问题描述

Brocade光纤操作系统下载命令失败、并显示消息：

[SULB-1011],113,SLOT 6 CHASSIS,INFO,DCX8510,Firmwaredownload command failed. Failed to download firmware signature..

Command firmwaredownloadstatus 出现以下故障：

firmwaredownloadstatus: [1]: Sat Feb 13 20:06:46 2021 Slot 6 (CP0, active): Firmware is being downloaded to standby CP. This step may take up to 30 minutes. [2]: Sat Feb 13 20:06:49 2021 Slot 6 (CP0, active): Firmware download failed on standby CP - Failed to download firmware signature. (0x40)

在交换机和关闭TCP流的SCP或FTP服务器之间安装了防火墙或安全系统
firmwaredownload 命令中使用的路径指向firmware.gz文件。
要检查CP和Chassis的子网、请使用命令 ipaddrshow

ipaddrshow: CHASSIS Ethernet IP Address: XXX.XXX.XXX.49 Ethernet Subnetmask: 255.255.0.0 CP0 Ethernet IP Address: XXX.XXX.XXX.50 Ethernet Subnetmask: 255.255.255.0 Host Name: cp0 Gateway IP Address: none CP1 Ethernet IP Address: XXX.XXX.XXX.51 Ethernet Subnetmask: 255.255.255.0
