Renewing DCHP
DHCP may lease addresses to clients indefinitely or for a specific period of
time. If the address expires or the switch is moved to another network
segment, you will lose management access to the switch. In this case,
reboot the switch or submit a client request to restart DHCP service.
Web Interface
If the address assigned by DHCP is no longer functioning, you will not be
able to renew the IP settings via the Web Interface. You can only restart
DHCP service via the Web Interface if the current address is still available.
Command Line Interface
Enter the following command to restart DHCP service.
Security
Configuring the Login Password
The guest only has read access for most configuration parameters.
However, the administrator has write access for parameters governing the
onboard agent. You should therefore assign a password as soon as
possible, and store it in a safe place.
Notes: 1.
If you log into the Web interface as guest (Normal Exec level),
you can view page information but only change the guest
password. If you log in as admin (Privileged Exec level), you
can apply changes on all pages.
2.
If your password is lost, contact your local supplier for
assistance.
The default guest name is “guest” with the password “guest.” The default
administrator name is “admin” with the password “admin.” Note that user
names can only be assigned via the CLI.
