RPDiep commented on issue #3648: Security Group: limit returns in get_bridge_physdev to 1 URL: https://github.com/apache/cloudstack/pull/3648#issuecomment-544865583 @ustcweizhou I'm sure this is something now on the hypervisor, but it appears that corner cases exist in which a second line appears. As we only need one result, I added the `| head -1` in this commit. Here's the output you requested (I added the vnet filter) ``` root@n02:~# bridge -o link show | awk '/master cloudbr0 / && !/^[0-9]+: vnet/' 7: bond0.701 state UP @bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master cloudbr0 state forwarding priority 32 cost 2 7: bond0.701 state UP @bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master cloudbr0 ```
