本ドキュメントは Catalyst 9400 で基本的な各種トラブルシューティングで はじめに確認するコマンド群を紹介します。
トラブルシューティングは事象に対して一回のコマンド群の採取で、全てを網羅することは不可能であり、Step by Step で事象の詳細化、絞り込み化が重要です。
一回のコマンド採取のみしか許可されないというユーザ様は、本番環境とは別環境で再現性の確立の上、コマンド採取頂くことが有効です。

Inject: CP generated protocol packet sent to DP to egress out on IO interface(s).
例:
Cat9400#show platform software fed active inject cpuq all Inject CPU Q Statistics =========================================== CPU Q Id : 0 CPU Q Name : TX_CPUQ_PRIO_LOW Packets received from IOSd : 766 Enq to pkt driver total attempts : 0 Enq to pkt driver failed count : 0 Count of TX CMPL received : 0 TX suspend count : 0 TX unsuspend count : 0
Punt: Ingress protocol control packet which intercepted by DP sent to the CP to process it.
Dumps all the packets sent to the different CPU queues and possible drops.
Example:
Cat9400#show platform software fed active punt cpuq all Punt CPU Q Statistics =========================================== CPU Q Id : 0 CPU Q Name : CPU_Q_DOT1X_AUTH Packets received from ASIC : 0 Send to IOSd total attempts : 0 Send to IOSd failed count : 0 RX suspend count : 0
