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 another device are also configured as LACP, the switch and the
other device will negotiate a trunk link between them. If an LACP trunk
