1. Login:
2. Mount USB:
For EX:
mount -t msdosfs /dev/da1s1 /mnt
mount_msdosfs /dev/da1s1 /mnt
For QFX:
mount -t msdosfs /dev/da0s1 /mnt
3. Copy firmware to local drive:
For EX:
cp /mnt/jinstall-ex-4300-17.3R3-S4.2-signed.tgz /var/tmp
For QFX
cp /mnt/jinstall-host-qfx-5-17.3R3-S4.2-signed.tgz /var/tmp
4. Unmount USB:
umount /mnt
5. Install new firmware and reboot
For EX:
cli
request system software add /var/tmp/jinstall-ex-4300-17.3R3-S4.2-signed.tgz no-copy no-validate reboot
For QFX:
cli
request system software add /var/tmp/jinstall-host-qfx-5-17.3R3-S4.2-signed.tgz no-copy no-validate force-host reboot

接下来需要恢复出厂设置
使用常规的恢复出厂命令（request system zeroize）会发现在此版本下该命令使用有问题
（无法清空配置）
（使用request system zeroize恢复出厂会自动重启系统）
root> request system zeroize
warning: System will be rebooted and may not boot without configuration
Erase all data, including configuration and log files?. In case of Dual RE system, both Routing Engines will be zeroized [yes,no] (no) yes
warning: zeroizing fpc0
error: Failed to clear nvram. (status 256)
接下来，换一个恢复出厂命令（load factory-default）
（使用load factory-default恢复出厂不会自动重启系统，所以后面还需要手工重启）
root@pvg03-sfi-mdf3-2r20> configure
root@pvg03-sfi-mdf3-2r20# load factory-default

可以看到，直接指定文件夹中的bin文件作为BOOT path-list，重启后bin版本并没有成功升级
以往是成功了
这次，把bin文件从文件夹中拿出来试一下

至此，版本升级完成
为什么要先copy到sd卡中进行引导，引导成功后再将新版本copy到flash？
首先，flash中有旧版本，在内存不够的情况下需要删除旧版本，使用新版本，但是有可能新版本引导时会有问题，如果贸然删除旧版本，可能会造成死机，所以先在sd卡中进行新版本引导，如果说引导正常没问题，才可以确定这个新版本是OK的
其次，有时候可能sd卡会出现问题，所以当sd卡中的新版本引导成功后，可以把新版本放入flash卡中，这样，当sd卡故障，系统就会自动查找flash卡，找到新bin文件
注系统引导，先找sd卡，再找flash卡
IE 2000 din upgrade

升级前为ie2000-universalk9-mz.152-7.E3.bin
升级后为ie2000-universalk9-mz.152-8.E1.bin

后来发现，之所以ae0接口的up的，而链路状态是down的，是因为这条链路上还没有任何流量通行
完成trunk封装即可

网络基础环境搭建完成
接下来模拟堆叠备设备出故障，需要用备机来进行设备更换操作
设备更换操作按照以下步骤严格执行：
- 更换设备需提前检查设备版本，确保替换设备正确（4400-48P：21.1R3-S4.2，4300-48P:18.4R2-S7.4）
- 替换设备前后确保网线接入配线架的顺序不变；若有飞线的情况，检查跳线端口所属的vlan，在不影响生产的情况下修改端口vlan配置恢复跳线按顺序插入配线架；
- 更换设备前需提前抓取mac地址表信息，与更换后的mac地址表进行对比；
- 在替换设备后的mac中随机选取3-5个mac地址，上防火墙查看arp获取ip地址信息，ping测试；
- 更换后检查网络可达性，确保能远程ssh进行管理；
实现
1、在开始时，四台交换机版本都为4400-48P：21.1R3-S4.2
2、本实验中，不涉及配线架
在实际项目中，往往配线架和交换机端口的一一对应的，如果说存在交换机和配线架交叉互连的情况，在不影响生产的情况下，可以把这两个交叉端口的配置互换，从而在连线上实现一对一
3、更换设备前抓取mac地址表信息
root# run show ethernet-switching table
MAC flags (S - static MAC, D - dynamic MAC, L - locally learned, P - Persistent static, C - Control MAC
SE - statistics enabled, NM - non configured MAC, R - remote PE MAC, O - ovsdb MAC)
Ethernet switching table : 3 entries, 3 learned
Routing instance : default-switch
Vlan MAC MAC Age Logical NH RTR
name address flags interface Index ID
default f8:c1:16:47:4c:80 D - ae0.0 0 0
vlan82 c0:14:fe:ca:1b:c1 D - ge-1/0/10.0 0 0

Vlan MAC MAC Age Logical NH RTR
name address flags interface Index ID
vlan82 c0:14:fe:ca:1b:c1 D - ge-1/0/10.0 0 0

之所以要排除从聚合口学习到的mac地址，是因为聚合口是上连口，并且作为trunk连接，放行所以vlan，所以从聚合口可以学习到很多mac地址，甚至是其他不相干设备的mac地址
而我们关心的是本故障设备下连的上网终端更换后是否可以成功上线，所以我们只需要看下连接口学习到的mac就行
接下来，堆叠备设备出现故障，无法使用
我们首先需要把备设备上的堆叠线缆拔掉
由于是在堆叠环境中，新设备又是一个空配，所以我们只需要在主设备上重新指定member 1为备机就行了
（因为故障设备就是member 1）

堆叠备设备故障，下架，备机上线成功
把故障设备上插的线移插到备机上（互连光纤和下连设备）
更换设备后抓取mac地址表信息
root# run show ethernet-switching table | except ae0
MAC flags (S - static MAC, D - dynamic MAC, L - locally learned, P - Persistent static, C - Control MAC

可以看到，mac地址表前后是一致的
4、在替换设备后的mac中随机选取3-5个mac地址，上防火墙（三层设备）查看arp获取ip地址信息，ping测试
root# run show arp
MAC Address Address Name Interface Flags
c0:14:fe:ca:1b:c1 192.168.82.1 192.168.82.1 irb.82 [ae0.0] none

用下连设备去ping网关，通
Switch(config)#do ping 192.168.82.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.82.254, timeout is 2 seconds:
