Cisco Systems MGX 8220 manual Setting Trap Managers, VPI/VCI Mapping

Chapter

Setting Trap Managers

Use the following syntax to configure the BNM interface:

shelf.1.3.ASC.a > cnfbnmif -if <interfaceFormat>

<interfaceFormat> = 2-3, 2: UNI, 3: NNI

Configure the BNM interface to UNI format,

shelf.1.3.ASC.a > cnfbnmif -if 2

If the BNM-T3 card is being used, the ATM line must be configured with PLCP.

Note The BNM interface cannot be configured while connections exist on the MGX 8220 shelf. The clrallcnf command can be entered to clear the entire configuration. This command will also reset the MGX 8220 shelf and terminate all telnet sessions.

The interface format can be confirmed with the dspbnmif command and the response of “bnmLineInterfaceFormat: bnmUni.”

Setting Trap Managers

In stand-alone applications, trap managers are configured through the CLI entering either the cnftrapmgr command or the addtrapmgr command.

Trap managers registered (added) entering the cnftrapmgr command will age. That is to say the trap manager will be disabled automatically after 30 minutes and must be reregistered if it is to continue to exist. The function of reregistering is normally accomplished by the Cisco WAN Manager (CWM), but since CWM cannot be used for stand-alone applications, there is no method for reregistering trap managers.

In stand-alone applications, therefore, the addtrapmgr command should be entered to register a trap manager. Using this command the trap manager does not age and exists until de registered by the deltrapmgr command. Once a trap manager is registered by the addtrapmgr command it can be modified by the cnftrapmgr command and the trap manager will still not age.

Current trap managers can be displayed using either the dsptrapmgrs or dsptrapmgr commands. The dsptrapmgrs command displays all current trap managers but does not include time-out information. The dsptrapmgr command displays the status for a single specified trap manager including the time-out status.

Refer to the Cisco MGX 8220 Command Reference for details of these commands.

VPI/VCI Mapping

When creating connections on the MGX 8220 shelf the user does not explicitly assign VPI and VCI values. Instead, the MGX 8220 shelf takes user-entered values such as DLCI, LCN, and so forth, and uses mapping algorithms to calculate VPI/VCI values. In stand-alone applications, the user needs to know how this mapping works since these VPI and VCI values must be configured into the connected router or ATM switch.
