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 4 - General Known Issues (Sheet 1 of 2)

Index Category Description Possible Workaround

1. Management Interfaces The CLI command

ip default-gateway

sets the gateway address to 0.0.0.0

and prevents the user from adding other gateways.

Delete the entry by using

the

no ip default-gate-

way

command.

2. In-Band Management In-band management mode does not support IPv6.

3. In-Band Management In-band management ARPs are not taken into

account in the “show ip are count” command.

4. NTP The command

show ntp

always lists the last con-

figured NTP server even if it has been deleted.

This output can be safely ignore.

5. 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.

6. 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.

7. 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.

8. Software Management Upon upgrade if there are more than 4 ACLs, all

of the ACL configuration is deleted. If there are 4

ACLs or less, rules with a sequence number larger

than 495 are deleted.

9. 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.

10. Configuration Manage-

ment

After loading a new configuration file, please

reboot the system. Otherwise, configuration might

not be properly applied.

11. Configuration Manage-

ment

Prior to license deletion make sure to be in an

allowed profile. Failing to do so results in errors.

12. Logging “DROPPED MSG” errors may appear during

reload (shutdown phase). These errors can be

safely ignored.

13. Logging The following error may appear in the log during

system de-init:

“[mdreq.ERR]: init(), mdr_main.c:634, build 1:

Error code 14014”

This error can be safely ignored.

14. 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.

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

open several browser simul-

taneously.

16. WebUI Reversing the time clock can result in WebUI

graphs’ corrupted data.

Clear the graphs data after

setting the clock.

17. WebUI Enabling/disabling HTTPS while connected via

HTTP to the WebUI may result in temporary loss

of connection to the webpage.

Refresh the page or navi-

gate back using the

browser’s back button.

18. SNMP The error “Cannot find module (MELLANOX-

MIB)” can appear in the log when performing roll-

back to a MLNX-OS version older than 3.3.3000.

This error can be safely ignored.

19. Chassis Management Supported USB flash drives are USBv2 protocol

and above.

20. IP Routing The current release does not support L3.

4.2 Ethernet Known Issues

Table 5 - Ethernet Known Issues (Sheet 1 of 3)

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. Ethernet Interfaces 40GbE passive copper cable of 5m length might

experience link rise issues when connected to

some 3rd party 40GbE interfaces.

Replace copper cable with

fiber cable

4. Ethernet Interfaces Default MTU is modified as 1500 instead of 1522.

5. Ethernet Interfaces There are no port counters for packet sizes 1518-

1522.

6. 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.

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

lished with some third party vendors.

Use a different admin-key

number.

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

tributed when testing small number of SMACs.

9. LAG When converting static LAG to dynamic LAG

(LACP), some of the ports remain in DOWN state.

Disable and enable the

LAG.

10. LAG LAG Hash function lacks configuration of a ran-

domization seed parameter. Traffic passed over

LAG in hierarchy topology via multiple SwitchX

based systems is not distributed evenly.

Change the distribution

function between layers per-

forming LAG using the

command

port-channel

load-balance

. The work-

around is applicable in case

there are multiple mixed

flows.

11. LAG When removing all ports of a port-channel and

then re-adding them to the port-channel in a differ-

ent type, port-channel may not converge.

Disable and enable the port-

channel.

12. LAG The following LACP port-states are not available

in MLNX-OS®:

• I – Individual H – hot-standby (LACP only)

• s – Suspended R – module-removed

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

delete 1000 VLANs, or to change the switchport

mode of an interface.

14. VLAN Deleting VLAN ranges on trunk/hybrid ports is

correlated to the number of the trunk/hybrid ports

in the system.

Restrict the range of

VLANs deleted to groups of

up to a 100 VLANs.

Mellanox® Technologies Confidential

Mellanox Technologies 10

15. VLAN When working with more than 2000 VLANs and

trying to change a port’s VLAN membership in

modes hybrid/trunk using the command

inter-

face 1/x switchport trunk allowed-vlan

the operation may timeout on account of it being

too heavy. Thus, the port does not become prop-

erly configured as a member of those VLANs.

Assuming port 1 is in trunk mode and there are

3000 VLANs created, a good practice would be to

achieve membership of port 1 in VLANs 100-

3000, use the command

interface ethernet

1/x switchport trunk allowed-vlan remove

1-100

instead of

interface ethernet 1/x

switchport trunk allowed-vlan 100-3000

To fix the problem, run the

commands

interface

ethernet 1/x switch-

port trunk allowed-

vlan all

and

interface

ethernet 1/x switch-

port trunk allowed-

vlan remove 1-100

succession.

16. 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.

17. IGMP Snooping Setting the

ip igmp snooping unregistered

multicast

option to

forward-to-mrouter-

ports

option reduces the amount of supported

VLANs to 250.

18. IGMP Snooping There is no possibility to have more than one

mrouter port on a single VLAN if igmp snooping

is disabled for that vlan

After enabling igmp snoop-

ing on that VLAN, the user

needs to add again the

mrouter-ports on that

VLAN.

19. LLDP LLDP notifications are not supported.

20. LLDP The mgmt0, mgmt1 IPv6 addresses and the in-

band management address are not advertised on

LLDP TLV(s).

21. ACLs A mask of IPv4 ACL rule can contain either 255

or 0 in any of the 4 bytes assembling it.

22. ACLs Packets dropped by the switch due to congestion

or ACL rules are added to the bad type counter of

the matching VLAN interface.

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

005), wrong data is displayed under transceiver

information.

24. Modules Using 1GbE copper modules leads to the port sta-

tus being constantly reported as active regardless

from the actual link state.
