Chapter 4: Adding Extra Interfaces

The default cOS Core virtual machine has three virtual interfaces configured for cOS Core. These have logical cOS Core names If1, If2 and If3.

If more virtual interfaces are required, these can be added later but must be manually configured.

The steps are as follows:

  1. Add the virtual interfaces to the Hyper-V virtual machine.

  1. Although new virtual interfaces have been added to the virtual machine, cOS Core will not automatically add these to the current configuration. To add the interfaces, run the following cOS Core CLI command: 

    Device:/> pciscan -cfgupdate

    The output from this command will confirm that a new interface has been added. If it is the first added and no previous ones have been deleted it should have the logical name If4.

    Follow the pciscan command with the activate and commit CLI commands to save the configuration changes.

[Warning] Caution: Adding and deleting cOS Core interfaces

cOS Core allows logical interfaces to be deleted. If this is done, the ordering of subsequently added logical interfaces can become unpredictable and may not necessarily have the first logical name that is available. For example, if cOS Core interface If2 is deleted from the configuration, the next interface added using pciscan may not become If2.
