Timeliness Checks
The switch performs timeliness ch e cks to ensure that PDUs are not
reordered, delayed or replayed. These timeliness checks include the
following information:
■Number of reboots since the switch was upgraded from v5.x
application software to v6.x 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 i nformation,
the NMS inserts it in all PDUs that it se nds to the switch.
The switch discards any PDUs tha t contain:
■The incorrect number of switch reboots
■A 150-second or greater discrepancy in the number of seconds since
the last switch reboot.
Views
Overview
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 Cont rol Model
(VACM) MIB. Only users that have administrator access t o 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.
For information on how to configure a view, see “Configuring Views.”
