Commands for Configuring Slots and Ports on a Switch
Load sharing is most useful in cases where the traffic transmitted from the switch to the load-sharing
group is sourced from an equal or greater number of ports on the switch. For example, traffic
transmitted to a two-port load-sharing group should originate from a minimum of two other ports on
the same switch.
You can view port status on the switch using the
show ports
commands. These commands, when used
with specific keywords and parameters, allow you to view various issues such as real-time collision
statistics, link speed, and packet size. On the
“i” series of switches, flow control can also be viewed with
the
show ports
command.
Commands that require you to enter one or more port numbers use the parameter
<portlist>
in the
syntax. On a modular switch, a
<portlist>
can be a list of slots and ports. On a stand-alone switch, a
<portlist>
can be one or more port numbers. For a detailed explanation of port specification, see
“Modular Switch Numerical Ranges” or “Stand-alone Switch Numerical Ranges” in Chapter 1.
Link Aggregation Control Protocol (LACP) is an extension to the existing sharing implementation. It
provides several features:
• LACP protocol control of sets of links
• Loopback detection
• Configuration verification for systems connected using LACP
