1、准备工作
首先先看下目前的license
# show activation-key Serial Number: JMX1J364741 Running Permanent Activation Key: 0xc......................................e2ae Licensed features for this platform: Maximum Physical Interfaces : 8 perpetual VLANs : 3 DMZ Restricted Dual ISPs : Disabled perpetual VLAN Trunk Ports : 0 perpetual Inside Hosts : 50 perpetual Failover : Disabled perpetual Encryption-DES : Enabled perpetual Encryption-3DES-AES : Enabled perpetual AnyConnect Premium Peers : 2 perpetual AnyConnect Essentials : Disabled perpetual Other VPN Peers : 10 perpetual Total VPN Peers : 12 perpetual Shared License : Disabled perpetual AnyConnect for Mobile : Disabled perpetual AnyConnect for Cisco VPN Phone : Disabled perpetual Advanced Endpoint Assessment : Disabled perpetual UC Phone Proxy Sessions : 2 perpetual Total UC Proxy Sessions : 2 perpetual Botnet Traffic Filter : Disabled perpetual Intercompany Media Engine : Disabled perpetual Cluster : Disabled perpetual This platform has a Base license. The flash permanent activation key is the SAME as the running permanent key.
2、升级
输入更新的license
# conf t
(config)# activation-key 0x4......................................480
有可能会有这个提示，不知道为什么，不用理会
直到输入，说是请求的key和在缓存中的是一样的，也就是说已经将新的key写入了缓存
看下show activation-key，说缓存中的key和现在运行的key不一致
3、重启
保存wr，重启reload
再看activation-key
4、问题
一开始有log不停的输出，可以使用no logging console关闭
