Figure3-7 Services Tree
The MIB is distributed as a text file (ASN.1) on a diskette which can be printed and used to compile
the MIB into an SNMP Manager. The MIB (and hence the MGX 8220 shelf) can also be managed
from StrataView Plus (Release 8.1 and higher). For complete details of managing the shelf from
StrataView Plus, refer to the Cisco StrataView Plus Operations Guide.
NoteMIB variables are identified as read-write or read only. Read-write variable can be accessed
by both GET and SET SNMP commands. Read only variable can be accessed by GET commands
only.
When setting a MIB variable in a table, the “enable” variable must also be set in the same SNMP
PDU.
TFTP User Interface
The MGX 8220 shelf in Release 4.1 supports the transfer of data files between the shelf and a
workstation using Trivial File Transfer Protocol (TFTP). The functions provided by these file
transfers are the configuring and collection of statistics and the downloading of MGX 8220
firmware.
In order to perform a file transfer the workstation must establish connectivity with the shelf either
through the control port (using SLIP) or through the in-band port. In both cases TCP/IP protocol is
employed and the shelf must be assigned an IP address. For details on establishing connectivity, refer
to the following section in this chapter, “Setting Up Management Connectivity to the MGX 8220
Shelf”.
