometimes show that MAC address on the wrong port.

■ Distributed Trunking (CR_0000132900) - With a switch configured for both Distributed Trunking and MSTP, a

MAC address learned on a VLAN that is not part of the Inter-Switch Connection (ISC) might not appear in the MAC table, or might appear on the wrong port. This issue has been observed when all the Distributed Trunk ports are down on the switch that learns the MAC address.

■ Distributed Trunking (CR_0000133318) - Distributed trunk links might go down after a redundancy failover of

an 8200zl switch running in Nonstop Switching mode.

■ Event Log (CR_0000127436) - After the switch uptime reaches 497 days, the timestamp entries in the event log

become erratic with gaps of several hours or days. In some cases the timestamps revert to previous months and years, even though SNTP updates with those wrong timestamps report the correct date and time.

■ Management (CR_0000134091) - Disabling write access to an SNMP community via the Web user interface might

cause the switch to become unresponsive to command input. The switch must be rebooted to regain management access.

■ MSTP (CR_0000129044) - In a high-availability environment, ports might be incorrectly blocked by STP.

■ OpenFlow (CR_0000134471) - OpenFlow flows are not programmed correctly when RPVST+ is disabled on the

OpenFlow member VLAN.

■ Passwords (CR_0000130921) - If the switch is configured with a username and password, changing the password

causes the username to also change. The username is changed to the default "manager" or "operator", depending on which password is changed.

■ Passwords (CR_0000134675) - The switch does not automatically create a default username of "manager" or

"operator" when a password is configured for those levels of access.

■ PIM (CR_0000130353) - The switch might send duplicate multicast packets when sFlow is enabled and the multicast

packets are routed by software.

■ SNMP (CR_0000123582) - Including the detail parameter in the command show ipv6 ospf3 link-state area-scope detail

might cause infinite output. This affects the show tech all command, which includes the detail parameter.

■ SSL (CR_0000133153) - If the SSL option is enabled, and an external EWA server is configured, the switch

incorrectly uses an https (secure) redirect page when accessing a plain text URL.

■ TFTP (CR_0000129475) - A switch config that has certain lines in the config file cannot be downloaded to the

switch via TFTP. For example, attempting to download a config file with the valid statement distributed-trunking peer- keepalive udp-port 6400 results in the error message UDP port 6400 is already in use.

■ Transceivers (CR_0000132781) - Software does not allow the dual-speed J8177C Gigabit-copper transceiver to be

configured for 100 Mbps operation, responding with a message such as Value auto-100 is not applicable to port A21.

■ Transceivers (CR_0000133023) - 100-Megabit transceivers might have one or more of these symptoms: 1) Link

LED is lit but link is down, 2) No Link after the transceiver is hot-swapped, 3) Transceiver fails self test.

Version KA.15.10.0015

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0015.

■ Config (CR_0000135481) - After boot, a config file that has a trap destination community name with an open

parenthesis "(" or a close parenthesis ")" cannot be downloaded to the switch.

■ Distributed Trunking (CR_0000135388) - When a MAC address moves from a Distributed Trunk port to a non-

Distributed-Trunk port, the switch MAC tables sometimes show that MAC address on the wrong port. This fix improves the original Distributed Trunking fix (CR_0000132286).

Version KA.15.10.0016

Status: Released and fully supported, and posted on the web. The following problems were resolved in software version KA.15.10.0016.

■ IGMP (CR_0000132149) - Although the RFC requires that the switch with the lowest IP address becomes querier,

a switch that is acting as querier stops being querier when it receives a query from a switch with a higher IP address.

■ IGMP (CR_0000135527) - A non-querier switch that receives a Join from the querier fails to send further Joins to

the querier, resulting in loss of multicast traffic.

■ IGMP (CR_0000136013) - After the switch becomes querier, it does not update the table that defines the querier

port, and continues to forward IGMP packets out the port that previously led to the querier.

■ Web Management (CR_0000135883) - The "Rx Errors" column is missing from the Web user interface.

Version KA.15.10.0017

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0017.

■ CLI (CR_0000137287) - The output of show run vlan <VLAN_ID> omits the no in the configuration entry no ip igmp

fastleave. Note that the output of show run gives correct information.

■ Config (CR_0000129574) - After upgrading from 15.09 to 15.10 or 15.11 software, the RADIUS server key is

incorrectly removed from the configuration.

■ Distributed Trunking (CR_0000135353) - With Distributed Trunking and VRRP enabled, when both the VRRP

master and backup routers reboot together, the VRRP master might not be reachable by the Distributed Trunking switches.

■ IGMP (CR_0000135527) - A non-querier switch that receives a Join from the querier fails to send further Joins to

the querier, resulting in loss of multicast traffic.

■ LLDP (CR_0000132891) - When an IP phone is connected directly to the switch, the output of the command show

lldp info remote-device gives an incorrect value for the phone's IP address.

■ MAC Authentication (CR_0000129991) - MAC Authentication fails when the peap-mschapv2 parameteris included

in the aaa authentication CLI command.

■ OSPF (CR_0000123661) - OSPFv3 packets do not include the differentiated services information that should be in

the Traffic Class field of the IPv6 header.

