Description Fani Orestiadou 2016-05-20 07:47:17 UTC

Description of problem:
There is possibility to set initcwnd and initrwnd options via ip command but there is no way to perform this using the nmcli.

Example of ip command:
ip route add default via x.x.x.x dev ethX proto static initcwnd X

Would it be applicable to add this feature to nmcli settings ?

Version-Release number of selected component (if applicable): 
All versions of NetworkManager

Actual results: No way of setting initcwnd and initrwnd via nmcli

Expected results: Be able to configure those values using nmcli

Thank you

As you say, you currently can only configure basic attributes of a route.
E.g. no multi-path or policy-routing.





Current workaround:
===================


configure those routes in initscripts file
  /etc/sysconfig/network-scripts/rule-$NAME
  /etc/sysconfig/network-scripts/rule6-$NAME



to make this work also:

- ensure that the NetworkManager connection is handled via ifcfg-rh plugin (by default on RHEL). Basically, there should be a corresponding /etc/sysconfig/network-scripts/ifcfg-$NAME file for your connection.

- ensure dispatcher is enabled (by default on RHEL)
  $ systemctl status NetworkManager-dispatcher

- ensure NetworkManger-config-routing-rules package is installed (by default on RHEL). In rhel-7.3 this package will be renamed to NetworkManager-dispatcher-routing-rules. This package provides /etc/NetworkManager/dispatcher.d/10-ifcfg-rh-routes.sh which will apply the routes from the rule- file above.

Bug 1373698 is also about adding native support for route options in NM. I'm closing this as a duplicate.
