网络维护时间- Cisco & Juniper

Question

我维护Cisco & Juniper设备，最近开发人员抱怨路由器升级需要太长时间。因为我们还没有高可用性。我该怎么缩短停工时间？

我现在做的是：

(Juniper)
root> request system software add ftp://10.10.70.2/jinstall-ex-2200-12.3R9.4-domestic-signed.tgz 

[Sep 19 21:49:31]: Checking pending install on fpc0
Fetching package...


(Cisco)
2911#copy ftp://admin:123456@10.10.10.3/c2900-universalk9-mz.SPA.154-3.M2.bin flash
Destination filename [c2900-universalk9-mz.SPA.154-3.M2.bin]? 
Accessing ftp://*****:*****@10.10.10.3/c2900-universalk9-mz.SPA.154-3.M2.bin...!

Answer 1

对Juniper来说

root> request system software add no-copy no-validate ftp://10.10.70.2/jinstall-ex-2200-12.3R9.4-domestic-signed.tgz 

添加no-copy和no-validate以缩短验证时间

对西斯科来说

Router#copy ? 
/erase Erase destination file system. 
/error Allow to copy error file. 
/noverify Don't verify image signature before reload.

启用/noverify