■ OSPF (CR_0000135171) - Using the Menu interface, if the user navigates to Switch Configuration -> IP

Configuration and selects Save without changing anything on that screen, any OSPF configuration will be removed from every VLAN.

Page 30

■ PIM-SM (CR_0000135871) - In some cases, a "join" from a remote host is not properly processed by the switch and

the multicast traffic is not forwarded. This has been observed after a host on the same subnet as the multicast source has joined the stream, and a remote host leaves the multicast stream.

■ sFlow (CR_0000128439) - When an sFlow-sampled inbound packet is to be routed, the sFlow data gives the wrong

output port on the switch.

Version KA.15.10.0018

Status: Released, but this software is recalled and no longer recommended due to CR_0000115372. No problems were resolved in software version KA.15.10.0018.

Version KA.15.10.0019

Status: Released and fully supported, but not posted on the web. The following problem was resolved in software version KA.15.10.0019.

■ Crash (CR_0000115372) - The switch might reboot unexpectedly with a message similar to NMI event

SW:IP=0x00000000 MSR:0x00000000 LR:0x00000000 cr: 0x00000000 sp:0x00000000 xer:0x00000000 Task='InetServer' Task ID=0xaad3000.

Version KA.15.10.0020

Status: Released and fully supported, but not posted on the web. The following problems were resolved in software version KA.15.10.0020.

■ IGMP (CR_0000138408) - Joins sent by clients in response to a Group Specific Query are not forwarded by the

Querier, causing the clients to lose the stream.

■ Multicast (CR_0000138817) - When a multicast stream is sent to a reserved multicast address, a General Query

might not be not forwarded by the switch, causing clients to be dropped from the multicast stream.

Version KA.15.10.0021

Status: Released and fully supported, but not posted on the web. The following problem was resolved in software version KA.15.10.0021.

■ IGMP (CR_0000140514) - After disabling IGMP forwarding on a port, multicast traffic incorrectly continues to flow

from that port.

Version KA.15.10.0022

Status: Released and fully supported, and posted on the web. The following problems were resolved in software version KA.15.10.0022.

■ Accounting (CR_0000133762) - If a Windows system is configured for both computer authentication and user

authentication, accounting might not function properly.

■ Config (CR_0000138447) - After a switch software update, SNMP community access privileges are incorrectly

changed by the switch. The output of show snmp-server and the output of a "walkmib" command give different results, and neither output represents how the switch actually behaves for Manager or Operator access. This issue was introduced with CR_0000122623; if the access settings were configured on a switch without the CR_0000122623 fix, after updating to software with the CR_0000122623 fix the settings are changed.

■ Crash (CR_0000135900) - In some situations it is possible for the switch to reboot unexpectedly with a message

similar to Software exception at alloc_free.c:646 -- in 'eDrvPoll', task ID = 0xa9a7a80

-> buf already freed by 0x0A9A7D40, op=0x0006003E.

Page 31

■ Crash (CR_0000138879) - After boot, a switch that has a syslog server and an IPv6 address configured might become

unresponsive to management, and after a period of time the switch might reboot repeatedly with a message similar to NMI event SW:IP=0x001517d4 MSR:0x02029200 LR:0x0015178c cr: 0x28000400 sp:0x03aae0e0

xer:0x00000000 Task='mDebugCtrl' Task ID=0xa9f8000.

■ DHCP (CR_0000137877) - A switch acting as a DHCP relay agent sends two DHCP packets, one of which incorrectly

has the source MAC address of the client instead of the switch.

■ ICMP (CR_0000134682) - The switch does not log an unsolicited ICMP reply unless it has first pinged some (any)

IP address. Also, unsolicited ICMP reply log messages are sometimes associated with the DEFAULT_VLAN instead of the VLAN of the incoming unsolicited ICMP reply.

■ Jumbo Frames (CR_0000137961) - When jumbo frames are enabled on any VLAN, OSPF fails to establish an

adjacency after a switch reboot, and RIP updates might not be accepted by the router.

■ Jumbo Frames (CR_0000141474) - When jumbo frames are enabled on any VLAN, OSPF fails to establish an

adjacency after a switch reboot, and RIP updates might not be accepted by the router. This fix improves the original Jumbo Frames fix (CR_0000137961).

■ Mirroring (CR_0000134191) - IP connectivity to the mirror endpoint switch might be intermittent when remote

mirroring is configured on the management VLAN, and mirroring is configured for traffic in both directions.

■ OSPF (CR_0000137616) - When the switch is configured as an OSPF neighbor, and the neighbor changes time,

OSPF adjacency will temporarily drop.

■ PIM (CR_0000134883) - High CPU utilization from PIM message exchanges causes dropped multicast streams.

■ sFlow (CR_0000134427) - sFlow sampling of multicast packets sometimes results in duplicate packets that can

cause pixelation of video or other degradation of the multicast stream.

■ TFTP (CR_0000132721) - Certain lines in the configuration file are sometimes incorrectly changed when imported

via TFTP. For example, the configuration entry snmp-server community public unrestricted might have the unrestricted parameter removed when the config file is downloaded via TFTP.
