SG350XG - %SYSLOG-F-OSFATAL: caught segmentation fault - BONJOUR task

[carnyx.io]

Hello,

I havec several switches SG350XG-2F10.

Since i activated the "BONJOUR" protocol to connect switches to Cisco Business Dashboard, i regularly have emergency errors :    %SYSLOG-F-OSFATAL: caught segmentation fault exception 

%SYSLOG-F-OSFATAL: caught segmentation fault exception at address 0xaa4ff6f5 signal-num = 11 (SIGSEGV) signal-code = 2 (SEGV_ACCERR) reg[00] = 0xaa4fc3f3 reg[01] = 0xaa4fc356 reg[02] = 0x0 reg[03] = 0x9f reg[04] = 0x339f reg[05] = 0xaa4fc406 reg[06] = 0x50e688e4 reg[07] = 0x50e689dc reg[08] = 0x0 reg[09 ] = 0x50e688e3 reg[10] = 0x50e688dd FP = 0x0 IP = 0xf3 SP = 0x50e68798 LR = 0xc1d3ec PC = 0xc1a518 CPSR = 0xa0030010 Fault Address = 0xaa4ff6f5 Trap no = 0xe Err Code = 0x17 Old Mask = 0x0 ***** FATAL ERROR ***** Reporting Task: BNJR. Software Version: 2.5.9.54 (date Nov 29 2023 time 14:36:03) base_ad

My firmware is the last one i think : 2.5.9.54

What can i do to connect my switches to CBD without BONJOUR errors ?

Best regards

Looks like a bug https://bst.cisco.com/quickview/bug/CSCvo48821 - but i dont see a fix?

hello and thanks

My switches have 2.5.9.54 firmware and it's not a SNMP fault but BONJOUR protocol fault.

So it's not really similar

  - @carnyx.io               It remains a bug , if you are on latest firmware involve cisco :
                                                                 https://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html

 - @carnyx.io  This bug report : https://bst.cisco.com/bugsearch/bug/CSCvo48821?rfs=qvlogin has  a Fixed status. But Known Fixed releases is empty. That means that developers have resolved the issue , but ir is not yet incorporated in a production release. Contact Cisco's TAC to ger an ETA on that ,

Thanks Mark but this product has exceeded Last Day of Support date (2025-06-30). Apparently I can't contact support on this EOL range of switches...

Do you know, if i can connect my SG350XG switches to Cisco Business Dashboard without BONJOUR protocol ?

Perhaps with SNMP or CDP ?

Oh, how I miss Cisco Network Assistant on the old C2960G and C3560X switches. It worked better and with more features than CBD..

                           That looks like a yes : Ref  https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/cisco-business-dashboard/admin-guide/b_Cisco_Business_Dashboard_Admin/b_CBD_chapter_00.html
                         >....In a direct managed network, you will need to connect the first device to the Cisco Business Dashboard manually. Then, this device reports information such as CDP, LLDP, and mDNS (aka Bonjour) to Dashboard. This information is used to identify additional devices in the network,

Indeed, I could connect only one switch per site, and let the others be discovered via CDP. This would undoubtedly limit the number of switches affected by crashes. But it's still a last resort...

I also tried activating the CBD probe on one of the switches, but the results weren't conclusive.

I'll dig a little deeper, but it's not very serious of Cisco to offer unfinished solutions.

They remove CNA, which was very good, and replace it with CBD, which is worthless.

I'm a long-time user, and I find that the quality of Cisco products has deteriorated significantly over time

  - @carnyx.io   I can agree with those observations but these devices are long EOL and now also past support:
