hi, just a quick question. i wanted to know what does this command do - interface ip-acl add src-ip 0.0.0.0/0 port 2.1
as i can't seem to find the command reference docs. thanks.
Welcome to the Ciena Community.
For details on the interface ip-acl command, it can be found in the following documentation (which may vary depending on the SAOS release), assuming you are referencing it in regards to Ciena's 39xx/51xx Packet Networking devices.
In summary, the interface ip-acl commands provides basic security for IP protocols that terminate within the network device. For example, you can restrict access to the device by configuring a white-list (or permit list) of IP source addresses, physical ports, and/or protocols.
Based on the command example you have specified above, the configuration of that line will only permit frames arriving on port 2.1 to communicate with the device (for example, through the remote interface).
Please feel free to ask any further questions if needed.
Thanks for the reply and explaining what the command does, it is clearer to me now.
Thanks as well to Heather.
