32.5 How SSH works
The following table summarizes how a secure connection is established between
two remote hosts.
Figure 160 How SSH Works
1 Host Identification
The SSH client sends a connection request to the SSH server. The server identifies
itself with a host key. The client encrypts a randomly generated session key with
the host key and server key and sends the result back to the server.
The client automatically saves any new server public keys. In subsequent
connections, the server public key is checked against the saved version on the
client computer.
2 Encryption Method
Once the identification is verified, both the client and server must agree on the
type of encryption method to use.

- Spanning tree protocol 119
- Stp rstp overview 119
- Stp terminology 119
- After a bridge determines the lowest cost spanning tree with stp it enables the root port and the ports that are the designated ports for connected lans and disables all other ports that participate in stp network packets are therefore only forwarded between enabled ports eliminating any possible network loops 120
- Allowed range 120
- Chapter 13 spanning tree protocol 120
- For each lan segment a designated bridge is selected this bridge has the lowest cost to the root among the bridges connected to the lan 120
- How stp works 120
- Link speed 120
- Mes 3528 user s guide 120
- On each bridge the root port is the port through which this bridge communicates with the root it is the port on this switch with the lowest path cost to the root the root path cost if there is no root port then this switch has been accepted as the root bridge of the spanning tree network 120
- Once a stable network topology has been established all bridges listen for hello bpdus bridge protocol data units transmitted from the root bridge if a bridge does not get a hello bpdu after a predefined interval max age the bridge assumes that the link to the root bridge is down this bridge then initiates negotiations with other bridges to reconfigure the network to re establish a valid network topology 120
- Path cost is the cost of transmitting a frame onto a lan through that port the recommended cost is assigned according to the speed of the link to which a port is attached the slower the media the higher the cost 120
- Recommended range 120
- Recommended value 120
- Stp aware switches exchange bridge protocol data units bpdus periodically when the bridged lan topology changes a new spanning tree is constructed 120
