Cisco Catalyst 2960 Series, Configuration Manual

Page: 1747 / 2288

EEM 3.0 introduced the following features:
• Class-based scheduling--The EEM policies will be assigned a class using the class keyword when they
are registered. EEM policies registered without a class will be assigned to the default class.
• High performance Tcl policies--Three new Tcl commands are introduced event_completion , event_wait ,
and event_completion_with_wait .
• Interactive cli support--The synchronous applets are enhanced to support interaction with the local
console (TTY). Two new IOS commands,
action gets and action puts, are introduced to allow users to
enter and display input directly on the console.
• Variable logic for applets--The Variable Logic for EEM Applets feature adds the ability to apply
conditional logic within EEM applets. Conditional logic introduces a control structure that can change
the flow of actions within applets depending on conditional expressions.
• Digital signature support--A new API performs digital signature verification for a Tcl script to check it
the script is signed by Cisco before execution.
• Support authenticating e-mail servers--The
action mail
command is modified to include an optional
username and password.
• SMTP IPv6 support--The keyword
sourceaddr
is added in Tcl e-mail templates to specify either an
IPv6 or IPv4 address.
• SNMP library extensions--The EEM applet action info and Tcl sys_reqinfo_snmp commands are
enhanced to include functionality for SNMP getid, inform, trap, and set-type operations.
• SNMP Notification IPv6 support--IPv6 address is supported for the source and destination IP addresses.
• CLI Library XML-PI support--Provides a programmable interface which encapsulates IOS command-line
interface (CLI) show commands in XML format in a consistent way across different Cisco products.
Customers using XML-PI will be able to parse IOS show command output from within Tcl scripts using
well-known keywords instead of having to depend on the use of regular expression support.
Embedded Event Manager 3.1
EEM 3.1 introduced one new event detector:
• SNMP Object--The Simple Network Management Protocol (SNMP) object trap event detector provides
an extension to replace the value when an SNMP trap with the specified SNMP object ID (OID) is
encountered on a specific interface or address.
EEM 3.1 added an enhancement to the following event detector:
• SNMP Notification--The SNMP notification event detector now can wait and intercept the outgoing
SNMP traps and informs.
EEM 3.1 added enhancement to the following action:
• Specify facility--The action syslog command has been enhanced to specify syslog facility.
EEM 3.1 introduces the following features:
• Provides the ability to create a short description for the registered policy--A new
description
command
has been introduced to register policies with a brief description in Cisco IOS CLI and Tcl policies. The
