学员提问：
在看asa的配置文档关于透明模式时，看到关于management ip address的一段话
A transparent firewall does not participate in IP routing. The only IP configuration required for the adaptive security appliance is to set the management IP address. This address is required because the adaptive security appliance uses this address as the source address for traffic originating on the adaptive security appliance, such as system messages or communications with AAA servers. You can also use this address for remote management access.
For multiple context mode, set the management IP address within each context. To set the management IP address, enter the following command:
hostname(config)# ip address ip_address [mask] [standby ip_address]
This address must be on the same subnet as the upstream and downstream routers. You cannot set the subnet to a host subnet (255.255.255.255)”
最后一句话You cannot set the subnet to a host subnet (255.255.255.255)是什么意思？
