The user can form groups of SUs at the BSU which define the filtering criteria. All data to/from SUs belonging to the same
group are bridged. If an SU does not belong to any group, the BSU discards the data.
The user can also configure a Security Gateway to block traffic between SUs connected to different BSUs. All packets destined
for SUs not connected to the same BSU are forwarded to the Security Gateway MAC address (configured under Security
Gateway).
The following rules apply to Intra Cell Blocking Groups:

an SU can be assigned to more than one group.

an SU that has not been assigned to any group cannot communicate to any other SU connected to the same or
different BSU.
5.10.6.0.1 Example of Intra-Cell Blocking Groups
Assume that four Intra Cell Blocking Groups have been configured on a BSU. SUs 1 through 10 are registered to the BSU.
In this example, SU1 belongs to two groups, Group 1 and Group 3. Therefore, packets from SU1 destined to SU4, SU5, SU6
and SU7 are not blocked. However, SU9 belongs to group 4 only and packets from SU9 are blocked unless sent to SU8 or SU
10.
To configuring Intra-Cell Blocking parameters, navigate to ADVANCED CONFIGURATION > Filtering> WORP Intra Cell
Blocking. The following screen appears:
