Step 3 When the Login prompt appears, enter the user name provided with your switch and press Enter.
Step 4 When the password prompt appears, enter the password provided with your switch and press Enter.
After you successfully log in, a prompt appears that is similar to the prompt in the following example:

Configuring for Network Management
The Cisco MGX 8850 and Cisco MGX 8950 switches include a Simple Network Management Protocol
(SNMP) agent that you can configure for communications with a network management station such as
Cisco WAN Manager (CWM) or a third-party SNMP manager. When configured for SNMP
management, the switch accepts configuration commands from management stations and sends status
and error messages to the management station.
Typically, CWM operates on a workstation that is connected to an IP network; CWM uses IP over ATM
connections to connect to the Cisco MGX 8850 and Cisco MGX 8950 switches. For information on
establishing this type of access, see the “Setting Up ATM WAN Connections” section in Appendix C,
“Supporting and Using Additional CLI Access Options.”
To support the auto-discovery feature of CWM, ILMI should be brought up on all links between the
CWM workstation and the switches it will manage. For information on bringing up ILMI, see the
“Configuring ILMI on a Port” section in Chapter 6, “Provisioning AXSM Communication Links.”
The rest of this section describes the following procedures:
• Configuring the SNMP Trap Source IP Address
• Configuring the SNMP Manager Destination IP Address
• Configuring the Community String and General Switch Information
Configuring the SNMP Trap Source IP Address
The SNMP trap source IP address is sent to SNMP managers, such as CWM, in the SNMP trap Packet
Data Unit (PDU). This IP address identifies the source of the trap and can be used by the SNMP manager
to access the remote SNMP agent. This address must be configured to enable communications with an
SNMP manager.
Note If the trap manager IP address is not set, CWM will reject traps from the switch.
The switch can communicate with an SNMP manager over the LAN or ATM IP interfaces. In some
installations, the LAN IP interface will be used for CLI management and the ATM IP interface will be
used for SNMP management. When you select the SNMP trap manager IP address, you must select the
correct interface address.
To define the SNMP trap manager IP address, enter the cnftrapip command as follows:
8850_LA.7.PXM.a > cnftrapip <ipaddress>
