How many ip addresses should I assign to a port configured as breakout mode?

Should I assign ip address to each cable or just one ip address for whole breakout port?

Maryam,

When you set a port to breakout mode it essentially creates 4 new interfaces.

Say you pick port 0/12 as your breakout interface for 4x10g

Ethernet 0/12 is removed and in its place 4 new 10g interfaces are created; 0/12:1, 0/12:2, 0/12:3, and 0/12:4

At this point you can no longer configure e 0/x, the donor port, and your only option is to configure each port 0/x:1-4, or "cable", individually.

If you want them all to share an IP, you would need to put them all in the same VLAN and use a VE.
