Administrative Problems (Netview/SNMP/Telnet)
This section details problems occuring during the administration of your ONcore hub (PING,Telnet,TFTP,SNMP/ATMC).
PING: | Your | ONcore | hub | cannnot | ping your management | station. |
|
|
|
|
|
|
| ||
Steps | to | Take: |
|
|
|
|
|
|
|
|
|
|
|
|
|
1. Since all | the management | services are | running over | IP, | you have to ensure that | ||||||||||
your | ONcore | hub | can | ping | the | destination | station | where you | will run | either Telnet, | |||||
the | TFTP daemon (TFTP server), or the SNMP | manager (ATMC). | If | the ping fails, | |||||||||||
see | previous | sections | on | ping | failures | in | Classical | IP | or | LAN | emulation | networks. | |||
Telnet: You cannot Telnet to your ONcore hub from your management station.
Steps to Take:
1. If | the | ping | does | not | work, | see | previous | sections | on | ping | failures. |
|
| ||||||||||||||
2. Someone | is | already | logged | on | the | ONcore |
| hub | by | another Telnet session. It is not | |||||||||||||||||
possible | to | have more than one Telnet session | per | ONcore | hub. |
|
|
|
| ||||||||||||||||||
To | know | from | which | station | the |
| other | Telnet | session |
| is active, use the ATMC SVC | ||||||||||||||||
Tracking | tool | to | determine | at | least | which |
| SVCs | are |
| connected | to | the internal | port of | |||||||||||||
the | ONcore | hub (interface 1). You will then know | the ATM addresses of the remote | ||||||||||||||||||||||||
ends, as | well | as | the ONcore | hub | ports | to | which | they | are | connected | to. |
| |||||||||||||||
Note: | It | is | recommended to set the Terminal Timeout parameter | to a |
| ||||||||||||||||||||||
value, | to | force | Telnet | sessions | to | close |
| themselves | after | some | inactivity. |

TFTP: Upload fails from your | ONcore | hub |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| ||||||
Explanation: |
| The | upload can be done either | from | the | terminal | console | (console or |
| ||||||||||||||||||
Telnet) | or | from | the SNMP Manager (ATMC or MIB Browser). |
|
|
|
|
|
|
|
|
| |||||||||||||||
Before | performing | any upload, | make | sure | that |
| the machine | hosting | the TFTP | server | can | ||||||||||||||||
ping | the | ONcore hub. |
