Urgent Lan Dropping

stephenw10

The main System log in pfSense. I'd also check the switch log for link failure on the port.

Master crash today all network down .
So i find out that all packet on the lan where getting error in or out don’t remember ! Like million of error

I put back my intel 1000 pro
And everything look fine

So i thin’k 3 possibility is possible
Failed nic
Failed fiber
Failed transceiver

I’ll let you know in the future

Jimbohello

@stephenw10

told you ill get back to you

after more than 2-3 month, no more crash

i did change both transceiver and fiber!

but i think the issue was witthing the switch

i realise that does switch work in tandem port 49/50
51/52

i believe that the fact that a server was attach in port 49 the issue was cause by having the pfsense lan (dhcp/server) port plug into 50. so i put both server on 49/50 and add the lan fsense to 51.

crash never occur since then!

Huh? Switches don't care what ports you plug stuff into.. Sure you could have a bad port.. But sure doesn't care what you plug into ports that are next to each other ;)

@johnpoz
your absolutelly right ! but !
SINCE TECHNOLOGY INS'T ALWAYS PERFECT ! THIS SCENARIO IS POSSIBLE !

maybe it's a bug inside the swith ! inside the software or firmware or whatever !

anyway my problem is fix since 2-3 month

The 10G ports may be configured as stacking or as Ethernet in pairs. Configuring a
10G Ethernet port as stacking will also configure the paired link as stacking.
Likewise, configuring a 10G stack port as Ethernet will configure the paired link as
Ethernet. On the CE0152XB, ports 49/50 and 51/52 are paired. On the CE0128XB,
ports 25/26 and 27/28 are paired.

HAVE A NICE DAYS

So combo ports? Yeah you might wanted to mention such details off the top..

Guess should of assumed they were combo from the numbers.. But without details of the special ports your dealing with. They are not your typical common ports on a switch, which don't give 2 shits if server or whatever is next to each other.

@johnpoz
LOL
i mentionned it ! but i use the word tandem !

sorry about that confusion

i realise that does switch work in tandem port 49/50
51/52

johnpoz

Tandem is not the term have ever heard used.. Been in the business 30 some years, before there there were even switches. Never heard the term used to describe a combo port sorry..

Do a google for tandem port switch, nothing.. do a google for combo port switch.. Gazillion hits..

Tandem how would define it just means next to each other, one behind the other, etc.

@johnpoz
