ATM Uplink Module

Overview

The ATM Uplink module supports only SNMPv1 and v2. It does not support SNMPv3. To make secure SNMPv3 access to the ATM Uplink module possible, the application software uses a proxy forwarder.

The proxy forwarder converts SNMPv3 requests to SNMPv1 requests and then internally forwards them to the ATM Uplink module. When the ATM Uplink module responds to requests, the proxy forwarder converts the SNMPv1 responses to SNMPv3 responses and forwards them to the originator of the initial request.

To identify a PDU as destined for the ATM Uplink module, the NMS inserts the engine ID and context name of the ATM Uplink module. The engine ID and context name of the ATM Uplink modules are as follows:

• Engine ID--Engine ID of the switch, where the slot number of the ATM Uplink module is added to the last octet.

For example, if the engine ID of the switch is 00:00:1a:e9:01:7f:00:00:01:00:00:00 and an ATM Uplink module is in slot 11, the engine ID of the ATM Uplink module is 00:00:1a:e9:01:7f:00:00:01:00:00:0B. (B is the hexidecimal value for 11.)

• Context name--ATM<mod-num>, where <mod-num> is the slot number of the module.

You must configure the engine ID and context name of the ATM Uplink module in the NMS.
