SFPを挿します。
Apr 17 10:23:15.793 JST: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi1/0/1 has bad crc
Apr 17 10:23:15.793 JST: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/0/1, putting Gi1/0/1 in err-disable state
と怒られます。インタフェースも落ちます。
cat3750#show int status | i err
Gi1/0/1 err-disabled 1 auto auto unknown
直し方。
cat3750#configure terminal
cat3750(config)#no errdisable detect cause gbic-invalid
cat3750(config)#service unsupported-transceiver
Warning: When Cisco determines that a fault or defect can be traced to
the use of third-party transceivers installed by a customer or reseller,
then, at Cisco's discretion, Cisco may withhold support under warranty or
a Cisco support program. In the course of providing support for a Cisco
networking product Cisco may require that the end user install Cisco
transceivers if Cisco determines that removing third-party parts will
assist Cisco in diagnosing the cause of a support issue.
cat3750(config)#^Z
抜き差しします。あとはshutdown/no shutdownも。
Apr 17 11:02:58.929 JST: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi1/0/2 has bad crc
Apr 17 11:02:58.929 JST: %PHY-4-UNSUPPORTED_TRANSCEIVER: Unsupported transceiver found in Gi1/0/2
ニュアンスが変わります。情報も見れます。そしてupします。
cat3750#sh idprom interface gigabitEthernet1/0/1

cat4948ではno errdisable detect cause sfp-config-mismatchなんてconfigを見たりしたけど、ほかにもいろいろありそうなきもします。
