ProLiant BL p-Class GbE2 Interconnect Switch Application Guide

Ports and trunking 33
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 GbE2
Interconnect Switches A and B together. Since this is the default configuration, you do not need to configure
trunk group 1 on either GbE2 Interconnect Switch.
• 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 GbE2 Interconnect Switch are configured so that there is a link to each
router for redundancy.
Prior to configuring each GbE2 Interconnect 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 HP ProLiant BL p-Class GbE2 Interconnect Switch Command Reference Guide.
Configuring trunk groups (CLI example)
1. On Switch A, configure trunk groups 5 and 3:
>> # /cfg/l2/trunk 5 (Select trunk group 5)
>> Trunk group 5# add 19 (Add port 19 to trunk group 5)
>> Trunk group 5# add 20 (Add port 20 to trunk group 5)
>> Trunk group 5# ena (Enable trunk group 5)
>> Trunk group 5# apply (Make your changes active)
>> # /cfg/l2/trunk 3 (Select trunk group 3)
>> Trunk group 3# add 21 (Add port 21 to trunk group 3)
>> Trunk group 3# add 22 (Add port 22 to trunk group 3)
>> Trunk group 3# ena (Enable trunk group 3)
>> Trunk group 3# apply (Make your changes active)
>> Trunk group 3# save (Save for restore after reboot)
