Token Ring Secured Station Configuration

!

CAUTION

The 9T122-08 Token Ring Secured Station ConÞguration Screen (Figure 8), allows you to control access to the moduleÕs token ring network.

The Disabled mode (by default) allows all new stations to enter the ring.

When ring security is enabled in Alarm Only mode, the module stores the MAC address of each station on the token ring network in a secure database or Òallowed list.Ó The module can store up to 250 station MAC addresses on the allowed list. The module retains the allowed list in its battery-backed Non- Volatile Random Access Memory (NVRAM). When the module is powered up or reset, all MAC addresses are retained and ring security is reenabled automatically.

The Alarm Only mode allows new stations to enter the ring, but a Òstation addedÓ trap/alarm notiÞes the Network Management Station (NMS) of the event. The trap/alarm includes the new stationÕs MAC address so that the network manager can decide if the new station should be allowed on the ring.

Do not enter Remove/Alarm mode without Þrst entering the Alarm Only mode or adding nodes to the allowed list. All nodes not appearing in the list, currently active on the ring, WILL BE REMOVED!

The Remove/Alarm mode sends a ÒRemove Station MAC Frame CommandÓ to new stations attempting to enter the ring, and a trap/alarm to the NMS informing it of the action taken. If, after three attempts, the station (outside the hub) cannot be removed from the ring, a trap/alarm is sent to the NMS informing it that Òthe station could not be removed.Ó Also, the port is disabled for the station directly connected to the hub and a trap/alarm is sent indicating port removal.

To access the 9T122-08 Token Ring Secured Station ConÞguration Screen from the Module SpeciÞc ConÞguration Menu:

1.Use the arrow keys to highlight the Token Ring Security option.

2.Press the Enter key.

The 9T122-08 Token Ring Secured Station ConÞguration Screen (Figure 8), appears.
