3.2.17 SSH
SSH mainly provides a secure login passage for the administrative user. The device
provides SSH server function for the user logs in as client. Client and server will negotiate
about the encrypted key before they establish the connection, with which server and
client can encrypt and de-encrypt the packet they send to each other to make the packet
unidentifiable by others during the process of transmission.
3.2.18 Port loopback check
Port loopback check works to separate the network. The device will block the port when it
finds loopback in the downlinked network of the port to avoid the influence on the whole
network of the loopback. Port loopback check can work only with the support of a single
node without the same protocol run in the whole network. ZXR10 5250 supports single
port and multi-port loopback check.
