SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide Switch Configuration
Switched Port Analyzer Menu from the Configuration
Menu
The Switched Port Analyzer screen is accessed from the Configuration menu. This
screen and its submenus are presented in Chapter 9, “Monitoring Port Traffic”.
CrossLink
A CrossLink connection is used to improve interswitch bandwidth. A CrossLink is
used to connect two switches from the SmartStack STS16-20RM family with two
to eight links (on SmartStack STS16-20D the maximum is 4 ports). A CrossLink
provides bandwidth of from 32 to 128 Mbps in half-duplex mode, or from 64 to 256
Mbps in full-duplex mode.
➽ Note: On SmartStack STS16-20D only ports 17 to 20 allow CrossLinks to be
configured.
Figure 26. Setting Up CrossLinks
The CrossLink feature affects other SmartStack STS16-20D/STS16-20R features
in the following ways:
•
Half-duplex and full-duplex. A single CrossLink can include a combination of
half-duplex and full-duplex connections—for example, a CrossLink
containing three ports can have two full-duplex and one half-duplex
connections. However, each pair of interconnected ports must both be either
half-duplex or full-duplex.
