Cabletron Systems EMM-E6 manual Monitoring Hub Performance

Page 24

Using the EMM-E6 Hub View

•Green indicates that the port is active; that is, the port has been enabled by management, has a valid Link signal (if applicable), and is able to communicate with the station at the other end of the port’s cable segment. Note that an AUI or transceiver port will display as active as long as it has been enabled by management, even if no cable is connected.

•Blue indicates that the port has been disabled through management.

•Yellow indicates that the port is enabled but does not currently have a valid connection. This usually indicates that the device at the other end of the segment is turned off, or that there is no cable attached.

•Red indicates that the port is enabled, but is not able to pass packets. This generally means that the port has been segmented by management after experiencing an excessive number of collisions; for a BNC (thin coax) port, however, this may only mean that no cable or terminator has been connected.

•Magenta indicates that the EMM-E6 can’t manage the device.

When the Admin Status port display option is active, only two colors apply: a port will be displayed in green if it is enabled by management, regardless of whether or not there is a cable attached or a valid link signal detected; a port disabled by management will display as blue.

When the FNB Channel option is active, an entirely different color scheme is employed: salmon = Channel A; light blue = Channel B; orange = Channel C, and grey = stand-alone.

Monitoring Hub Performance

The information displayed in the Hub View can give you a quick summary of device activity, status, and configuration. SPMA can also provide further details about hub performance via its four-level menu structure. The Device, Network, Module, and Port menus (Figure 2-6, below) give you control over the hub at four levels and give you access to the tools, menus, and windows that let you monitor specific aspects of hub performance, change hub display options, and set EMM-E6 operating and notification parameters. Remember, though many functions will operate the same at each level, those accessed via the Device menu control or provide information about all modules in the hub; those accessed via the Network menu control or provide information about all modules in a particular network, or channel; those accessed via the Module menu control or provide information about a single module; and those accessed via the Port menu control or provide information about a single port.
