Cabletron Systems CSX1000, CSX1200 manual Snmp

USER’S GUIDE

4.If the remote resources can not be seen even when the connection is up, then make sure the AppleTalk address of the remote device is valid. If the remote device is on an unnumbered network, then AppleTalk an address of 0.0 must be configured for the remote device in the device table. If it is on a numbered network, the AppleTalk address does not need to be configured for the device in the device table. However, if it is configured, it must match the AppleTalk address configured on the remote device.

SNMP

Problem:

The SNMP Agent is not functioning.

Action:

1.Check the configuration of the CyberSWITCH. In order for the SNMP Agent to become enabled, both the IP option and the SNMP Agent must be enabled in the CyberSWITCH configuration. (You may check the configuration by using the options and snmp commands in Manage Mode; however, you can only make changes to these items by using CFGEDIT).

2.Enter the dr command at the administrative console. If the following message appears, the IP subsystem has initialized successfully:

[IP] IP router is initialized successfully

3.However, if one of the following messages appears, there is an unexpected condition present within the CyberSWITCH software. Contact Customer Support.

[SNMP] SNMP initialization failure - unable to allocate necessary memory

[SNMP] SNMP initialization failure - unable to open UDP port

Problem:

The CyberSWITCH does not respond to SNMP requests.

Action:

1.Enter the command snmp stats at the administrative console. If an “SNMP is not enabled” message appears, you must first enable the SNMP Agent (using CFGEDIT).

2.If the SNMP statistics are displayed, check the value of the “snmpInBadVersions” statistic. If it is non-zero, the Network Management station is generating request PDUs with an incompatible SNMP version number. Such requests are discarded by the SNMP agent.

3.Check the value of the “snmpInBadCommunityUses” statistic. If it is non-zero, the community name specified in the request PDUs does not have the proper access rights to perform the desired request, and the request is discarded. To correct this problem, reconfigure the MIB access level for the desired community name to the desired access level.

4.Check the value of the “snmpInASNParseErrs” statistic. If it is non-zero, the network management station is generating request PDUs that are not properly encoded in ASN.1 format. Such requests are discarded by the SNMP agent.
