NEC INTELLIGENT L2 SWITCH N8406-022A - Manual (Page 30)

Ports and trunking 30
Port trunking example
In this example, the Gigabit uplink ports on each switch, and the crosslink ports are configured into a total of five
trunk groups: two on each switch, and one trunk group at the crosslink between the two switches. All ports operate
at Gigabit Ethernet speed.
NOTE: The actual mapping of switch ports to NIC interfaces is dependant on the operating system software,
the type of server blade, and the enclosure type. For more information, see the User’s Guide.
Figure 1 Port trunk group configuration example
The trunk groups are configured as follows:
•
Trunk group 1 is configured by default on the crosslink ports 17 and 18, which connect the switches 1 and 2
together. Since this is the default configuration, you do not need to configure trunk group 1 on either switch.
By default, ports 17 and 18 are disabled.
•
Trunk groups 2-5 consist of two Gigabit uplink ports each, configured to act as a single link to the upstream
routers. The trunk groups on each switch are configured so that there is a link to each router for redundancy.
Prior to configuring each switch in this example, you must connect to the appropriate switch CLI as the
administrator. For details about accessing and using any of the commands described in this example, see the
Command Reference Guide.
