GitHub user rajujith added a comment to the discussion: Error creating VLAN
@miloserdoff can you check for any stale bridge configurations on the host and fix them? Below is an example that works properly : `/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvlan.sh -v 1556 -p eth1 -b breth1-1556 -o add` the -p should be passed with the physical interface name but in your log, its having a bridge interface. `"Usage: %s: -o <op>(add | delete) -v <vlan id> -p <pif> -b <bridge name> -d <delete bridge>(true | false)\n"` GitHub link: https://github.com/apache/cloudstack/discussions/10190#discussioncomment-11842080 ---- This is an automatically sent email for users@cloudstack.apache.org.
