Hi Nawraj, I tagged this as Spirent TestCenter. Let me know if that is correct. Sorry I'm not and API guy so I do not know the answer to your question.

Actually it is related to TCL scripting. Anyway we are trying to implement same in STC. Shouldn't be an issue.

There are many different methods to achieve what you want. I am not sure if you are talking about Devices, or Raw StreamBlocks. I have attached a PDF that describes how to create multiple Devices each with a different MAC and IP Address. This is old material and references Hosts (Host has since been replaced with Device within the API) however, the process is the same.

I am trying to acheive this through HLTAPI. In one port i need to create 5K devices and each device should have unique mac address. for {set i 1} {$i <= $num_blocks} {incr i} { set device_ret1 [sth::pppox_config\ -mode create -encap ethernet_ii_vlan -protocol pppoe\ -port_handle $port1 -num_sessions 1 -auth_mode chap \ -username bnguser$i@cisco.com -password cisco123 \ -mac_addr "00:10:94:01:00:02" -mac_addr_step "00:00:00:00:00:01" \ -vlan_id 100 \ ] Though we have mac_addr_step option here, but it won't do increment when we are using it under for loop . hence need a separate tcl proc to implement same. Similar is the case while creating bgp routes, we don't have -next_hop_step option for next_hop ip increment so need a tcl proc to increment ip address too.
