Using the Built-in Editor

The AT-8800 Series Switch has a built-in full-screen text editor for editing script files stored on the switch file subsystem. Using the text editor you can run script files manually, or set script files to run automatically at switch restart, or on trigger events. Figure 11 on page 60 shows a example screen shot of the text editor. To start the editor with a new file or an existing file, enter the command:

EDIT [filename]

Figure 11: The editor screen layout.

The editor uses VT100 command sequences and should only be used with a

VT100-compatible terminal, terminal emulation program or Telnet client.

To display editor Help at any time while in the editor press [Ctrl/K,H]; that is, hold down the Ctrl key and press in turn the K key then the H key.

For more information about the inbuilt editor, see the Operation chapter in the

AT-8800 Series Switch Software Reference.

SNMP and MIBs

You can remotely monitor some features of the switch using Simple Network

Management Protocol (SNMP).

For information about the MIBs supported by the switch, see Appendix C:

SNMP MIBs in the AT-8800 Series Switch Software Reference.

The SNMP agent is disabled by default. To enable SNMP, enter the command:

ENABLE SNMP
