Connectrix MDS: KERN-3-SYSTEM_MSG Porta di riferimento errore checksum GBIC-SFP

Connectrix MDS9148S o 9148T che esegue 8.4(2a) o 8.4(2f) con SFP (Small Form-factor Pluggable) di terze parti non supportato potrebbe segnalare errori di checksum Gigabit Interface Converter (GBIC) - SFP.

Questo problema è documentato nel problema Cisco CSCvz21847.

Le interfacce Fibre Channel (FC) su cui non è installato un modulo SFP Cisco FC non vengono visualizzate.
Lo switch segnala:

%PORT-3-IF_UNSUPPORTED_TRANSCEIVER: Transceiver for interface fcx/y is not supported.

Potrebbero anche essere visualizzati messaggi del kernel relativi agli errori di checksum GBIC-SFP.

%KERN-3-SYSTEM_MSG: [4121386.701907] GBIC/SFP checksum error ref port:30 - kernel

La porta a cui si fa riferimento nel messaggio del kernel si basa sul conteggio a partire da zero, quindi una cifra in meno rispetto al messaggio di errore PORT.

Sostituire il modulo SFP non supportato con un modulo SFP supportato da Cisco ufficiale.
