CLI – The following example globally enables DSCP Priority
service on the switch, maps DSCP value 1 to CoS value 0 on port
5, and then displays all the DSCP Priority settings for that port.
(Note that the setting is global and applies to all ports on the
switch.)
Port Trunk Configuration
Ports can be combined into an aggregate link to increase the
bandwidth of a network connection where bottlenecks exist or to
ensure fault recovery. You can create up to six trunks at a time,
with any single trunk containing up to four ports.
The switch supports both static trunking and dynamic Link
Aggregation Control Protocol (LACP). Static trunks have to be
manually configured at both ends of the link, and the switches
must comply with the Cisco EtherChannel standard. On the other
hand, LACP configured ports can automatically negotiate a trunked
link with LACP-configured ports on another device. You can
configure any number of ports on the switch as LACP, as long as
they are not already configured as part of a static trunk. If ports on
