Virtual Port Rules

The following rules apply to single virtual ports:

1.

A given vport can only belong to one GigaSMART group.

2.

Different first level maps with the same network ports can use the same vport. However, you must keep in mind the limitation described in Rule 1.

3.

Different first level maps with different network ports can use the same vport. However, you must keep in mind the case described in Rule 2.

4.

Different vports can be configured on the same GigaSMART group, but must be used in different maps.

5.

A GigaSMART operation can only belong to one GigaSMART engine group.

6.

In a first level map, you can specify a vport but not a GigaSMART operation.

7.

The vport and the GigaSMART operation used in a second level map must be defined on the same GigaSMART group.

8.

In a second level map, a maximum of 5 maps are allowed to be attached to a vport. The maximum number of gsrules in each map is 5. The maximum number of flowrules in each map is 32.

Note:  Starting in software version 4.7, this limit is increased for GTP only. Refer to GigaSMART GTP Whitelisting and GTP Flow Sampling. Starting in software version 5.2, this limit is increased for APF and ASF. Refer to  GigaSMART Adaptive Packet Filtering (APF) and GigaSMART Application Session Filtering (ASF) and Buffer ASF.

9.

Multiple GTP flow sampling maps can receive traffic from the same virtual port when GTP Overlap is enabled.
