device view, you must enter community strings that determine the access level
granted to the device.
Table 3 shows the default access community strings for the
Device Manager software.
SNMP Retry Count Number of times Device Manager retransmits polling information.
Timeout Length of each retry of each polling waiting period. When accessing the
device through a slow link, you may want to increase the timeout interval
