Using the 7C0x SmartSwitch Hub View
2-30 Managing the Hub
Device Configuration
This polling interval controls how often a survey is conducted of the type of
equipment installed in the 7C0x SmartSwitch hub; information from this poll
would change the Hub View to reflect the addition and/or removal of a NIM or
NIMs.
Port Operational State
This polling interval controls the update of the information displayed in the Port
Status boxes for each port in the hub. Port state information varies according to
the Port Display Form which is currently selected.
Statistics
This polling interval controls how often the information displayed in the Port
Status boxes is updated when the Port Display Form is set to a rate or percentage.
Port Configuration
The Port Configuration options available for FDDI, Ethernet, Fast Ethernet, and
COM ports allow you to configure operating parameters specific to each port
type: for FDDI and standard Ethernet ports, you can set the Duplex Mode; for
Fast Ethernet ports, you can set a variety of duplex mode and negotiation
parameters; and for COM ports, you can select the operation you wish the port to
perform, and set any associated speed parameters. FDDI, Ethernet, and Fast
Ethernet Port Configuration windows are available from the Interface Application
Display Port menus; the COM Port menu is available in all Application Display
modes.
Configuring Ethernet and FDDI Ports
The Port Configuration window available for both Ethernet and FDDI ports
allows you to set an interface to either Standard or Full Duplex Mode. Full Duplex
mode effectively doubles the available wire speed by allowing the interface to
both receive and transmit simultaneously. This window will also display the
mode currently in effect on the selected interface.
To access the Port Configuration Window:
1. If necessary, put the Hub View into the Interface Application Display mode
(click either mouse button on the Module Index or Module Type box to display
the Module menu, drag down to Application Display, then across to select
Interface).
NOTE
SPMA generates network traffic when it retrieves the above-described information; keep
in mind that shorter intervals mean increased network traffic. Range limits for these
polling times are 0-999,999 seconds; however, an entry of 0 will be treated as a 1.
