4.12.5 SSH
Configure SSH on this Page. This Page shows the Port Security status. Port Security is a module with no direct configuration.
Configuration comes indirectly from other modules - the user modules. When a user module has enabled port security on a port,
the port is set-up for software-based learning. In this mode, frames from unknown MAC addresses are passed on to the port
security module, which in turn asks all user modules whether to allow this new MAC address to forward or block it. For a MAC
address to be set in the forwarding state, all enabled user modules must unanimously agree on allowing the MAC address to
forward. If only one chooses to block it, it will be blocked until that user module decides otherwise.
The status Page is divided into two sections - one with a legend of user modules and one with the actual port status. The SSH
Configuration screen in Figure 4-12-5 appears.
