Table 11: Creating the /etc/vlan.alt<num> files
5.Place the appropriate VLAN ID tag into the vlan.alt <num> file(s).
Each VLAN must be assigned a unique identification number. Even though the maximum number of VLANs that can be configured on each adapter is 64, any particular VLAN can be assigned an identification number between 1 and 4094. The VLAN tagging format follows the guidance provided in IEEE
The VLAN identifier numbers must be placed into each appropriate vlan.alt <num > file to which the adapter is a member.
Example: Consider a server with a single adapter. The server is a member of two VLANs, with VLAN identifiers 383 and 777. The contents of the first file, /etc/vlan.alt0 , would be "383" and the contents of the second file, /etc/vlan.alt100 , would be "777".
Use your regular text editor to put the VLAN identifier number into the appropriate vlan.alt <num> file. Be certain that there are no spaces, blank lines, or extra characters. The identifier can be entered in decimal (e.g. 383), octal (e.g. 0577), or hexadecimal (e.g. 0x17F) format.
If you are finished with all optional configurations, reboot the system.
Changes to the optional configuration parameters (VLAN, Jumbo Frame, or Dual Homing) do not take effect until you reboot the system. If you will be making changes to the other optional parameters during your configuration session, you should wait to reboot until those changes are complete.
If you modify parameters and put the system into service before rebooting, you may experience configuration problems.
Perform this command to reboot the system:
