Console#
After your initial login, define new passwords for both default user names to prevent unauthorized access to the switch, and record the passwords for future
reference.
1. At the CLI login prompt, enter admin as the user name and password for the Privileged Exec level. Press <Enter>.
2. Type configure and press <Enter>.

3. To set the Normal Exec level password, type username guest password 0 password, where password is your new password (up to eight characters).
Press <Enter>.
4. To set the Privileged Exec level password, type username admin password 0 password, where password is your new password (up to eight characters).
Press <Enter>.
5. To save your configuration changes, type copy running-config startup-config and then press <Enter>.

SNMP Settings
Simple Network Management Protocol (SNMP) is a protocol designed specifically for managing devices on a network. Network equipment, such as hubs,
switches, and routers, use SNMP to configure system features for proper operation, as well as to monitor their performance and detect potential problems.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects)
is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a
standard presentation of the information controlled by the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this
information over the network.
The PowerConnect 5212 switch includes an on-board SNMP agent that monitors the status of the switch hardware, as well as the traffic passing through the
ports. A computer on the network running SNMP-based management software, called a Network Management Station (NMS), can be used to access this
information. Access rights to the SNMP agent are controlled by community strings. To communicate with the switch, the NMS must first submit a valid
community string for authentication.
The default community strings for the switch are:
l Public — Allows authorized management stations to retrieve MIB objects.
l Private — Allows authorized management stations to retrieve and modify MIB objects.
If you do not intend to utilize SNMP, delete both of the default community strings. SNMP management access to the switch is disabled if no community strings
exist. To delete the strings:
1. If you are not already in the Privileged Exec level global configuration mode, type configure and press <Enter>.
2. To delete the private community string, type no snmp-server community private and then press <Enter>.
3. To delete the public community string, type no snmp-server community public and then press <Enter>.
4. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
If you do intend to utilize SNMP, change the default community strings to prevent unauthorized access to the switch:
1. If you are not already in the Privileged Exec level global configuration mode, type configure and press <Enter>.
2. To delete the existing private community string, type no snmp-server community private and then press <Enter>.
3. Type snmp-server community string rw, where string is your new community string (case sensitive) for read-write access. Press <Enter>.
4. To delete the existing public community string, type no snmp-server community public and then press <Enter>
5. Type snmp-server community string ro, where string is your new community string (case sensitive) for read-only access. Press <Enter>.
6. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
IP Address Assignment
You must assign an IP address to the switch to gain management access over the network. You may also need to a establish a default gateway between the
switch and management stations that exist on another network segment. You can statically configure a specific IP address or direct the switch to obtain an
address from a Boot Protocol (BOOTP) or Dynamic Host Configuration Protocol (DHCP) server when it is powered on. Valid IP addresses consist of four decimal
numbers, 0 to 255, separated by periods. Anything outside this format is not accepted by the CLI program.

NOTE: Passwords are case sensitive.
NOTICE: CLI configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your
configuration changes in nonvolatile storage, you must use the copy command to copy the running configuration file to the startup configuration.
NOTICE: By default, the IP address is assigned to VLAN 1 through DHCP.
