Basic LS2020 Configuration Tasks
On the other hand, if you wish to change any configuration data, answer “N” at the chassis
and network processor information query and repeat this step in its entirety. You will be
prompted by the configuration script to re-enter all the applicable network management
information for your LS2020 switch.
Configure trunk port information (Y/N) [N] N
Creating minimum configuration database...done.
Similarly, if you respond N to the above trunk port configuration query, the system reports
that it is creating a minimum configuration database and that you have completed the basic
configuration procedure.
However, if you respond Y to the trunk port configuration query, proceed with Step 6 below.
Step 6 If your LS2020 switch is not directly attached to a LAN to which the NMS is also attached,
you must configure a trunk so that SNMP configuration traffic can flow between the new
LS2020 switch, the LS2020 network at large, and the LS2020 switch attached to the NMS.
In operational terms, the trunk port will be used to load a full configuration over the LS2020
network.
The trunk port configuration parameters you specify depend on the type of trunk port that you intend
to use for SNMP configuration traffic. For detailed information about the various trunk port
configuration parameters supported by the LS2020 switch, refer to the chapter in the LightStream
2020 Configuration Guide that describes “port attributes.”
However, for the sake of example, a trunk port for a low-speed card has been selected to
demonstrate the trunk port configuration procedure. In this particular case, proceed as
directed by the following configuration script:
Configure trunk port information (Y/N) [N] y
Trunk Card Type:
1) Low Speed
2) T3
3) E3
4) OC3
Specify the trunk card type (1-4): 1
Specify the trunk card slot number (1-10): 3
Specify the port number (0-7): 0
DCE/DTE Type:
1) DCE
2) DTE
Specify the DCE/DTE type (1-2): 1
