Managing the Hub
Console Command Reference
| For Network Management Security. The security violations are indicated |
| by the Security LED flashing and the violating network management station’s |
| address being displayed on the Status command screen. |
| A network management security violation occurs when a network manage- |
| ment station that is not on the authorized management station list attempts |
| to issue SNMP “set” commands to the hub, or when a network management |
| station uses an invalid password (SNMP community name) to access the hub. |
| See the Managers command description, earlier in this chapter, for |
| information on the authorized management station list. By default, all network |
| management stations are allowed to manage the hub. Under this configura- |
| tion, network management security violations will not occur. |

N o t e s | If the port was disabled because of a security violation |
| (Disable Port = YES), to |
| command for that port. |
| The Security Clear command does not remove the cause of the security |
| violation, for example the wrong device being attached to a port. Until the |
| cause is removed, the violation can reoccur immediately after issuing |
| the SE CL command. It may appear as if the violation indication was never |
| cleared. |

SPeed <new speed>
Change the console port baud rate. Normally, the baud rate is automatically sensed. Use this command if you want to set the baud rate explicitly to 1200, 2400, 4800, 9600, 19200, or 38400. You will be prompted to set the terminal’s baud rate to the same speed and to press Enter for the prompt. Example SP 9600. (Sets the baud rate to 9600.)
STatus
To display status information for the hub. The status information includes:
■the time elapsed since the last reset (see the Reset command),
■the hub’s MAC address,
■if a network management security violation has occurred, the MAC address of the violating network management station,
