Adding new segment.

Unanswered Question
Jun 27th, 2007

Hi All,

I have to add new segment in my network and also change the subnet mask from /26 to/25.

What procedure can I follow to do this setup?

I have attached my network upgrade plan.

What all config need to be done in my L3 switch and L2 switch?

Can somebody suggest how to go for it?

If you don't want renumbering on the VLANs you can either use secondary subnets (undoubtly it also has some drawbacks) or create more VLAN's and route between them.

Hope it helps,

Is the vlan20 created at all? I just see interface vlan20 but there is no any port assigned to vlan20. If you have created vlan20 on other switch (in vtp server mode) then vtp should advertise it through the rest (excluding vtp tranparent mode).

Hope it helps,
