Constraints of Operating Access-T with SNMP
The following constraits exist when operating Access-T when SNMP manage-
ment is implemented:
•
Access to the normal terminal interface screen may be denied de-
pending on the type of device attached to the Supervisory port.
•
Access-T processes only one request at a time, in the order received.
Although the input buffer (1500 bytes capacity) can store additional
requests, it is recommended that an SNMP manager not make an-
other request until a response is received or a timeout occurs.
•
Access-T does not support fragmentation of IP packets on either
transmit or receive.
•
On the SNMP manager, the timeout for requests depends on the
following:
•
Tranmission delays between the manager and Access-T.
•
Whether the request is for the master Access-T or a slave on
the chain.
•
Whether the request is for far-end information.
•
The number of SNMP variables reqeusted.
•
User activity on the Craft Port.
•
Whether polling is enabled for non-existent or non-reporting
slave nodes.
