Web-Mgt: The SNMP settings, contact information, and MIB root OID are accessible through the Web-Mgt
only. To customize these parameters, use the procedures detailed in "Web-Mgt" on page 47, selecting

any time. All changes become effective immediately after clicking
SNMP Contact Settings
The information entered in the four SNMP Contact settings is included in the Management Information Base
(MIB) file for the ISE and in SNMP GetRequest and Trap notification packets. The SNMP Contact information
settings are:
•
Community string
•
Contact information
•
Organization

Description
MIB Root OID Setting
The ISE Root OID Name and Number are also displayed.
When any change to the four Contact Information parameters is saved by clicking
the system automatically regenerates the MIB file to include the new information.
Event Subscriptions
Event subscriptions provide the means to designate which events are to be forwarded to the SNMP Client
Application. Upon an event, the system checks this list to determine whether to send the event as an SNMP
trap to the SNMP Trap Destination list (see "SNMP Trap Destination Setup" this page). SNMP traps are
datagrams and do not have guaranteed delivery. Traps are sent only once and are not saved locally. Event
subscriptions are configured from the Web-Mgt only; they cannot be configured from the CLI.
To subscribe, select events from the
list. Use the
Selected Subscriptions
The Web-Mgt displays the Available Subscriptions and Selected Subscriptions lists for each Network Port on
the ISE (one port for each MRC). These subscription lists are independent and should be selected for both
ports. To obtain consistency in trap generation between the two MRCs, it is advisable to subscribe to the same
events on both Network Ports.
Trap service is provided by one of the two MRCs; if the trap-serving MRC experiences an exception causing a
reboot, the surviving MRC resumes trap service using only the traps and destinations defined for itself. Traps
defined only for an out-of-service MRC are not sent by the surviving MRC. Should trap service need to be
restarted on the surviving MRC, some traps may be lost during the transition.
SNMP Trap Destination Setup
The SNMP trap destination setup allows specification of site-specific IP addresses to which the selected
SNMP events (see "Event Subscriptions" ) are sent. Events can be sent to different IP addresses from each
port if desired. Duplicate IP addresses are not permitted in the address lists and cannot be added.
Web-Mgt: SNMP trap destinations are configurable from the Web-Mgt only; they cannot be configured from
the CLI. To set up the SNMP trap destinations, follow these steps for each network port:
1. Enter an SNMP trap destination IP address in the Enter Address field.
2. Click
to move the address from the Enter Address field to the Address List.
