Appendix D Using the Subnetsdb File | HP Transcend Traffix Manager

136APPENDIX D: USING THE SUBNETSDB FILE

For example, if the SubnetsDB file was to contain the following entries with the same subnet address:

subnet	mask	name	domain
89.0.0.0	255.0.0.0	Group1	3com.com
89.0.0.0	255.255.0.0	Group2	3com.com

Any device matching both of these subnets would be placed in Group 2, as this has 16 set bits in its subnet mask, whereas Group 1 has only 8 set bits.

■If a device matches two subnets and both subnets have the same number of set bits in their masks, then Traffix Manager may assign the device to either of these groups.
