Mozilla Firefox to view the certificate. If you cannot connect to the switch using HTTPS and the web
portal displays a message of invalid certificate, that is an indication that the certificate on the switch
is expired. You can replace the host.cert and host.key files with new files generated off the switch,
or you can use the procedure
Managing an SSL certificate on page 169 to generate a new
certificate on the switch with a specific validity period.
The default certificate key length for a certificate generated on the switch is 2,048 bits.
SSH rekeying
SSH rekeying is an SSHv2 feature that allows the SSH server/client to force a key exchange
between server and client, changing the encryption and integrity keys. Once you enable SSH
rekeying, key exchanges occur after a pre-determined time interval or after the data transmitted in
the session reaches the data-limit threshold.
SSH rekeying occurs when either the time-interval or data-limit value is met. The default time-
interval is 1 hour and the default data-limit is 1 GB. These values are configurable using the ssh
rekey command.
SSH rekey is optional. You can enable SSH rekey only when global SSH is enabled. Most SSH
clients and servers do not provide a rekey mechanism; in that case, you should not enable SSH
rekey. Active sessions shut down if the rekey fails.

clients and servers do not provide a rekey mechanism, do not enable SSH rekey in such cases.
Note:
You cannot enable SSH rekey selectively for either SSH client or server, it is enabled both on
the SSH client and server together.
Secure Shell configuration using ACLI
Use Secure Shell version 2 (SSHv2) to enable secure communications support over a network for
authentication, encryption, and network Integrity.
On IPv6 networks, the VSP switch supports SSHv2 server only. The VSP switch does not support
outbound SSHv2 client over IPv6. On IPv4 networks, the VSP switch supports both SSHv2 server
and SSHv2 client.
