Jeg har 2 Cisco 3524-PWR XL switche der er forbundet med Gigabit fiber plugins. Med jævne mellemrum forsvinder forbindelsen meget kortvarigt mellem de 2 switche. F.eks. bliver brugere logget af msn, Teamspeak og internetsurfing står stille et par sekunder. Jeg har desværre ikke mulighed for at teste med almindelige utpkabler. Nogen der har en ide om hvad der kan være galt?
For at få lidt detaljer på fejlen, så installer en syslog server på en computer. Jeg bruger selv KiWi Syslog: http://www.kiwisyslog.com/software_downloads.htm#syslog Så går du ombord i switchene, gå i Global Config og tast kommandoen "logging <IP adresse>" og "wr" - hvor du angiver din syslog maskines IP (det er selvfølgelig smartest hvis det er en maskine med fast IP :-) Så er det bare om at kikke hvad den siger, når problemet opstår. Smid evt interface konfigurationen hér i forum'et.
Tak for tippet. Det vil jeg straks prøve på mandag når jeg kommer på arbejde igen. Er det via telnet man skal give de komandoer eller kan jeg bruge http interface?
Det er nemmest at bruge telnet, web interfjæset er muligvis disable og for øvrigt ikke særligt rart at have med at gøre. Alternativt via konsolporten med et serialkabel.
Her er så lidt screendump fra syslog. Ved ikke om det siger noget:

Det er de almindelige switch porte der melder UPDOWN når en maskine slukkes/tændes. Det er dine GigabitEthernet porte der er interessante, men de fortæller ikke noget hér. Når du oplever problemet, sp klip loggen ud for det tidsrum.
