FIGURE 5-2 Ethernet Tag Header Format
By default, a single VLAN is configured for every port, which groups all ports into
the same broadcast domain, just as if there were no VLANs at all, VLAN tagging for
the switch port turned off.
▼ To Configure Static VLANs
1. Create one hostname6.cenum file for each VLAN which will be configured for each
adapter on the server, using the following naming format that includes both the
VID and the physical point of attachment (PPA):
VLAN logical PPA = <1000 * VID> + <Device PPA>
ce123000 = 1000*123 + ce
This format limits the maximum number of PPAs (instances) you can configure to
1000 in the /etc/path_to_inst file.
For example, on a server with the Sun GigabitEthernet/P 3.0 adapter having an
instance of 0, that belongs to a member of two VLANs, with VID 123 and 224, you
would use ce123000 and ce224000, respectively, as the two VLAN PPAs.
