4 Known Issues

The following table describes MLNX-OS™ known issues in this software release and possible

workarounds.

4.1 General Known Issues

For any possible errata due to hardware issues, please refer to the switch support prod-

uct page.

Table 3 - General Known Issues (Sheet 1 of 2)

Index Category Description Possible Workaround

1. Management Interfaces Host name may not include the “.” character.

Modules When using 5m splitter cable (P/N MC2609125-

005), wrong data will be displayed under trans-

ceiver information. It can be safely ignored.

3. NTP Deleting an NTP entry and enabling it back may

result in a wrong “show ntp” output (unsynchro-

nized). This can be safely ignored.

4. Software Management Only one image is allowed to be copied into the

system (using the

image fetch command). The

user must remove old image files prior to fetching

a new one.

5. Software Management Upgrading to v3.2.0594 (or later) forces all Con-

nectX®-3 adapters that are connected to this

switch to upgrade their firmware to adapter firm-

ware v2.10.7204 (or later). For switch-to-switch

connections, it is highly recommended that all

SwitchX® switches be upgraded to MLNX-OS

version v3.2.0594 (or later) to guarantee robust

interoperability.

6. Software Management In case of an upgrade, ACL sequence-number “0”

is not valid any more. In case there are two ACL

entries with sequence number of “0” and “1”

(sequential entries), the ACL with sequence-num-

ber 0 is deleted. In other cases where there is an

ACL entry with sequence-number “0”, it is moved

to be sequence-number 1 within the system

upgrade procedure.

In case you have an ACL

entry with sequence

number “0”, recreate it

with different sequence

number, prior to the

upgrade procedure.

7. Configuration Manage-

ment

Loading the wrong system configuration file may

hang the system.

For example: an attempt to use an SX1016 config-

uration file on an SX6036/SX6536/SX1035 sys-

tem may cause the system to hang.

4.2 Ethernet Known Issues

Table 4 - Ethernet Known Issues

8. Configuration Manage-

ment

After loading a new configuration file, please

reboot the system. Otherwise, configuration might

not be properly applied.

9. Configuration Manage-

ment

The command

configuration revert fac-

tory

is removed.

Use the command reset fac-

tory instead.

10. Logging “DROPPED MSG” errors may appear during

reload (shutdown phase). These errors can be

safely ignored.

11. User Management Some RADIUS and TACACS+ configurations

keep the user locked out of the machine due to

timeout limitation.

Press the reset button for 15

seconds, and then log in

using your local authentica-

tion. Additionally, fix the

configuration to avoid any

future timeout issues.

12. User Management Restoring admin password is not supported.

13. CLI The feature “Ctrl+C” is not supported in this

release.

It is advised to avoid using

it.

14. WebUI Only a single WebUI login per host is possible. To have multi-sessions,

open several browser simul-

taneously.

15. WebUI Reversing the time clock can result in WebUI

graphs’ corrupted data.

Clear the graphs data after

setting the clock.

16. SNMP LLDP MIB OID lldpRemPortDesc is not sup-

ported.

17. Chassis Management Supported USB flash drives are USBv2 protocol

and above.

18. Chassis Management Duplicate notification is sent upon high tempera-

ture alerts, both specific module alerts and general

“too high” alerts.

19. IP Routing The current release doesn’t support L3.

Index Category Description Possible Workaround

1. Ethernet Interfaces The system allows tolerance of 4 bytes on top of

the set MTU.

2. Ethernet Interfaces In case of faulty cable, rise time of other interfaces

in the system may be delayed.

3. LAG Convergence time of port removal from a LAG

exceeds the specification by up to 30 seconds.

Shut down the port prior of

removing it from the LAG.

Table 3 - General Known Issues (Sheet 2 of 2)

Index Category Description Possible Workaround

Mellanox Technologies

4. LAG The remote LACP admin-key #1 cannot be estab-

lished with some third party vendors.

Use a different admin-key

number.

5. LAG Traffic running over LAG may not be evenly dis-

tributed when testing small number of SMACs.

6. LAG A port-channel stops forwarding traffic after dis-

abling some Ethernet ports in the same port-chan-

nel group.

Disable and enable the

LAG.

7. LAG When converting static LAG to dynamic LAG

(LACP), some of the ports remain in ‘DOWN’

state.

Disable and enable the

LAG.

8. VLAN It might take approximately 20 seconds to create/

delete 1000 VLANs, or to change the switchport

mode of an interface.

9. Spanning Tree Non-standard behavior may occur on third party

switch STP functionality when the port moves

from Root to Alternate state. The standard Pro-

posal-Agreement sent by MLNX-OS is unan-

swered which may result in traffic loss of up to 30

seconds.

10. IGMP Snooping Setting the “ip igmp snooping unregistered multi-

cast” option to “forward-to-mrouter-ports” option

reduces the amount of supported VLANs to 250.

11. ACL A mask of IPv4 ACL rule can contain either 255

or 0 in any of the 4 bytes assembling it.

12. ACL ACL is not supported on split interfaces.

13. ACL Removing configured ACL on split interfaces

requires reset factory.

5 Bug Fixes

The following table describes MLNX-OS™ bug fixes in this software release.

Table 5 - Bug Fixes (Sheet 1 of 2)

Index Category Description

1. Ethernet Interfaces When trying to give a description to a port after it has been split, the command

fails.

Ethernet Interfaces After reload, port flow control might appear enabled when it is actually disabled.

3. Ethernet Interfaces On rare occasions the internal links does not come up in 40GbE.

4. Spanning Tree While running the show spanning-tree command, the error

“issd_st_get_switch_port_loop_guard - nmhGetFsMIMstCistPortLoopGuard

failed with issin-dex” might appear in the log. This can safely be ignored.

5. LLDP User cannot delete all optional LLDP TLVs (only modifying them), one of the

optional LLDP TLVs will be added always.

6. QoS Mapping user priority ‘i’ (0<= i <=7) to traffic class 0 (TC0), while priority based

flow control (PFC) is enabled on priority ‘i’, may cause excessive transmission of

pause frames in case of congestion.

7. User Interfaces ME allows 1Gb/s speed option in CLI and WebUI.

8. CLI Make behavior consistent between “banner login” in CLI and WebUI equivalent.

9. Chassis Management ME firmware version information does not display within OA interfaces.

10. WebUI Clicking the “Apply” button in the port configuration section might cause a port

restart.

11. SNMP The entity-sensor MIB is currently not supported.

12. System MLNX-OS shows the model type of ME as “SX689638” when it is actually

“SX1018HP”.

13. LLDP LLDP uses only mgmt0 IP address as management address.

14. LLDP When changing the mgmt0 IP address or port description, LLDP does not update

this information in the LLDP TLVs.

15. LLDP LLDP notifications are not supported.

16. LLDP By default, the management address is not advertised in the LLDP management

address TLV.

17. LLDP A TLV management address is sent for all IP interfaces in the system.

18. LLDP When an interface is disabled, an LLDPDU with TTL 0 is not sent.

19. LLDP Chassis ID is advertized via the system GUID.

20. LLDP LLDPDUs with the wrong EtherType are not discarded.

21. LLDP The SwitchX management address is not advertised on splitter ports.

22. ACL There is no enforcement for configuring out-of-range VLAN in ACL.

Mellanox Techologies

23. ACL When splitting an Ethernet interface with an ACL rule, the interface remains

bound by the ACL.

24. ACL MAC packets are discarded when the IPv4 ACL deny rule is defined.

25. Logging SDKd process errors may appear during reload (shutdown phase) or switching

system profile.
