SET SECURITY_ADVANCED PORT GROUP_CODE_(A,B)
SET
SECURITY_ADVANCED
PORT
GROUP_CODE_(A,B)
Use the SET SECURITY_ADVANCED PORT GROUP_CODE_(A,B) command to
assign the same MAC address to two ports on an Ethernet network that has a
CoreBuilder 5000 Ethernet Private Line Card assigned to it. Group codes enable
you to assign a single MAC address to multiple ports on a secure network. This
is an important feature when you use two ports to form a redundant link to a
node. You can also assign each port to a maximum of two group codes. Refer
to the module user guide for a sample configuration that uses group codes.
If you assign multiple ports to a single group code, data sourced from addresses
also associated with the group code are transmitted to the network.
Group code 256 is a global group code
.
The global group code lets certain ports
route packets with unknown destinations. If, for example, one of the ports on a
media module connects to another hub or to an external bridge, you must
configure that port using the global group code. This prevents traffic destined
for another hub from being jammed.
If you configure a port with jamming and assign the global group code to that
port, any packets that the system transmits on the originating hub that are
not
destined for a node on a remote hub are still jammed at that port. Only packets
with an unknown destination are sent to the remote hub.
Format
Example
The following command assigns a group code a value of 23 on port 5.1:
CB5000> set security_advanced port 5.1 group_code_a 23
Port 05.01 group_code_A set to 23.

slot (1 through 17) is the slot number location of a module in the
hub and port (1 through 40) is the port number on the specified
