Grant_Lee Skrevet 14. august 2008 Rapporter Del Skrevet 14. august 2008 Hei Opplever en god del undersize errors på 2 av interfacene på en Cisco 3650 switch. Dvs. tellerene går opp jevnt & trutt. Noen som vet hva dette kan komme av, og hva er Undersize errors? Det er 2 stk. Intel servers koblet på disse interfacene (Firewall-1), og de står i Trunk mode. Speed/duplex står til auto, og har forhandlet seg frem til 1000/full. Mvh. Grant_Lee Lenke til kommentar

De blir slettet av switchen(CRC eller fram for liten). Det kan komme av daarlig NIC paa sevveren, daarlig kabel, duplex-feil etc. Endret 14. august 2008 av VictorOsborn Lenke til kommentar

VictorOsborn Skrevet 14. august 2008 Rapporter Del Skrevet 14. august 2008 (endret) Det letteste er aa bytte kabel. Er ikke det problemet, kommer det sansynligvis fra FW. Fordi runts/undersize er stor sett er en receive error. For aa utelukke det helt kan du flytte konfigen din til en annen port og se om du faar samme feil. Har du mulighet aa se om det staar full duplex paa porten i FW (ASA)? Endret 14. august 2008 av VictorOsborn Lenke til kommentar

Har du mulighet aa se om det staar full duplex paa porten i FW (ASA)? Hei Det er ikke ASA, men CheckPoint Firewall-1 på HP Intel servere. Ifølge ethtool så kjører de riktig: Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: g Wake-on: d Link detected: yes Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: g Wake-on: d Link detected: yes Jeg får begynne med å bytte porter i switchen og så evt. utvidet "scopet"...

VictorOsborn Skrevet 14. august 2008 Rapporter Del Skrevet 14. august 2008 Virker som det er kabel. Crossover stoy. Slikt kan lett skje ved endene om kobberledingene er tvinnet ut for mye near rj-45 pluggen. 5mm er max. Lenke til kommentar
