Disabling the firewalling of LLDP pakets on +| the network card allows the operating system (= Linux kernel) to actually recieve +| the pakets and re-establish the bonded connection. + +| **Enabling link-down-on-close** +| Many Intel network cards such as the X700 Series do not take down the link +| when the corresponding interface is deconfigured. This is in contrast to the +| consumer (Intel) network cards that usually do this. Therefore, without enabling +| the link-down-on-close, most assumptions of HA stacks (e.g. pacemaker/corosync) +| are not met and can lead to various unwanted effects. Enabling this options +| restores the usual behaviour. + +See also +======== + +| linux-i40e(1), +| ethtool(8), +| https://www.kernel.org/doc/Documentation/networking/ice.txt + +Homepage +======== + +More information about service-tools and the Open Infrastructure project can be +found on the homepage (https://open-infrastructure.net). + +Contact +======= + +Bug reports, feature requests, help, patches, support and everything else are +welcome on the Open Infrastructure Software Mailing List +<software@lists.open-infrastructure.net>. + +Debian specific bugs can also be reported in the Debian Bug Tracking System +(https://bugs.debian.org). + +Authors +======= + +service-tools were written by Daniel Baumann +<daniel.baumann@open-infrastructure.net> and others. diff --git a/linux/share/systemd/linux-ice.service b/linux/share/systemd/linux-ice.service new file mode 100644 index 0000000..ee8a727 --- /dev/null +++ b/linux/share/systemd/linux-ice.service @@ -0,0 +1,17 @@ +# Open Infrastructure: service-tools + +[Unit] +Description=setting recommended options for the Linux ice device driver +Documentation=man:linux-ice +Before=network.target + +[Service] +Type=oneshot +RemainAfterExit=yes +ExecStart=/usr/bin/linux-ice start +ExecStop=/usr/bin/linux-ice stop +StandardOutput=journal +StandardError=journal + +[Install] +WantedBy=multi-user.target |
