Timeliness Checks

Views

Overview

5-4
The switch performs timeliness checks to ensure that PDUs are not
reordered, delayed or replayed. These timeliness checks include the
following information:
Number of switch reboots since v6.0 was installed or since the last
initialization of NVRAM.
Number of seconds since the last switch reboot.
When the NMS starts up, it sends the switch a request message for this
information. The switch responds with a report PDU that contains the
information. Once the NMS and switch have synchronized this information,
the NMS inserts it in all PDUs that it sends to the switch.
The switch discards any PDUs that contain:
The incorrect number of switch reboots
A 150-second or greater discrepancy in the number of seconds since
the last switch reboot.
A view defines the specific object identifiers (OIDs) that either can or
cannot be accessed by the user groups to which the view is assigned.
View information is stored in the View-Based Access Control Model
(VACM) MIB. Only users that have administrator access to the switch can
use CLI commands to modify this MIB. Users that have administrator
access can, however, give specific user groups read-write access to the MIB.
Users or community strings assigned to those user groups can then use
SNMP to view or modify the MIB.
