Work with Map-Passalls and Port Mirroring in GigaVUE‑FM
In addition to regular maps, GigaVUE‑FM also makes it possible to create map-passall maps and configure tool-mirror ports for packet distribution.
A map-passall map lets you send all packets on a network port one or more tool ports or tool GigaStream on the same node or between the nodes in a cluster, irrespective of the packet distribution already in place for the ports.
Tool-mirror ports let you configure all a pass-all between two tool port or tool port and a too GigaStream on the same node, irrespective of the packet distribution already in place for the ports.
These map-passall maps and tool mirror ports are particularly useful in the following situations:
|
■
|
Redirecting all traffic to IDS monitors regardless of any map rules applied to network ports. |
|
■
|
Temporary troubleshooting situations where you want to see all traffic on a port without disturbing any of the maps already in place for the port. |

Rules for Map-Passalls and Port Mirroring
Keep in mind the following rules for the map-passalls and tool mirrors:
|
■
|
You can set up a map passall from: |
|
o
|
Network port(s) to tool port(s) on the same node. |
|
o
|
Network port(s) to one or more GigaStream. |
|
■
|
You can set up a tool mirror from: |
|
o
|
Tool port to tool port(s) on the same node. |
|
o
|
Tool port to GigaStream(s) configured with the advanced-hash algorithm on the same node. |
Note: The destination for a map-passall or tool-mirror can be a tool port, a hybrid port, a circuit port, a tunnel, a tool GigaStream, or a hybrid GigaStream.
|
■
|
You cannot set up a map-passall or tool mirror from network port to network port. To be able to create such functionality, refer to Port Access and Map Sharing. |
|
■
|
A map-passall can cross line cards or modules – they can start on one line card/module and end on another in the same node. Also, they can cross nodes in a cluster. |
|
■
|
A tool mirror can cross line cards or modules – they can start on one line card or module and end on another in the same node. They cannot, however, cross nodes in a cluster. |
|
■
|
Tool mirrors are not allowed from tool GigaStream to tool port. |
|
■
|
Tool mirrors are not supported on tool ports with copper SFPs installed or on 100Gb ports with CFP2 transceivers. |
|
■
|
A map-passall cannot be used with a port that is part of a port-pair. |
View and Delete Map-passalls
Map-passalls are created by selecting Subtype Pass All for a Type Regular map. You can view the map by clicking on the map alias on the Maps page to open the Quick View for the map. To delete a pass-all map, select the map on the Map page and click Delete.
